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
GLOBAL METHANE ASSESSMENT
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.
Reducing human-caused methane emissions is one of the most cost-effective strategies to rapidly reduce the rate of warming and contribute significantly to global efforts to limit temperature rise...

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.

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.
Request national planning support by writing to firstname.lastname@example.org.
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.
Request policy and regulatory support by writing to email@example.com.
Methane Country Projections
CCAC Methane Country Projections are stand‐alone briefings designed as tools for communication and advocacy, as well as discussion starters in the context of the Global Methane Pledge. They are designed to show the scale of potential reductions and high priority targets in each country, and to help guide strategic decision‐making by Global Methane Pledge partners. The data used for Country Projections is taken from international data used in the 2021 Global Methane Assessment, not from national inventories. This allows the Country Projections to be internally consistent and comparable between countries, regions and global assessments. The country projections do not replace nationally generated data or assessments. The projections are made available to ODA‐eligible countries, and upon request, beyond. They will not be made public unless the respective country wishes to do so.
