Fig. 3: Distribution of biomass feedstocks and negative emission potential under ‘Sustainable Technical’ scenario.

a–d The distribution of agricultural residues, forestry residues, grass residues, and energy crops on a 0.5° × 0.5° grid. China is divided into six regions: black for North China, red for Northeast China, orange for East China, yellow for Central and South China, green for Southwest China, and blue for Northwest China. Hongkong, Macau, and Taiwan were not included in our analysis. e–h Available biomass feedstock in the six regions. i Negative emission potential at a 0.5° × 0.5° grid. j Negative emission potential in the six regions. Source data are provided as a Source data file. The shapefile of national and provincial boundaries is quoted from the National Catalogue Service For Geographic Information, accessible at www.webmap.cn.
