The Climate and Clean Air Trust Fund, established in 2012, is administered by UN Environment (UNEP). The Trust Fund supports projects approved by the Coalition, activities of the Coalition Secretariat, and administrative support for Coalition meetings. 


The Trust Fund has to date raised over US$ 86 million from the following countries: Canada, Norway, United States, Japan, Sweden, Switzerland, European Commission, Denmark, Netherlands, Germany, Italy, France, Walloon Government of Belgium, Australia, and Finland.

Allocation of funds

Allocated funds are approved by the Coalition's Working Group, following a process outlined in the “CCAC Guidelins on Initiative Functioning and Funding Process”. The process consists of two key steps: the submission of concept notes for review by the Steering Committee and approval from the Working Group; and – for approved concept notes – the finalisation of full proposals and budgets for approval from the Steering Committee with support of the Coalition Secretariat.

The fund has supported activities in each of the Coalition's 11 initiatives, targeting transformational change in the sectors of household energy, cooling, bricks production, oil and gas production, agriculture, transport, solid waste, and national and local planning.  


Contribute to the Coalition

The Coalition's Initiatives are important vehicles for inspiring and supporting actions to reduce short-lived climate pollutants. Activities under the Initiatives can be sponsored fully or partially through the Trust Fund, or be supported entirely by external funds.

Contributions in the form of expertise, work or resources allocated to the Coalition Trust fund are welcome. 

If you would like to support actions to reduce short-lived climate pollutants or receive more information about funding for the Coalition, please contact the Coalition secretariat at
