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.

Signatory cities vary in size from small villages to major metropolitan areas such as London or Paris.

The commitments for Covenant Signatories are linked to the European Union’s Climate and energy policy framework. These include the European Union’s climate and energy package for 2020 for signatories who have joined between 2008 and 2015 and the European Union’s 2030 climate and energy framework as well as the EU Strategy on Adaptation to Climate Change for signatories joining after 2015.

As of October 2015, Covenant signatories commit to adopting an integrated approach to climate change mitigation and adaptation. They are required to develop Sustainable Energy and Climate Action Plans with the aims of cutting CO2 emissions by at least 40% by 2030 and increasing resilience to climate change within the first two years of adhesion.
