At COP26 in November 2021, over 100 countries joined the Global Methane Pledge (GMP), committing to collectively cut global anthropogenic methane emissions by at least 30% by 2030 from 2020 levels. Achieving this goal would put the world on a path to limit warming to 1.5ºC. 

All Global Methane Pledge participants are encouraged to develop or update a methane reduction action plan by COP27. These plans can help countries leverage emerging data and techniques to enhance their Paris Agreement methane emissions inventories; identify compelling abatement strategies; and define methane-related policies, programs, and project proposals. These plans can also help to match governments with technical assistance from GMP partners. 

To support the Global Methane Pledge, the Climate and Clean Air Coalition (CCAC) will work with participating countries to identify resources to support methane mitigation. The CCAC stands ready to meet one-on-one with countries to discuss priorities and needs and help develop the most efficient methane mitigation strategies to realize the goals of the Pledge.

Tools for methane mitigation


The CCAC-UN Environment Programme Global Methane Assessment shows that human-caused methane emissions can be reduced by up to 45% this decade and identifies measures to target emissions cost effectively and with immediate benefits to society. Get the assessment and web tool below.



Most human-caused methane emissions come from just three sectors: agriculture (40% of global anthropogenic methane emissions), fossil fuels (35%), and waste (20%). Agricultural emissions include emissions from livestock enteric fermentation, livestock manure, and rice cultivation. Waste emissions include solid waste and wastewater.

Sector-focused expert assistance

The CCAC can match governments with external experts on methane mitigation in the Agriculture, Fossil Fuel and Waste sectors. Experts are able to provide guidance on technological options, mitigation measures, funding opportunities, application of measurement tools, and policy development.

National Planning Support

The CCAC supports developing countries to develop national plans that integrate climate and clean air objectives through actions to reduce methane and other short-lived climate pollutants. This integrated planning approach provides structure to the national planning process, while remaining flexible enough to accommodate for the unique context and challenges in each country.  

The CCAC is accepting new requests for support at all stages of the national planning process, for activities including emissions inventories, policy and mitigation measure assessments, action plan design, and Monitoring, Reporting & Verification (MRV). Funding is available to ODA-eligible countries.

Policy and regulatory support

The CCAC supports policy design and implementation in developing countries through targeted activities such as regulatory analysis, cost-benefit analysis, and peer-to-peer exchanges. Funding is available to ODA-eligible countries.
