March 2007 set the date for the “20-20-20” targets in the European Union: 20% less carbon emissions, 20% more renewable energy production and 20% more energy efficiency. Five years and an economic crisis later, and with only eight years left to reach 2020, a recent report states we will fall short of some of these objectives. In the midst of this grim scenario, something stands out: the Covenant of Mayors, a group of more than 4250 European municipalities voluntarily committing to surpassing EU’s “20-20-20” targets”. Can they do it? They can, but most of them probably will not.
