(Unfortunately the German coal industry is exempt from requirements under the EU internal emission trading system. Claudia Kemfert, an energy professor at the German Institute for Economic Research in Berlin said, "For all its support for a clean environment and the Kyoto Protocol, the cabinet decision is very disappointing." Which is a bit of an understatement.)
