Climate and Clean Air Coalition (CCAC)

In Energy

Founded in 2012, and convened within UNEP, The Climate and Clean Air Coalition (CCAC) is a voluntary partnership of more than 160 governments, intergovernmental organizations, and non-governmental organizations.  

The CCAC works to reduce powerful but short-lived climate pollutants (SLCPs) – methane, black carbon, hydrofluorocarbons (HFCs), and tropospheric ozone – that drive both climate change and air pollution. It aims to connect ambitious agenda setting with targeted mitigation action within countries and sectors. Robust science and analysis underpin its efforts. It supports action to reduce short-lived climate pollutants in more than 70 countries through the funding of projects and the individual actions of its partners.

The partnership works to reduce global warming in the near-term to achieve Paris Agreement goals and support economic development, improved health, and environmental and food security benefits.

The CCAC funds projects that implement methane policy and mitigation measures around the world. It also provides secretariat functions of the Global Methane Pledge and the coordination group of Lowering Organic Waste Methane Initiative is housed in CCAC.

Methane Roadmap Action Programme (M-RAP) 

 Countries signing the Global Methane Pledge (GMP) agree to take voluntary national action to contribute to a collective effort to reduce global methane emissions by at least 30 per cent below 2020 levels by 2030. Countries that sign the GMP are also encouraged to develop or update Methane Action Plans.  



The Climate and Clean Air Coalition, as the first point-of-call for GMP countries, has launched the Methane Roadmap Action Programme (M-RAP) to support the development and implementation of transparent national methane roadmaps. National planning for methane abatement supports coordinated and accelerated progress on identification and development of relevant methane targeted measures and supporting policies, including in the context of NDCs revision.



All GMP countries eligible to receive official development assistance can receive CCAC funding to develop their National Methane Roadmap or Action Plan.

Global Methane Assessment 

Published in 2021 by the Climate and Clean Air Coalition and UNEP, the Global Methane Assessment reveals that human-caused methane emissions can be reduced by up to 45 per cent this decade.

Reducing human-caused methane emissions is one of the most cost-effective strategies to contribute significantly to global efforts to limit temperature rise to 1.5° C. Available targeted methane measures, together with additional measures that contribute to priority development goals, can simultaneously reduce human-caused methane emissions by as much as 45 per cent, or 180 million tonnes a year by 2030.

This would avoid nearly 0.3° C of global warming by the 2040s and complement all long-term climate change mitigation efforts. It would also prevent 255 000 premature deaths, 775 000 asthma-related hospital visits, 73 billion hours of lost labour from extreme heat, and 26 million tonnes of crop losses globally every year.

Reducing human-caused methane emissions is one of the fastest, most cost-effective strategies to reduce the rate of warming and contribute to global efforts to limit temperature rise to 1.5°C. Global action to reduce methane emissions has additional benefits for human health, food security and ecosystems, as it can curb the formation of tropospheric ozone, an air pollutant with multiple harmful impacts.  

As human-caused methane emissions continue to increase, there are more reasons than ever to reduce methane emissions this decade. The Climate and Clean Air Coalition and UN Environment Programme's Global Methane Assessment shows that we have the technologies and policy frameworks to do so cost effectively and with immediate benefits to society.

What are Short-Lived Climate Pollutants?

Short-lived climate pollutants - including black carbon, methane, hydrofluorocarbons, and tropospheric ozone - are powerful climate forcers with global warming potentials many times that of carbon dioxide. These pollutants also significantly impact air quality, food, water and economic security for much of the world, both directly through their negative effects on public health, agriculture and ecosystems, and indirectly through their impact on the climate.

How can we cut emissions?

The measures and technologies to reduce short-lived climate pollutants are available today and are practical, technically feasible, and cost-effective. Putting them in place can bring immediate climate benefits, help achieve many global sustainable development goals (SDGs), and improve the health and livelihoods of millions.
