BERLIN- Germany wants to ensure that its plan to cancel emissions certificates linked to coal power stations that are due to be shuttered doesn't undermine the European Union's emissions trading system, it said in a draft law seen by Reuters.

The government proposal also stipulates that the German finance and economy ministries will work with at least two independent appraisers to determine how many certificates should be cancelled.
