Europe To Cut Carbon Emissions By 40 % By 2030 compared with 1990 levels, the toughest climate change target of any region in the world, and will produce 27 percent of its energy from renewable sources by then, announced the European Union, reports Fiona Harvey at the UK Guardian. Doing so will cost less than 1% of its economy. Green groups protested that the cuts are not enough to meaninfully address climate change, and will cost Europe in terms of fewer green jobs, and shortened lives from pollution. No national targets for investing in clean energy makes it unclear how the overall targets will be reached.
