    Local journalism is a critical “gate” to engage Americans on climate change

    by

    Last year, Pew Research Center data revealed that only 37 percent of Americans said addressing climate change should be a top priority for the president and Congress. Furthermore, climate change was ranked 17th out of 21 national issues included in a Pew survey. 

    But in reality, it’s not that Americans don’t care about climate change, says celebrated climate scientist and communicator MIT Professor Katharine Hayhoe. It’s that they don’t know that they already do. 

    To get Americans to care about climate change, she adds, it’s imperative to guide them to their gate. At first, it might not be clear where that gate is. But it exists. 

    That message was threaded through the Connecting with Americans on Climate Change webinar last fall, which featured a discussion with Hayhoe and the five journalists who made up the 2023 cohort of the MIT Environmental Solutions Journalism Fellowship. Hayhoe referred to a “gate” as a conversational entry point about climate impacts and solutions. The catch? It doesn’t have to be climate-specific. Instead, it can focus on the things that people already hold close to their heart.

    “If you show people … whether it’s a military veteran or a parent or a fiscal conservative or somebody who is in a rural farming area or somebody who loves kayaking or birds or who just loves their kids … how they’re the perfect person to care [about climate change], then it actually enhances their identity to advocate for and adopt climate solutions,” said Hayhoe. “It makes them a better parent, a more frugal fiscal conservative, somebody who’s more invested in the security of their country. It actually enhances who they already are instead of trying to turn them into someone else.”

    The MIT Environmental Solutions Journalism Fellowship provides financial and technical support to journalists dedicated to connecting local stories to broader climate contexts, especially in parts of the country where climate change is disputed or underreported. 

    Climate journalism is typically limited to larger national news outlets that have the resources to employ dedicated climate reporters. And since many local papers are already struggling — with the country on track to lose a third of its papers by the end of next year, leaving over 50 percent of counties in the United States with just one or no local news outlets — local climate beats can be neglected. This makes the work executed by the ESI’s fellows all the more imperative. Because for many Americans, the relevance of these stories to their own community is their gate to climate action. 

    “This is the only climate journalism fellowship that focuses exclusively on local storytelling,” says Laur Hesse Fisher, program director at MIT ESI and founder of the fellowship. “It’s a model for engaging some of the hardest audiences to reach: people who don’t think they care much about climate change. These talented journalists tell powerful, impactful stories that resonate directly with these audiences.”

    From March to June, the second cohort of ESI Journalism Fellows pursued local, high-impact climate reporting in Montana, Arizona, Maine, West Virginia, and Kentucky. 

    Collectively, their 26 stories had over 70,000 direct visits on their host outlets’ websites as of August 2023, gaining hundreds of responses from local voters, lawmakers, and citizen groups. Even though they targeted local audiences, they also had national appeal, as they were republished by 46 outlets — including Vox, Grist, WNYC, WBUR, the NPR homepage, and three separate stories on NPR’s “Here & Now” program, which is broadcast by 45 additional partner radio stations across the country — with a collective reach in the hundreds of thousands. 

    Micah Drew published an eight-part series in The Flathead Beacon titled, “Montana’s Climate Change Lawsuit.” It followed a landmark case of 16 young people in Montana suing the state for violating their right to a “clean and healthful environment.” Of the plaintiffs, Drew said, “They were able to articulate very clearly what they’ve seen, what they’ve lived through in a pretty short amount of life. Some of them talked about wildfires — which we have a lot of here in Montana — and [how] wildfire smoke has canceled soccer games at the high school level. It cancels cross-country practice; it cancels sporting events. I mean, that’s a whole section of your livelihood when you’re that young that’s now being affected.”

    Joan Meiners is a climate news reporter for the Arizona Republic. Her five-part series was situated at the intersection of Phoenix’s extreme heat and housing crises. “I found that we are building three times more sprawling, single-family detached homes … as the number of apartment building units,” she says. “And with an affordability crisis, with a climate crisis, we really need to rethink that. The good news, which I also found through research for this series … is that Arizona doesn’t have a statewide building code, so each municipality decides on what they’re going to require builders to follow … and there’s a lot that different municipalities can do just by showing up to their city council meetings [and] revising the building codes.”

    For The Maine Monitor, freelance journalist Annie Ropeik generated a four-part series, called “Hooked on Heating Oil,” on how Maine came to rely on oil for home heating more than any other state. When asked about solutions, Ropeik says, “Access to fossil fuel alternatives was really the central equity issue that I was looking at in my project, beyond just, ‘Maine is really relying on heating oil, that obviously has climate impacts, it’s really expensive.’ What does that mean for people in different financial situations, and what does that access to solutions look like for those different communities? What are the barriers there and how can we address those?”

    Energy and environment reporter Mike Tony created a four-part series in The Charleston Gazette-Mail on West Virginia’s flood vulnerabilities and the state’s lack of climate action. On connecting with audiences, Tony says, “The idea was to pick a topic like flooding that really affects the whole state, and from there, use that as a sort of an inroad to collect perspectives from West Virginians on how it’s affecting them. And then use that as a springboard to scrutinizing the climate politics that are precluding more aggressive action.”

    Finally, Ryan Van Velzer, Louisville Public Media’s energy and environment reporter, covered the decline of Kentucky’s fossil fuel industry and offered solutions for a sustainable future in a four-part series titled, “Coal’s Dying Light.” For him, it was “really difficult to convince people that climate change is real when the economy is fundamentally intertwined with fossil fuels. To a lot of these people, climate change, and the changes necessary to mitigate climate change, can cause real and perceived economic harm to these communities.” 

    With these projects in mind, someone’s gate to caring about climate change is probably nearby — in their own home, community, or greater region. 

    It’s likely closer than they think.

      Preparing Colombia’s cities for life amid changing forests

      by

      It was an uncharacteristically sunny morning as Marcela Angel MCP ’18, flanked by a drone pilot from the Boston engineering firm AirWorks and a data collection team from the Colombian regional environmental agency Corpoamazonia, climbed a hill in the Andes Mountains of southwest Colombia. The area’s usual mountain cloud cover — one of the major challenges to working with satellite imagery or flying UAVs (unpiloted aerial vehicles, or drones) in the Pacific highlands of the Amazon — would roll through in the hours to come. But for now, her team had chosen a good day to hike out for their first flight. Angel is used to long travel for her research. Raised in Bogotá, she maintained strong ties to Colombia throughout her master’s program in the MIT Department of Urban Studies and Planning (DUSP). Her graduate thesis, examining Bogotá’s management of its public green space, took her regularly back to her hometown, exploring how the city could offer residents more equal access to the clean air, flood protection and day-to-day health and social benefits provided by parks and trees. But the hill she was hiking this morning, outside the remote city of Mocoa, had taken an especially long time to climb: five years building relationships with the community of Mocoa and the Colombian government, recruiting project partners, and navigating the bureaucracy of bringing UAVs into the country. Now, her team finally unwrapped their first, knee-high drone from its tarp and set it carefully in the grass. Under the gathering gray clouds, the buzz of its rotors joined the hum of insects in the trees, and the machine at last took to the skies.

      From Colombia to Cambridge

      “I actually grew up on the last street before the eastern mountains reserve,” Angel says of her childhood in Bogotá. “I’ve always been at that border between city and nature.” This idea, that urban areas are married to the ecosystems around them, would inform Angel’s whole education and career. Before coming to MIT, she studied architecture at Bogotá’s Los Andes University; for her graduation project she proposed a plan to resettle an informal neighborhood on Bogotá’s outskirts to minimize environmental risks to its residents. Among her projects at MIT was an initiative to spatially analyze Bogotá’s tree canopy, providing data for the city to plan a tree-planting program as a strategy to give vulnerable populations in the city more access to nature. And she was naturally intrigued when Colombia’s former minister of environment and sustainable development came to MIT in 2017 to give a guest presentation to the DUSP master’s program. The minister, Luis Gilberto Murillo (now the Colombian ambassador to the United States), introduced the students to the challenges triggered by a recent disaster in the city of Mocoa, on the border between the lowland Amazon and the Andes Mountains. Unprecedented rainstorms had destabilized the surrounding forests, and that April a devastating flood and landslide had killed hundreds of people and destroyed entire neighborhoods. And as climate change contributed to growing rainfall in the region, the risks of more landslide events were rising. Murillo provided useful insights into how city planning decisions had contributed to the crisis. But he also asked for MIT’s support addressing future landslide risks in the area. Angel and Juan Camilo Osorio, a PhD candidate at DUSP, decided to take up the challenge, and in January 2018 and 2019, a research delegation from MIT traveled to Colombia for a newly-created graduate course. Returning once again to Bogotá, Angel interviewed government agencies and nonprofits to understand the state of landslide monitoring and public policy. In Mocoa, further interviews and a series of workshops helped clarify what locals needed most and what MIT could provide: better information on where and when landslides might strike, and a process to increase risk awareness and involve traditionally marginalized groups in decision-making processes around that risk. Over the coming year, a core team formed to put the insights from this trip into action, including Angel, Osorio, postdoc Norhan Bayomi of the MIT Environmental Solutions Initiative (ESI) and MIT Professor John Fernández, director of the ESI and one of Angel’s mentors at DUSP. After a second visit to Mocoa that brought into the fold Indigenous groups, environmental agencies, and the national army, a plan was formed: MIT would partner with Corpoamazonia and build a network of community researchers to deploy and test drone technology and machine learning models to monitor the mountain forests for both landslide risks and signs of forest health, while implementing a participatory planning process with residents. “What our projects aim to do is give the communities new tools to continue protecting and restoring the forest,” says Angel, “and support new and inclusive development models, even in the face of new challenges.”

      Lifelines for the climate

      The goal of tropical forest conservation is an urgent one. As forests are cut down, their trees and soils release carbon they have stored over millennia, adding huge amounts of heat-trapping carbon dioxide to the atmosphere. Deforestation, mainly in the tropics, is now estimated to contribute more to climate change than any country besides the United States and China — and once lost, tropical forests are exceptionally hard to restore. “Tropical forests should be a natural way to slow and reverse climate change,” says Angel. “And they can be. But today, we are reaching critical tipping points where it is just the opposite.” This became the motivating force for Angel’s career after her graduation. In 2019, Fernández invited her to join the ESI and lead a new Natural Climate Solutions Program, with the Mocoa project as its first centerpiece. She quickly mobilized the partners to raise funding for the project from the Global Environmental Facility and the CAF Development Bank of Latin America and the Caribbean, and recruited additional partners including MIT Lincoln Laboratories, AirWorks, and the Pratt Institute, where Osorio had become an assistant professor. She hired machine learning specialists from MIT to begin design on UAVs’ data processing, and helped assemble a local research network in Mocoa to increase risk awareness, promote community participation, and better understand what information city officials and community groups needed for city planning and conservation. “This is the amazing thing about MIT,” she says. “When you study a problem here, you’re not just playing in a sandbox. Everyone I’ve worked with is motivated by the complexity of the technical challenge and the opportunity for meaningful engagement in Mocoa, and hopefully in many more places besides.” At the same time, Angel created opportunities for the next generation of MIT graduate students to follow in her footsteps. With Fernández and Bayomi, she created a new course, 4.S23 (Biodiversity and Cities), in which students traveled to Colombia to develop urban planning strategies for the cities of Quidbó and Leticia, located in carbon-rich and biodiverse areas. The course has been taught twice, with Professor Gabriella Carolini joining the teaching team for spring 2023, and has already led to a student report to city officials in Quidbó recommending ways to enhance biodiversity and adapt to climate change as the city grows, a multi-stakeholder partnership to train local youth and implement a citizen-led biodiversity survey, and a seed grant from the MIT Climate and Sustainability Consortium to begin providing both cities detailed data on their tree cover derived from satellite images. “These regions face serious threats, especially on a warming planet, but many of the solutions for climate change, biodiversity conservation, and environmental equity in the region go hand-in-hand,” Angel says. “When you design a city to use fewer resources, to contribute less to climate change, it also causes less pressure on the environment around it. When you design a city for equity and quality of life, you’re giving attention to its green spaces and what they can provide for people and as habitat for other species. When you protect and restore forests, you’re protecting local bioeconomies.”

      Bringing the data home

      Meanwhile, in Mocoa, Angel’s original vision is taking flight. With the team’s test flights behind them, they can now begin creating digital models of the surrounding area. Regular drone flights and soil samples will fill in changing information about trees, water, and local geology, allowing the project’s machine learning specialists to identify warning signs for future landslides and extreme weather events. More importantly, there is now an established network of local community researchers and leaders ready to make use of this information. With feedback from their Mocoan partners, Angel’s team has built a prototype of the online platform they will use to share their UAV data; they’re now letting Mocoa residents take it for a test drive and suggest how it can be made more user-friendly. Her visit this January also paved the way for new projects that will tie the Environmental Solutions Initiative more tightly to Mocoa. With her project partners, Angel is exploring developing a course to teach local students how to use UAVs like the ones her team is flying. She is also considering expanded efforts to collect the kind of informal knowledge of Mocoa, on the local ecology and culture, that people everywhere use in making their city planning and emergency response decisions, but that is rarely codified and included in scientific risk analyses. It’s a great deal of work to offer this one community the tools to adapt successfully to climate change. But even with all the robotics and machine learning models in the world, this close, slow-unfolding engagement, grounded in trust and community inclusion, is what it takes to truly prepare people to confront profound changes in their city and environment. “Protecting natural carbon sinks is a global socio-environmental challenge, and one where it is not enough for MIT to just contribute to the knowledge base or develop a new technology,” says Angel. “But we can help mobilize decision-makers and nontraditional actors, and design more inclusive and technology-enhanced processes, to make this easier for the people who have lifelong stakes in these ecosystems. That is the vision.” More

      Celebrating a decade of a more sustainable MIT, with a focus on the future

      by

      When MIT’s Office of Sustainability (MITOS) first launched in 2013, it was charged with integrating sustainability across all levels of campus by engaging the collective brainpower of students, staff, faculty, alumni, and partners. At the eighth annual Sustainability Connect, MITOS’s signature event, held nearly a decade later, the room was filled with MIT community members representing 67 different departments, labs, and centers — demonstrating the breadth of engagement across MIT.

      Held on Feb. 14 and hosting more than 100 staff, students, faculty, and researchers, the event was a forum on the future of sustainability leadership at MIT, designed to reflect on the work that had brought MIT to its present moment — focused on a net-zero future by 2026 and elimination of direct campus emissions by 2050 — and to plan forward.

      Director of Sustainability Julie Newman kicked off the day by reflecting on some of the questions that influenced the development of the MITOS framework, including: “How can MIT be a game-changing force for campus sustainability in the 21st century?” and “What are we solving for?” Newman shared that while these questions still drive the work of the office, considerations of the impact of this work have evolved. “We are becoming savvier at asking the follow-up question to these prompts,” she explained. “Are our solutions causing additional issues that we were remiss to ask, such as the impact on marginalized communities, unanticipated human health implications, and new forms of extraction?” Newman then encouraged attendees to think about these types of questions when envisioning and planning for the next decade of sustainability at MIT.

      While the event focused broadly on connecting the sustainability community at MIT, the day’s sessions tracked closely to the climate action plans that guided the office, 2015’s A Plan for Action on Climate Change and the current Fast Forward: MIT’s Climate Action Plan for the Decade. Both plans call for using the campus as a test bed, and at “A Model for Change: Field Reports from Campus as a Test Bed,” panelists Miho Mazereeuw, associate professor of architecture and urbanism, director of the Urban Risk Lab, and MITOS Faculty Fellow; Ken Strzepek, MITOS Faculty Fellow and research scientist at the MIT Center for Global Change Science; and Ippolyti Dellatolas graduate student and MITOS Climate Action Sustainability researcher shared ways in which they utilize the MIT campus as a test bed to design, study, and implement solutions related to flood risk, campus porosity, emissions reductions, and climate policy — efforts that can also inform work beyond MIT. Dellatolas reflected on success in this space. “With a successful campus as a test bed project, there is either output: we achieved these greenhouse gas emissions reductions or we learned something valuable in the process, so even if it fails, we understand why it failed and we can lend that knowledge to the next project,” she explained.

      Later in the morning, an “On the Horizon” panel focused on what key areas of focus, partnerships, and evolutions will propel the campus forward — anchored in the intersectional topics of decarbonization, climate justice, and experiential learning. To kick off the discussion, panelists John Fernández, director of the Environmental Solutions Initiative and professor of architecture; Joe Higgins, vice president for campus services and stewardship; Susy Jones, senior sustainability project manager; and Kate Trimble, senior associate dean for experiential learning shared which elements of their work have shifted in the last five years. Higgins commented on exciting progress being made in the space of renewables, electrification, smart thermostats, offshore wind, and other advances both at MIT and the municipal level. “You take this moment, and you think, these things weren’t in the moment five years ago when we were here on this stage. It brings a sense of abundance and optimism,” he concluded.

      Jones, for her part, shared how thinking about food and nutrition evolved over this period. “We’ve developed a lot of programming around nutrition. In the past few years, this new knowledge around the climate impact of our food system has joined the conversation,” she shared. “I think it’s really important to add that to the many years and decades of work that have been going on around food justice and food access and bring that climate conversation into that piece and acknowledge that, yes, the food system is accountable for about a quarter of global greenhouse gases.”

      Throughout the event, attendees were encouraged to share their questions and ideas for the future. In the closing workshop, “The Future of Sustainability at MIT,” attendees responded to questions such as, “What gives you hope?” and “What are we already doing well at MIT, what could we do more of?” The answers and ideas — which ranged from fusion to community co-design to a continued focus on justice — will inform MITOS’s work going forward, says Newman. “This is an activity we did within our core team, and the answers were so impactful and candid that we thought to bring it to the larger community to learn even more,” she says.

      That larger community was also recognized for their contributions with the first-ever Sustainability Awards, which honored nominated staff and students from departments across MIT for their contributions to building a more sustainable MIT. “This year we had a special opportunity to spotlight some of those individuals and teams leading transformative change at MIT,” explained Newman. “But everyone in the room and everyone working on sustainability at MIT in some way are our partners in this work. Our office could not do what we do without them.” More

      Rescuing small plastics from the waste stream

      by

      As plastic pollution continues to mount, with growing risks to ecosystems and wildlife, manufacturers are beginning to make ambitious commitments to keep new plastics out of the environment. A growing number have signed onto the U.S. Plastics Pact, which pledges to make 100 percent of plastic packaging reusable, recyclable, or compostable, and to see 50 percent of it effectively recycled or composted, by 2025.

      But for companies that make large numbers of small, disposable plastics, these pocket-sized objects are a major barrier to realizing their recycling goals.

      “Think about items like your toothbrush, your travel-size toothpaste tubes, your travel-size shampoo bottles,” says Alexis Hocken, a second-year PhD student in the MIT Department of Chemical Engineering. “They end up actually slipping through the cracks of current recycling infrastructure. So you might put them in your recycling bin at home, they might make it all the way to the sorting facility, but when it comes down to actually sorting them, they never make it into a recycled plastic bale at the very end of the line.”

      Now, a group of five consumer products companies is working with MIT to develop a sorting process that can keep their smallest plastic products inside the recycling chain. The companies — Colgate-Palmolive, Procter & Gamble, the Estée Lauder Companies, L’Oreal, and Haleon — all manufacture a large volume of “small format” plastics, or products less than two inches long in at least two dimensions. In a collaboration with Brad Olsen, the Alexander and I. Michael Kasser (1960) Professor of Chemical Engineering; Desiree Plata, an associate professor of civil and environmental engineering; the MIT Environmental Solutions Initiative; and the nonprofit The Sustainability Consortium, these companies are seeking a prototype sorting technology to bring to recycling facilities for large-scale testing and commercial development.

      Working in Olsen’s lab, Hocken is coming to grips with the complexity of the recycling systems involved. Material recovery facilities, or MRFs, are expected to handle products in any number of shapes, sizes, and materials, and sort them into a pure stream of glass, metal, paper, or plastic. Hocken’s first step in taking on the recycling project was to tour one of these MRFs in Portland, Maine, with Olsen and Plata.

      “We could literally see plastics just falling from the conveyor belts,” she says. “Leaving that tour, I thought, my gosh! There’s so much improvement that can be made. There’s so much impact that we can have on this industry.”

      From designing plastics to managing them

      Hocken always knew she wanted to work in engineering. Growing up in Scottsdale, Arizona, she was able to spend time in the workplace with her father, an electrical engineer who designs biomedical devices. “Seeing him working as an engineer, and how he’s solving these really important problems, definitely sparked my interest,” she says. “When it came time to begin my undergraduate degree, it was a really easy decision to choose engineering after seeing the day-to-day that my dad was doing in his career.”

      At Arizona State University, she settled on chemical engineering as a major and began working with polymers, coming up with combinations of additives for 3D plastics printing that could help fine-tune how the final products behaved. But even working with plastics every day, she rarely thought about the implications of her work for the environment.

      “And then in the spring of my final year at ASU, I took a class about polymers through the lens of sustainability, and that really opened my eyes,” Hocken remembers. The class was taught by Professor Timothy Long, director of the Biodesign Center for Sustainable Macromolecular Materials and Manufacturing and a well-known expert in the field of sustainable plastics. “That first session, where he laid out all of the really scary facts surrounding the plastics crisis, got me very motivated to look more into that field.”

      At MIT the next year, Hocken sought out Olsen as her advisor and made plastics sustainability her focus from the start.

      “Coming to MIT was my first time venturing outside of the state of Arizona for more than a three-month period,” she says. “It’s been really fun. I love living in Cambridge and the Boston area. I love my labmates. Everyone is so supportive, whether it’s to give me advice about some science that I’m trying to figure out, or just give me a pep talk if I’m feeling a little discouraged.”

      A challenge to recycle

      A lot of plastics research today is devoted to creating new materials — including biodegradable ones that are easier for natural ecosystems to absorb, and highly recyclable ones that hold their properties better after being melted down and recast.

      But Hocken also sees a huge need for better ways to handle the plastics we’re already making. “While biodegradable and sustainable polymers represent a very important route, and I think they should certainly be further pursued, we’re still a ways away from that being a reality universally across all plastic packaging,” she says. As long as large volumes of conventional plastic are coming out of factories, we’ll need innovative ways to stop it from piling onto the mountain of plastic pollution. In one of her projects, Hocken is trying to come up with new uses for recycled plastic that take advantage of its lost strength to produce a useful, flexible material similar to rubber.

      The small-format recycling project also falls in this category. The companies supporting the project have challenged the MIT team to work with their products exactly as currently manufactured — especially because their competitors use similar packaging materials that will also need to be covered by any solution the MIT team devises.

      The challenge is a large one. To kick the project off, the participating companies sent the MIT team a wide range of small-format products that need to make it through the sorting process. These include containers for lip balm, deodorant, pills, and shampoo, and disposable tools like toothbrushes and flossing picks. “A constraint, or problem I foresee, is just how variable the shapes are,” says Hocken. “A flossing pick versus a toothbrush are very different shapes.”

      Nor are they all made of the same kind of plastic. Many are made of polyethylene terephthalate (PET, type 1 in the recycling label system) or high-density polyethylene (HDPE, type 2), but nearly all of the seven recycling categories are represented among the sample products. The team’s solution will have to handle them all.

      Another obstacle is that the sorting process at a large MRF is already very complex and requires a heavy investment in equipment. The waste stream typically goes through a “glass breaker screen” that shatters glass and collects the shards; a series of rotating rubber stars to pull out two-dimensional objects, collecting paper and cardboard; a system of magnets and eddy currents to attract or repel different metals; and finally, a series of optical sorters that use infrared spectroscopy to identify the various types of plastics, then blow them down different chutes with jets of air. MRFs won’t be interested in adopting additional sorters unless they’re inexpensive and easy to fit into this elaborate stream.

      “We’re interested in creating something that could be retrofitted into current technology and current infrastructure,” Hocken says.

      Shared solutions

      “Recycling is a really good example of where pre-competitive collaboration is needed,” says Jennifer Park, collective action manager at The Sustainability Consortium (TSC), who has been working with corporate stakeholders on small format recyclability and helped convene the sponsors of this project and organize their contributions. “Companies manufacturing these products recognize that they cannot shift entire systems on their own. Consistency around what is and is not recyclable is the only way to avoid confusion and drive impact at scale.

      “Additionally, it is interesting that consumer packaged goods companies are sponsoring this research at MIT which is focused on MRF-level innovations. They’re investing in innovations that they hope will be adopted by the recycling industry to make progress on their own sustainability goals.”

      Hocken believes that, despite the challenges, it’s well worth pursuing a technology that can keep small-format plastics from slipping through MRFs’ fingers.

      “These are products that would be more recyclable if they were easier to sort,” she says. “The only thing that’s different is the size. So you can recycle both your large shampoo bottle and the small travel-size one at home, but the small one isn’t guaranteed to make it into a plastic bale at the end. If we can come up with a solution that specifically targets those while they’re still on the sorting line, they’re more likely to end up in those plastic bales at the end of the line, which can be sold to plastic reclaimers who can then use that material in new products.”

      “TSC is really excited about this project and our collaboration with MIT,” adds Park. “Our project stakeholders are very dedicated to finding a solution.”

      Mining for the clean energy transition

      by

      In a world powered increasingly by clean energy, drilling for oil and gas will gradually give way to digging for metals and minerals. Today, the “critical minerals” used to make electric cars, solar panels, wind turbines, and grid-scale battery storage are facing soaring demand — and some acute bottlenecks as miners race to catch up.

      According to a report from the International Energy Agency, by 2040, the worldwide demand for copper is expected to roughly double; demand for nickel and cobalt will grow at least sixfold; and the world’s hunger for lithium could reach 40 times what we use today.

      “Society is looking to the clean energy transition as a way to solve the environmental and social harms of climate change,” says Scott Odell, a visiting scientist at the MIT Environmental Solutions Initiative (ESI), where he helps run the ESI Mining, Environment, and Society Program, who is also a visiting assistant professor at George Washington University. “Yet mining the materials needed for that transition would also cause social and environmental impacts. So we need to look for ways to reduce our demand for minerals, while also improving current mining practices to minimize social and environmental impacts.”

      ESI recently hosted the inaugural MIT Conference on Mining, Environment, and Society to discuss how the clean energy transition may affect mining and the people and environments in mining areas. The conference convened representatives of mining companies, environmental and human rights groups, policymakers, and social and natural scientists to identify key concerns and possible collaborative solutions.

      “We can’t replace an abusive fossil fuel industry with an abusive mining industry that expands as we move through the energy transition,” said Jim Wormington, a senior researcher at Human Rights Watch, in a panel on the first day of the conference. “There’s a recognition from governments, civil society, and companies that this transition potentially has a really significant human rights and social cost, both in terms of emissions […] but also for communities and workers who are on the front lines of mining.”

      That focus on communities and workers was consistent throughout the three-day conference, as participants outlined the economic and social dimensions of standing up large numbers of new mines. Corporate mines can bring large influxes of government revenue and local investment, but the income is volatile and can leave policymakers and communities stranded when production declines or mineral prices fall. On the other hand, “artisanal” mining operations are an important source of critical minerals, but are hard to regulate and subject to abuses from brokers. And large reserves of minerals are found in conservation areas, regions with fragile ecosystems and experiencing water shortages that can be exacerbated by mining, in particular on Indigenous-controlled lands and other places where mine openings are deeply fraught.

      “One of the real triggers of conflict is a dissatisfaction with the current model of resource extraction,” said Jocelyn Fraser of the University of British Columbia in a panel discussion. “One that’s failed to support the long-term sustainable development of regions that host mining operations, and yet imposes significant local social and environmental impacts.”

      All these challenges point toward solutions in policy and in mining companies’ relationships with the communities where they work. Participants highlighted newer models of mining governance that can create better incentives for the ways mines operate — from full community ownership of mines to recognizing community rights to the benefits of mining to end-of-life planning for mines at the time they open.

      Many of the conference speakers also shared technological innovations that may help reduce mining challenges. Some operations are investing in desalination as alternative water sources in water-scarce regions; low-carbon alternatives are emerging to many of the fossil fuel-powered heavy machines that are mainstays of the industry; and work is being done to reclaim valuable minerals from mine tailings, helping to minimize both waste and the need to open new extraction sites.

      Increasingly, the mining industry itself is recognizing that reforms will allow it to thrive in a rapid clean-energy transition. “Decarbonization is really a profitability imperative,” said Kareemah Mohammed, managing director for sustainability services at the technology consultancy Accenture, on the conference’s second day. “It’s about securing a low-cost and steady supply of either minerals or metals, but it’s also doing so in an optimal way.”

      The three-day conference attracted over 350 attendees, from large mining companies, industry groups, consultancies, multilateral institutions, universities, nongovernmental organizations (NGOs), government, and more. It was held entirely virtually, a choice that helped make the conference not only truly international — participants joined from over 27 countries on six continents — but also accessible to members of nonprofits and professionals in the developing world.

      “Many people are concerned about the environmental and social challenges of supplying the clean energy revolution, and we’d heard repeatedly that there wasn’t a forum for government, industry, academia, NGOs, and communities to all sit at the same table and explore collaborative solutions,” says Christopher Noble, ESI’s director of corporate engagement. “Convening, and researching best practices, are roles that universities can play. The conversations at this conference have generated valuable ideas and consensus to pursue three parallel programs: best-in-class models for community engagement, improving ESG metrics and their use, and civil-society contributions to government/industry relations. We are developing these programs to keep the momentum going.”

      The MIT Conference on Mining, Environment, and Society was funded, in part, by Accenture, as part of the MIT/Accenture Convergence Initiative. Additional funding was provided by the Inter-American Development Bank. More

      MIT accelerates efforts on path to carbon reduction goals

      by

      Under its “Fast Forward” climate action plan, which was announced in May 2021, MIT has set a goal of eliminating direct emissions from its campus by 2050. An important near-term milestone will be achieving net-zero emissions by 2026. Many other colleges and universities have set similar targets. What does it take to achieve such a dramatic reduction?

      Since 2014, when MIT launched a five-year plan for action on climate change, net campus emissions have been cut by 20 percent. To meet the 2026 target, and ultimately achieve zero direct emissions by 2050, the Institute is making its campus buildings dramatically more energy efficient, transitioning to electric vehicles (EVs), and enabling large-scale renewable energy projects, among other strategies.

      “This is an ‘all-in’ moment for MIT, and we’re taking comprehensive steps to address our carbon footprint,” says Glen Shor, executive vice president and treasurer. “Reducing our emissions to zero will be challenging, but it’s the right aspiration.”

      “As an energy-intensive campus in an urban setting, our ability to achieve this goal will, in part, depend on the capacity of the local power grid to support the electrification of buildings and transportation, and how ‘green’ that grid electricity will become over time,” says Joe Higgins, MIT’s vice president for campus services and stewardship. “It will also require breakthrough technology improvements and new public policies to drive their adoption. Many of those tech breakthroughs are being developed by our own faculty, and our teams are planning scenarios in anticipation of their arrival.”

      Working toward an energy-efficient campus

      The on-campus reductions have come primarily from a major upgrade to MIT’s Central Utilities Plant, which provides electricity, heating, and cooling for about 80 percent of all Institute buildings. The upgraded plant, which uses advanced cogeneration technology, became fully operational at the end of 2021 and is meeting campus energy needs at greater efficiency and lower carbon intensity (on average 15 to 25 percent cleaner) compared to the regional electricity grid. Carbon reductions from the increased efficiency provided by the enhanced plant are projected to counter the added greenhouse gas emissions caused by recently completed and planned construction and operation of new buildings on campus, especially energy-intensive laboratory buildings.

      Energy from the plant is delivered to campus buildings through MIT’s district energy system, a network of underground pipes and power lines providing electricity, heating, and air conditioning. With this adaptable system, MIT can introduce new technologies as they become available to increase the system’s energy efficiency. The system enables MIT to export power when the regional grid is under stress and to import electricity from the power grid as it becomes cleaner, likely over the next decade as the availability of offshore wind and renewable resources increases. “At the same time, we are reviewing additional technology options such as industrial-scale heat pumps, thermal batteries, geothermal exchange, microreactors, bio-based fuels, and green hydrogen produced from renewable energy,” Higgins says.

      Along with upgrades to the plant, MIT is gradually converting existing steam-based heating systems into more efficient hot-water systems. This long-term project to lower campus emissions requires replacing the vast network of existing steam pipes and infrastructure, and will be phased in as systems need to be replaced. Currently MIT has four buildings that are on a hot-water system, with five more buildings transitioning to hot water by the fall of 2022.  

      Minimizing emissions by implementing meaningful building efficiency standards has been an ongoing strategy in MIT’s climate mitigation efforts. In 2016, MIT made a commitment that all new campus construction and major renovation projects must earn at least Leadership in Energy and Environmental Design (LEED) Gold certification. To date, 24 spaces and buildings at MIT have earned a LEED designation, a performance-based rating system of a building’s environmental attributes associated with its design, construction, operations, and management.

      Current efficiency efforts focus on reducing energy in the 20 buildings that account for more than 50 percent of MIT’s energy usage. One such project under construction aims to improve energy efficiency in Building 46, which houses the Department of Brain and Cognitive Sciences and the Picower Institute for Learning and Memory and is the biggest energy user on the campus because of its large size and high concentration of lab spaces. Interventions include optimizing ventilation systems that will significantly reduce energy use while improving occupant comfort, and working with labs to implement programs such as fume hood hibernation and equipment adjustments. For example, raising ultralow freezer set points by 10 degrees can reduce their energy consumption by as much as 40 percent. Together, these measures are projected to yield a 35 percent reduction in emissions for Building 46, which would contribute to reducing campus-level emissions by 2 percent.

      Over the past decade, in addition to whole building intervention programs, the campus has taken targeted measures in over 100 campus buildings to add building insulation, replace old, inefficient windows, transition to energy-efficient lighting and mechanical systems, optimize lab ventilation systems, and install solar panels on solar-ready rooftops on campus — and will increase the capacity of renewable energy installations on campus by a minimum of 400 percent by 2026. These smaller scale contributions to overall emissions reductions are essential steps in a comprehensive campus effort.

      Electrification of buildings and vehicles

      With an eye to designing for “the next energy era,” says Higgins, MIT is looking to large-scale electrification of its buildings and district energy systems to reduce building use-associated emissions. Currently under renovation, the Metropolitan Storage Warehouse — which will house the MIT School of Architecture and Planning (SA+P) and the newly established MIT Morningside Academy for Design — will be the first building on campus to undergo this transformation by using electric heat pumps as its main heating and supplemental cooling source. The project team, consisting of campus engineering and construction teams as well as the designers, is working with SA+P faculty to design this innovative electrification project. The solution will move excess heat from the district energy infrastructure and nearby facilities to supply the heat pump system, creating a solution that uses less energy — resulting in fewer carbon emissions. 

      Next to building energy use, emissions from on-campus vehicles are a key target for reduction; one of the goals in the “Fast Forward” plan is the electrification of on-campus vehicles. This includes the expansion of electric vehicle charging stations, and work has begun on the promised 200 percent expansion of the number of stations on campus, from 120 to 360. Sites are being evaluated to make sure that all members of the MIT community have easy access to these facilities.

      The electrification also includes working toward replacing existing MIT-owned vehicles, from shuttle buses and vans to pickup trucks and passenger cars, as well as grounds maintenance equipment. Shu Yang Zhang, a junior in the Department of Materials Science and Engineering, is part of an Office of Sustainability student research team that carried out an evaluation of the options available for each type of vehicle and compared both their lifecycle costs and emissions.

      Zhang says the team examined “the specifics of the vehicles that we own, looking at key measures such as fuel economy and cargo capacity,” and determined what alternatives exist in each category. The team carried out a study of the costs for replacing existing vehicles with EVs on the market now, versus buying new gas vehicles or leaving the existing ones in place. They produced a set of specific recommendations about fleet vehicle replacement and charging infrastructure installation on campus that supports both commuters and an MIT EV fleet in the future. According to their estimates, Zhang says, “the costs should be not drastically different” in the long run for the new electric vehicles.

      Strength in numbers

      While a panoply of measures has contributed to the successful offsetting of emissions so far, the biggest single contributor was MIT’s creation of an innovative, collaborative power purchase agreement (PPA) that enabled the construction of a large solar farm in North Carolina, which in turn contributed to the early retirement of a large coal-fired power plant in that region. MIT is committed to buying 73 percent of the power generated by the new facility, which is equivalent to approximately 40 percent of the Institute’s electricity use.

      That PPA, which was a collaboration between three institutions, provided a template that has already been emulated by other institutions, in many cases enabling smaller organizations to take part in such a plan and achieve greater offsets of their carbon emissions than might have been possible acting on their own. Now, MIT is actively pursuing new, larger variations on that plan, which may include a wider variety of organizational participants, perhaps including local governments as well as institutions and nonprofits. The hope is that, as was the case with the original PPA, such collaborations could provide a model that other institutions and organizations may adopt as well.

      Strategic portfolio agreements like the PPA will help achieve net zero emissions on campus while accelerating the decarbonization of regional electricity grids — a transformation critical to achieving net zero emissions, alongside all the work that continues to reduce the direct emissions from the campus itself.

      “PPAs play an important role in MIT’s net zero strategy and have an immediate and significant impact in decarbonization of regional power grids by enabling renewable energy projects,” says Paul L. Joskow, the Elizabeth and James Killian Professor of Economics. “Many well-known U.S. companies and organizations that are seeking to enable and purchase CO2-free electricity have turned to long-term PPAs selected through a competitive procurement process to help to meet their voluntary internal decarbonization commitments. While there are still challenges regarding organizational procurements — including proper carbon emissions mitigation accounting, optimal contract design, and efficient integration into wholesale electricity markets — we are optimistic that MIT’s efforts and partnerships will contribute to resolving some of these issues.”

      Addressing indirect sources of emissions

      MIT’s examination of emissions is not limited to the campus itself but also the indirect sources associated with the Institute’s operations, research, and education. Of these indirect emissions, the three major ones are business travel, purchased goods and services, and construction of buildings, which are collectively larger than the total direct emissions from campus.

      The strategic sourcing team in the Office of the Vice President for Finance has been working to develop opportunities and guidelines for making it easier to purchase sustainable products, for everything from office paper to electronics to lab equipment. Jeremy Gregory, executive director of MIT’s Climate and Sustainability Consortium, notes that MIT’s characteristic independent spirit resists placing limits on what products researchers can buy, but, he says, “we have opportunities to centralize some of our efforts and empower our community to choose low-impact alternatives when making procurement decisions.”

      The path forward

      The process of identifying and implementing MIT’s carbon reductions will be supported, in part, by the Carbon Footprint Working Group, which was launched by the Climate Nucleus, a new body MIT created to manage the implementation of the “Fast Forward” climate plan. The nucleus includes a broad representation from MIT’s departments, labs, and centers that are working on climate change issues. “We’ve created this internal structure in an effort to integrate operational expertise with faculty and student research innovations,” says Director of Sustainability Julie Newman.

      Whatever measures end up being adopted to reduce energy and associated emissions, their results will be made available continuously to members of the MIT community in real-time, through a campus data gateway, Newman says — a degree of transparency that is exceptional in higher education. “If you’re interested in supporting all these efforts and following this,” she says, “you can track the progress via Energize MIT,” a set of online visualizations that display various measures of MIT’s energy usage and greenhouse gas emissions over time.

      3Q: How MIT is working to reduce carbon emissions on our campus

      by

      Fast Forward: MIT’s Climate Action Plan for the Decade, launched in May 2021, charges MIT to eliminate its direct carbon emissions by 2050. Setting an interim goal of net zero emissions by 2026 is an important step to getting there. Joe Higgins, vice president for campus services and stewardship, speaks here about the coordinated, multi-team effort underway to address the Institute’s carbon-reduction goals, the challenges and opportunities in getting there, and creating a blueprint for a carbon-free campus in 2050.

      Q: The Fast Forward plan laid out specific goals for MIT to address its own carbon footprint. What has been the strategy to tackle these priorities?

      A: The launch of the Fast Forward Climate Action Plan empowered teams at MIT to expand the scope of our carbon reduction tasks beyond the work we’ve been doing to date. The on-campus activities called for in the plan range from substantially expanding our electric vehicle infrastructure on campus, to increasing our rooftop solar installations, to setting impact goals for food, water, and waste systems. Another strategy utilizes artificial intelligence to further reduce energy consumption and emissions from our buildings. When fully implemented, these systems will adjust a building’s temperature setpoints throughout the day while maintaining occupant comfort, and will use occupancy data, weather forecasts, and carbon intensity projections from the grid to make more efficient use of energy. 

      We have tremendous momentum right now thanks to the progress made over the past decade by our teams — which include planners, designers, engineers, construction managers, and sustainability and operations experts. Since 2014, our efforts to advance energy efficiency and incorporate renewable energy have reduced net emissions on campus by 20% (from a 2014 baseline) despite significant campus growth. One of our current goals is to further reduce energy use in high-intensity research buildings — 20 of our campus buildings consume more than 50% of our energy. To reduce energy usage in these buildings we have major energy retrofit projects in design or in planning for buildings 32, 46, 68, 76, E14, and E25, and we expect this work will reduce overall MIT emissions by an additional 10 to 15%.

      Q: The Fast Forward plan acknowledges the challenges we face in our efforts to reach our campus emission reduction goals, in part due to the current state of New England’s electrical grid. How does MIT’s district energy system factor into our approach? 

      A: MIT’s district energy system is a network of underground pipes and power lines that moves energy from the Central Utilities Plant (CUP) around to the vast majority of Institute buildings to provide electricity, heating, and air conditioning. Using a closed-loop, central-source system like this enables MIT to operate more efficiently by using less energy to heat and cool its buildings and labs, and by maintaining better load control to accommodate seasonal variations in peak demand.

      When the new MIT campus was built in Cambridge in 1916, it included a centralized state-of-the-art steam and electrical power plant that would service the campus buildings. This central district energy approach allowed MIT to avoid having individual furnaces in each building and to easily incorporate progressively cleaner fuel sources campus-wide over the years. After starting with coal as a primary energy source, MIT transitioned to fuel oil, then to natural gas, and then to cogeneration in 1995 — and each step has made the campus more energy efficient. Our continuous investment in a centralized infrastructure has facilitated our ability to improve energy efficiency while adding capacity; as new technologies become available, we can implement them across the entire campus. Our district energy system is very adaptable to seasonal variations in demand for cooling, heating and electricity, and builds upon decades of centralized investments in energy-efficient infrastructure.

      This past year, MIT completed a major upgrade of the district energy system whereby the majority of buildings on campus now benefit from the most advanced cogeneration technology for combined heating, cooling, and power delivery. This system generates electrical power that produces 15 to 25% less carbon than the current New England grid. We also have the ability to export power during times when the grid is most stressed, which contributes to the resiliency of local energy systems. On the flip side, any time the grid is a cleaner option, MIT is able to import a higher amount of electricity from the utility by distributing this energy through our centralized system. In fact, it’s important to note that we have the ability to import 100% of our electrical energy from the grid as it becomes cleaner. We anticipate that this will happen as the next major wave of technology innovation unfolds and the abundance of offshore wind and other renewable resources increases as anticipated by the end of this decade. As the grid gets greener, our adaptable district energy system will bring us closer to meeting our decarbonization goals.

      MIT’s ability to adapt its system and use new technologies is crucial right now as we work in collaboration with faculty, students, industry experts, peer institutions, and the cities of Cambridge and Boston to evaluate various strategies, opportunities, and constraints. In terms of evolving into a next-generation district energy system, we are reviewing options such as electric steam boilers and industrial-scale heat pumps, thermal batteries, geothermal exchange, micro-reactors, bio-based fuels, and green hydrogen produced from renewable energy. We are preparing to incorporate the most beneficial technologies into a blueprint that will get us to our 2050 goal.

      Q: What is MIT doing in the near term to reach the carbon-reduction goals of the climate action plan?

      A: In the near term, we are exploring several options, including enabling large-scale renewable energy projects and investing in verified carbon offset projects that reduce, avoid, or sequester carbon. In 2016, MIT joined a power purchase agreement (PPA) partnership that enabled the construction of a 650-acre solar farm in North Carolina and resulted in the early retirement of a nearby coal plant. We’ve documented a huge emissions savings from this, and we’re exploring how to do something similar on a much larger scale with a broader group of partners. As we seek out collaborative opportunities that enable the development of new renewable energy sources, we hope to provide a model for other institutions and organizations, as the original PPA did. Because PPAs accelerate the de-carbonization of regional electricity grids, they can have an enormous and far-reaching impact. We see these partnerships as an important component of achieving net zero emissions on campus as well as accelerating the de-carbonization of regional power grids — a transformation that must take place to reach zero emissions by 2050.

      Other near-term initiatives include enabling community solar power projects in Massachusetts to support the state’s renewable energy goals and provide opportunities for more property owners (municipalities, businesses, homeowners, etc.) to purchase affordable renewable energy. MIT is engaged with three of these projects; one of them is in operation today in Middleton, and the two others are scheduled to be built soon on Cape Cod.

      We’re joining the commonwealth and its cities, its organizations and utility providers on an unprecedented journey — the global transition to a clean energy system. Along the way, everything is going to change as technologies and the grid continue to evolve. Our focus is on both the near term and the future, as we plan a path into the next energy era. More

      MIT J-WAFS announces 2022 seed grant recipients

      by

      The Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) at MIT has awarded eight MIT principal investigators with 2022 J-WAFS seed grants. The grants support innovative MIT research that has the potential to have significant impact on water- and food-related challenges.

      The only program at MIT that is dedicated to water- and food-related research, J-WAFS has offered seed grant funding to MIT principal investigators and their teams for the past eight years. The grants provide up to $75,000 per year, overhead-free, for two years to support new, early-stage research in areas such as water and food security, safety, supply, and sustainability. Past projects have spanned many diverse disciplines, including engineering, science, technology, and business innovation, as well as social science and economics, architecture, and urban planning. 

      Seven new projects led by eight researchers will be supported this year. With funding going to four different MIT departments, the projects address a range of challenges by employing advanced materials, technology innovations, and new approaches to resource management. The new projects aim to remove harmful chemicals from water sources, develop drought monitoring systems for farmers, improve management of the shellfish industry, optimize water purification materials, and more.

      “Climate change, the pandemic, and most recently the war in Ukraine have exacerbated and put a spotlight on the serious challenges facing global water and food systems,” says J-WAFS director John H. Lienhard. He adds, “The proposals chosen this year have the potential to create measurable, real-world impacts in both the water and food sectors.”  

      The 2022 J-WAFS seed grant researchers and their projects are:

      Gang Chen, the Carl Richard Soderberg Professor of Power Engineering in MIT’s Department of Mechanical Engineering, is using sunlight to desalinate water. The use of solar energy for desalination is not a new idea, particularly solar thermal evaporation methods. However, the solar thermal evaporation process has an overall low efficiency because it relies on breaking hydrogen bonds among individual water molecules, which is very energy-intensive. Chen and his lab recently discovered a photomolecular effect that dramatically lowers the energy required for desalination. 

      The bonds among water molecules inside a water cluster in liquid water are mostly hydrogen bonds. Chen discovered that a photon with energy larger than the bonding energy between the water cluster and the remaining water liquids can cleave off the water cluster at the water-air interface, colliding with air molecules and disintegrating into 60 or even more individual water molecules. This effect has the potential to significantly boost clean water production via new desalination technology that produces a photomolecular evaporation rate that exceeds pure solar thermal evaporation by at least ten-fold. 

      John E. Fernández is the director of the MIT Environmental Solutions Initiative (ESI) and a professor in the Department of Architecture, and also affiliated with the Department of Urban Studies and Planning. Fernández is working with Scott D. Odell, a postdoc in the ESI, to better understand the impacts of mining and climate change in water-stressed regions of Chile.

      The country of Chile is one of the world’s largest exporters of both agricultural and mineral products; however, little research has been done on climate change effects at the intersection of these two sectors. Fernández and Odell will explore how desalination is being deployed by the mining industry to relieve pressure on continental water supplies in Chile, and with what effect. They will also research how climate change and mining intersect to affect Andean glaciers and agricultural communities dependent upon them. The researchers intend for this work to inform policies to reduce social and environmental harms from mining, desalination, and climate change.

      Ariel L. Furst is the Raymond (1921) and Helen St. Laurent Career Development Professor of Chemical Engineering at MIT. Her 2022 J-WAFS seed grant project seeks to effectively remove dangerous and long-lasting chemicals from water supplies and other environmental areas. 

      Perfluorooctanoic acid (PFOA), a component of Teflon, is a member of a group of chemicals known as per- and polyfluoroalkyl substances (PFAS). These human-made chemicals have been extensively used in consumer products like nonstick cooking pans. Exceptionally high levels of PFOA have been measured in water sources near manufacturing sites, which is problematic as these chemicals do not readily degrade in our bodies or the environment. The majority of humans have detectable levels of PFAS in their blood, which can lead to significant health issues including cancer, liver damage, and thyroid effects, as well as developmental effects in infants. Current remediation methods are limited to inefficient capture and are mostly confined to laboratory settings. Furst’s proposed method utilizes low-energy, scaffolded enzyme materials to move beyond simple capture to degrade these hazardous pollutants.

      Heather J. Kulik is an associate professor in the Department of Chemical Engineering at MIT who is developing novel computational strategies to identify optimal materials for purifying water. Water treatment requires purification by selectively separating small ions from water. However, human-made, scalable materials for water purification and desalination are often not stable in typical operating conditions and lack precision pores for good separation. 

      Metal-organic frameworks (MOFs) are promising materials for water purification because their pores can be tailored to have precise shapes and chemical makeup for selective ion affinity. Yet few MOFs have been assessed for their properties relevant to water purification. Kulik plans to use virtual high-throughput screening accelerated by machine learning models and molecular simulation to accelerate discovery of MOFs. Specifically, Kulik will be looking for MOFs with ultra-stable structures in water that do not break down at certain temperatures. 

      Gregory C. Rutledge is the Lammot du Pont Professor of Chemical Engineering at MIT. He is leading a project that will explore how to better separate oils from water. This is an important problem to solve given that industry-generated oil-contaminated water is a major source of pollution to the environment.

      Emulsified oils are particularly challenging to remove from water due to their small droplet sizes and long settling times. Microfiltration is an attractive technology for the removal of emulsified oils, but its major drawback is fouling, or the accumulation of unwanted material on solid surfaces. Rutledge will examine the mechanism of separation behind liquid-infused membranes (LIMs) in which an infused liquid coats the surface and pores of the membrane, preventing fouling. Robustness of the LIM technology for removal of different types of emulsified oils and oil mixtures will be evaluated. César Terrer is an assistant professor in the Department of Civil and Environmental Engineering whose J-WAFS project seeks to answer the question: How can satellite images be used to provide a high-resolution drought monitoring system for farmers? 

      Drought is recognized as one of the world’s most pressing issues, with direct impacts on vegetation that threaten water resources and food production globally. However, assessing and monitoring the impact of droughts on vegetation is extremely challenging as plants’ sensitivity to lack of water varies across species and ecosystems. Terrer will leverage a new generation of remote sensing satellites to provide high-resolution assessments of plant water stress at regional to global scales. The aim is to provide a plant drought monitoring product with farmland-specific services for water and socioeconomic management.

      Michael Triantafyllou is the Henry L. and Grace Doherty Professor in Ocean Science and Engineering in the Department of Mechanical Engineering. He is developing a web-based system for natural resources management that will deploy geospatial analysis, visualization, and reporting to better manage and facilitate aquaculture data.  By providing value to commercial fisheries’ permit holders who employ significant numbers of people and also to recreational shellfish permit holders who contribute to local economies, the project has attracted support from the Massachusetts Division of Marine Fisheries as well as a number of local resource management departments.

      Massachusetts shell fisheries generated roughly $339 million in 2020, accounting for 17 percent of U.S. East Coast production. Managing such a large industry is a time-consuming process, given there are thousands of acres of coastal areas grouped within over 800 classified shellfish growing areas. Extreme climate events present additional challenges. Triantafyllou’s research will help efforts to enforce environmental regulations, support habitat restoration efforts, and prevent shellfish-related food safety issues. More

      Strengthening students’ knowledge and experience in climate and sustainability

      by

      Tackling the climate crisis is central to MIT. Critical to this mission is harnessing the innovation, passion, and expertise of MIT’s talented students, from a variety of disciplines and backgrounds. To help raise this student involvement to the next level, the MIT Climate and Sustainability Consortium (MCSC) recently launched a program that will engage MIT undergraduates in a unique, year-long, interdisciplinary experience both developing and implementing climate and sustainability research projects.

      The MCSC Climate and Sustainability Scholars Program is a way for students to dive deeply and directly into climate and sustainability research, strengthen their skill sets in a variety of climate and sustainability-related areas, build their networks, and continue to embrace and grow their passion.The MCSC Climate and Sustainability Scholars Program is representative of MIT’s ambitious and bold initiatives on climate and sustainability — bringing together faculty and students across MIT to collaborate with industry on developing climate and sustainability solutions in the context of undergraduate education and research.

      The program, open to rising juniors and seniors from all majors and departments, is inspired by MIT’s SuperUROP program. Students will enroll in a year-long class while simultaneously engaging in research. Research projects will be climate- and sustainability-focused and can be on or off campus. The course will be initially facilitated by Desiree Plata, the Gilbert W. Winslow Career Development Professor in Civil and Environmental Engineering, and Elsa Olivetti, the Esther and Harold E. Edgerton Associate Professor in Materials Science and Engineering and MCSC co-director.“Climate and sustainability challenges face real barriers in science, technology, policy, and beyond,” says Plata, who also serves on the MCSC’s Faculty Steering Committee. “We need to motivate an all-hands effort to bring MIT talent to bear on these challenges, and we need to give our students the tools to make tangible benefits within and between their disciplines. This was our goal in designing the MCSC Scholars Program, and it’s what I’m most excited about.”

      The Climate and Sustainability Scholars Program has relevance across all five schools, and the number of places the course is cross-listed continues to grow. As is the broader goal of the MCSC, the Climate and Sustainability Scholars Program aims to amplify and extend MIT’s expertise — through engaging students of all backgrounds and majors, bringing in faculty mentors and instructors from around the Institute, and identifying research opportunities and principal investigators that span disciplines. The student cohort model will also build off of the successful community-building endeavors by the MIT Energy Initiative and Environmental Solutions Initiative, among others, to bring students with similar interests together into an interdisciplinary, problem-solving space.The program’s fall semester will focus on key climate and sustainability topics, such as decarbonization strategies, policy, environmental justice, and quantitative methods for evaluating social and environmental impacts, and humanities-based communication of climate topics, all while students engage in research. Students will simultaneously develop project proposals, participate in a project through MIT’s Undergraduate Research Opportunities Program, and communicate their work using written and oral media. The spring semester’s course will focus on research and experiential activities, and help students communicate their outputs in entrepreneurial or policy activities that would enable the research outcomes to be rapidly scaled for impact.Throughout the program, students will engage with their research mentors, additional mentors drawn from MCSC-affiliated faculty, postdoctoral Impact Fellows, and graduate students — and there will also be opportunities for interaction with representatives of MCSC member companies.“Providing opportunities for students to sharpen the skills and knowledge needed to pioneer solutions for climate change mitigation and adaptation is critical,” says Olivetti. “We are excited that the Climate and Sustainability Scholars Program can contribute to that important mission.” More
