The document discusses the roles of coordinators and supporters in promoting and implementing the Covenant of Mayors initiative. It notes that the initiative has seen unprecedented success with over 5,000 signatories committing to reduce CO2 emissions by around 30%. Coordinators and supporters play key roles in promoting the initiative, providing technical support to signatories, and facilitating multi-stakeholder coordination. They assist signatories with activities like developing emissions inventories, energy action plans, training, and monitoring progress. Many coordinators and supporters also provide direct or indirect financial support for plan development and implementation.
