The Climate and Clean Air Coalition (CCAC) is a voluntary partnership of over 190 governments, intergovernmental organizations, and non-governmental organizations founded in 2012, and convened within UNEP.  

Collectively and individually, partners who join the Climate and Clean Air Coalition are working 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.

CCAC aims to connect ambitious agenda-setting with targeted mitigation action within countries and sectors. Robust science and analysis underpin its efforts. CCAC supports action to reduce short-lived climate pollutants in more than 90 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.

Through the CCAC Trust Fund, CCAC funds projects in developing countries to enable actions that deliver climate, air quality and development benefits. Its project funding is split between national policy development and implementation of mitigation measures.

CCAC provides secretariat functions of the Global Methane Pledge, and the coordination group of the Lowering Organic Waste Methane Initiative is housed in CCAC.
