To position cities as true climate leaders and to demonstrate that local action can have a significant global impact, the Global Covenant of Mayors’ participants engage in a four-phase process to fight climate change. The four phases are:
Within three years from a city committing to be part of the Global Covenant of Mayors for Climate and Energy a city is required to meet full compliance through having completed both mitigation (A) and adaptation compliance (B). This includes:
- GPC Inventory (which is made up of a minimum three sectors, covering the appropriate scopes and with a minimum of 3 GHGs) and the supportive activity data,
- an emissions reduction target,
- a hazards report and vulnerability assessment
- a climate action plan and climate adaptation plan.
Timeline: The compliance elements can be completed sooner than three years and can be in the form of combined documents. Entering the required information in the provided Carbonn reporting tools or worksheets is the most effective way of meeting compliance.
Reporting: ICLEI uses the CDP or Carbonn climate registry for reporting while using tools like CIRIS, Clearpath both based on the GPC
Reporting frequency: A complete updated inventory shall be required every three years, and the inventory year may be no more than three years prior to the reporting year.
