Short summary
China, the world’s largest methane emitter, faces challenges in accurately tracking. CHN-CH4, a map of anthropogenic methane emissions was created by combining satellite data, national statistics, and climate guidelines. Over 30 years, China emitted about 1157 Tg of methane, peaking in the 2010s. Shanxi province had the highest emissions. CHN-CH4 helps improve tracking, informs global climate models, and strengthens collaboration between science and policy to combat climate change.
