18 May 2012 Coal is without question our dirtiest fuel source: When burned, it dumps toxins like mercury and nitrogen oxides into the air and packs an outsize punch when it comes to carbon emissions. Since America has a lot of it, though, we’ve tended to use a lot: Historically, around half our electricity has been generated by coal combustion plants. But as a result of sustained anti-coal activism, low prices for natural gas, and new EPA regulations on power plant emissions, Americans are using a lot less coal than we used to, and the future of the sooty stuff in this country is looking dim. So the U.S. coal industry is pinning its hopes on China. While historically most of our exported coal has gone to Europe, U.S. exports to China increased 176 percent between 2009 and 2010, and that number is likely to keep rising as the Asian market for coal continues to expand. The prospect of shipping coal across the Pacific is even more appealing considering that Western states like Wyoming and Montana have vast coal reserves in the Powder River Basin, one of the largest coal deposits in the world. But while the incentives to drastically scale up Western-mined, Asia-bound coal exports exist, the infrastructure to do so does not — at least, not yet. Coal mining companies are hoping to change that by building up to six coal export terminals in the Pacific Northwest — three apiece in Washington and Oregon — with the combined capacity to ship around 150 million short tons of coal to Asia each year. These new plans would more than double 107 million short tons of coal the U.S. exported in 2011. But good news for the coal industry is bad news for the climate, and whether Powder Basin coal is burned here or abroad, it’ll add the same amount of greenhouse gas emissions to an already-warming atmosphere. In 2007, Powder Basin coal alone was responsible for an estimated 900 million tons of carbon dioxide, around 13 percent of the U.S. total; Eric de Place at the Sightline Institute crunched the numbers and found that the coal shipped by just two of the proposed terminals would be responsible for more annual emissions than the tar sands oil carried by the Keystone pipeline. As Bryan Walsh points out, many industrialized countries have cut their own carbon footprint by exporting carbon-intensive fuels to be burned elsewhere, essentially employing an accounting trick rather than actually reducing global emissions. But climate activists aren’t going to let us get away with it if they can help it: Having largely succeeded in stopping Americans from burning coal, activists are trying to make sure no one else burns it either. And, as with Keystone, they’re seeking to accomplish their climate goals by blocking fossil fuel infrastructure from being built. […] Matt Yglesias thinks they have a decent shot, explaining that “the fact that the vast coal reserves of the American heartland need to pass through the relatively narrow bottleneck of the generally progressive Pacific Northwest gives environmentalists one of their best available opportunities to curb carbon dioxide emissions in the absence of any meaningful progress toward a national or global framework.” But if the coal industry starts to get worried, it’s hard to imagine Republicans and coal state Democrats won’t gleefully seize the opportunity to denounce the protesters as tree-hugging job killers.
