China’s flagship coal-to-gas pilot project is already breaking national standards on air and water pollution, according to an on-the-ground investigation by Greenpeace China. China is considering more than 50 new coal to gas projects in a move partially designed to reduce air pollution. The process is extremely carbon intensive and recent analysis suggests the projects undermine a recent China-US agreement on tackling climate change. Domestically the plans have sparked concerns about water use and local pollution.
