China, the world's top greenhouse gas emitter, is often chided for its carbon-belching, Dickensian-looking coal plants. But it is working to clean up its coal power.
This was seen for example in a coal market survey report by analysts at CITIC Futures, who in February visited eight coal mines in Inner Mongolia, Shaanxi and Shanxi. According to statistics from the Coal Industry Association, the raw coal washing rate in China has decreased from the peak of 74.1% in 2020 to 69.7% in 2022.
