Benchmarks of Excellence are relevant examples of initiatives which Covenant signatories, Coordinators and Supporters feel particularly proud of, and moreover endorse as useful actions for other local authorities, provinces, regions or networks to replicate.

The European Commission defines “Covenant Coordinators” as those public administrations which provide strategic guidance, financial and technical support to municipalities signing up to the Covenant of Mayors but lacking necessary skills and/or resources to fulfil their requirements. Covenant Coordinators are sub-national decentralized authorities - including provinces, regions and public groupings of municipalities - and national public bodies as national energy agencies for instance.

The Covenant of Mayors Office (CoMO), established and funded by the European Commission, is responsible for the coordination and daily management of the initiative. It provides signatories with administrative support and technical guidance, facilitates networking between Covenant stakeholders and ensures the promotion of their activities.

The European Commission defines “Covenant Supporters” as European, national and regional networks and associations of local authorities which leverage their lobbying, communication and networking activities to promote the Covenant of Mayors initiative and support the commitments of its signatories.
