Who produces the most coal in the world?
Who produces the most coal in the world? China How effective are coal scrubbers? Using data from 1997-2012 of 995 coal-burning power plants, we examine the effectiveness of scrubber installation in reducing SO2 and NOx emissions. These final two results are corroborated by a matching algorithm, which finds scrubbers cause SO2 and NOx emissions decline […]
