The Covenant of Mayors for Climate and Energy is open to all local authorities democratically constituted with/by elected representatives, whatever their size and whatever the stage of implementation of their energy and climate policies.
Neighbouring small and medium-sized local authorities can also, under certain conditions, decide to join as a group of signatories.
The commitments for Covenant signatories are linked to the EU's climate and energy policy framework: the 2020 climate and energy package for signatories who have joined between 2008 and 2015 and the 2030 climate and energy framework as well as the EU Strategy on Adaptation to Climate Change for signatories joining after 2015.
Covenant signatories commit to adopting an integrated approach to climate change mitigation and adaptation. They are required to develop, within the first two years of adhesion, a Sustainable Energy and Climate Action Plan with the aims of cutting CO2 emissions by at least 40% by 2030 and increasing resilience to climate change.
