Reuters reports that China has just approved three new plants in its western provinces that would turn coal into synthetic natural gas. The idea is that this gas would then be shipped to population centers in the east, where it would burn much more cleanly in power plants and detoxify the air in cities like Beijing.
Except there's a huge catch: The coal-to-gas (CTG) plants themselves are highly energy-intensive and can create far more CO2 overall than coal alone. It's basically swapping less smog for more climate change. China currently has three CTG plants operating, four under construction, three newly approved, and plans for another 17 in preparation. If even a fraction are built — a big "if" — that could have a sizeable impact on global warming.
