Commit

Any city or town in the world may commit to the Compact of Mayors—regardless of size or location. A city has up to three years to meet a series of requirements and fully comply, culminating in the creation of a full climate action and adaptation plan. Many cities have already completed some of the phases and/or will be compliant in fewer than three years.

Download the full guide to compliance for the Compact of Mayors.

To position cities as true climate leaders and to demonstrate that local action can have a significant global impact, the Compact of Mayors’ participants engage in a multi-phase process to fight climate change.


  • Phase 1

  • Phase 2

  • Phase 3

  • Phase 4

  • Compliant

  • Phase 1: Commitment

    Register Commitment A mayor may register on either of the Compact’s partner reporting platforms—carbonn Climate Registry or CDP—or email a letter of intent to info@compactofmayors.org. As part of their commitment, cities agree to perform a series of key activities within three years from the date of their commitment. Following this submission, a city will be contacted by the Compact support team and will receive an official “Commitment” badge to display on local digital or print materials.
    Step 1:
    Mitigation
    • Address GHG emissions reduction
    • Measure emissions inventory using a consistent and robust standard
    • Set appropriate targets for the future
    • Develop climate action plans to deliver on city targets
    Step 2:
    Adaptation
    • Address the impacts of climate change
    • Identify climate hazards
    • Assess vulnerabilities
    • Develop climate adaptation plans

    Phase 2: Inventory

    Take Inventory Within one year of its commitment, a city must assess the current impacts of climate change in his/her city. To do so, the city must: (1) Build and complete an overall greenhouse gas emissions inventory utilizing Compact standard; (2) Identify climate risks; and (3) Report on both via the CDP or carbonn questionnaires.
    Step 1:
    Mitigation
    Cities must:
    • Measure community emissions inventory using a consistent and robust standard.
    • Report in chosen platform.
     
    Step 2:
    Adaptation
    Cities must:
    • Identify climate hazards
    • Report in chosen platform

    Phase 3: Target

    Create Targets and Establish A System of Measurement Within two years, the registered city must update its GHG inventory to include a breakdown of emissions by sources and sectors; set a target to reduce its GHG emissions; conduct a “climate change vulnerability assessment” using the Compact standard; and report in its chosen platform.
    Step 1:
    Mitigation
    • Update GHG inventory to include a breakdown of emissions by sources and sectors.
    • Set GHG reduction target.
    • Report in chosen platform.
    Step 2:
    Adaptation
    • Assess climate vulnerabilities using Compact standard.
    • Report in chosen platform.

    Phase 4: Plan

    Establish An Action Plan Within three years, a city’s strategic action plan must show how it will deliver on its commitment to reduce greenhouse gas emissions and adapt to climate change.
    Step 1:
    Mitigation
    • Develop climate action plan demonstrating how city will deliver on its commitment to reduce greenhouse gas emissions.
    • Report in chosen platform.
    Step 2:
    Adaptation
    • Develop climate resilience plan demonstrating how city will deliver on its commitment to adapt to the impacts of climate change.
    • Report in chosen platform.

    Upon completing the Compact of Mayors' compliance process, a city will be eligible to receive a "Compliant" badge on an annual basis to signify their commitment and progress.
