Europe's major urban areas are estimated to generate some 20% of global greenhouse gas emissions.

The International Panel on Climate Change, the IPCC, and the European Commission have concluded that a reduction of 80% on 1990 emission levels, by 2050, will be required if average global temperature rise is to be contained to 2 degrees centigrade.
