Climate

Emissions trading is the European Union’s flagship measure for tackling climate change, and it is failing badly. In theory it provides a cheap and efficient means to limit greenhouse gas reductions within an ever-tightening cap, but in practice it has rewarded major polluters with windfall profits, while undermining efforts to reduce pollution and achieve a more equitable and sustainable economy. The third phase of the scheme, beginning in 2013, is supposed to rectify the “teething problems” that have led to the failures to date.
