Abstract
The rapid deployment of renewable energy creates urgent trade-offs with biodiversity conservation. The uneven distribution of renewable energy potential and biodiversity creates a critical governance challenge: at which administrative level should goal setting and spatial planning decisions be set to best mitigate these conflicts? Here we model the expansion of solar and wind energy in China through 2060 to reach its carbon neutrality goal, to compare a centralized national planning scenario against the current provincial (more decentralized) planning approach. We find that national sitings’ spatial conflict with richness-based conservation priorities is 4–7% less and overlaps 11–33% fewer species on average than the provincial planning. However, these gains are offset by greater conflicts with functional diversity and with open or dry biomes, including associated species such as the endangered marbled polecat (Vormela peregusna). By contrast, decentralized planning disproportionately overlapped more with the habitats of small-ranged forest species. Such divergence reveals the limitations of any single governance level in addressing these trade-offs, showing the imperative for integrated, multilevel siting frameworks. Effectively meeting dual climate and biodiversity targets requires strategies that synthesize strengths across administrative scales.

Province map reproduced from Tianditu (map approval number GS(2024)0605; www.tianditu.gov.cn). Silhouettes from PhyloPic under a Creative Commons license: frog by Steven Traver and leopard by Margot Michaud (CC0 1.0); lizard by Vijay Karthick and bird by Xgirouxb (PDM 1.0).

Extended Data Fig. 3 Area of habitat (AOH) of individual species overlapped by existing energy sites.
Bar graphs showed the top 5 species of concern (IUCN-listed as threatened or endemic to China) most subject to existing solar and wind energy, ranked by the percentage (%) of AOH in China overlapped (orange) and the absolute (km2) AOH overlapped (blue). Each species is denoted by its scientific name and the corresponding taxon icon. Bars with shade indicate small-ranged species (AOH < 10,000 km2). See Supplementary Table 9 and 10 for additional information.
