Thus The Wall Street Journal today. “America’s dirty coal is being embraced in one of the cleanest energy markets—the European Union,” elaborates the newspaper. “The EU imported 47.2 million tons of US coal last year, up from 13.6 million tons in 2003.” Surprise, surprise. Coal mining has been in trouble in the States for years, but its business with the rest of the world is doing well. Much of the coal goes to Britain, where it is used to produce electricity. Power plants using natural gas are facing ruin on account of the rising price of gas, and the Ukraine crisis only adds to their demise. In the States, it is the other way around, whence the brisk export of coal. American environmentalists say that exporting coal is like sending greenhouse-gas emissions abroad, but few are listening to them. In fact, that is the idea. The only trouble is that the earth’s atmosphere has no borders.
