China's emissions grew by just half a percent in 2025, the slowest rate in years, as coal power fell for the first time in a decade. But heavy industries like steel, cement, and chemicals still make up fourteen percent of total national emissions. A new report says China must now focus on cleaning up these hard sectors, using green hydrogen and clean electricity. Mobilising two point four trillion US dollars in green investment over five years could cut emissions by one point six billion metric tons by 2030.
