Illustration Signatories

The fight against climate change will be won or lost in urban areas. A vast majority of the European population lives and works in cities, consuming an estimated 80% of the energy used in the EU. Local administrations, as the closest government level to citizens are ideally placed to address climate issues in a comprehensive manner. More and more cities are thus deciding to take up the challenge, as shown by the growing number of Covenant of Mayors signatories.

Signatories represent cities that vary in size from small villages to major metropolitan areas such as London or Paris. Within a year following their signature, Covenant signatories commit to implement Sustainable Energy Action Plans on their territory, with the aim of cutting CO2 emissions by at least 20% by 2020.
