The Climate and Clean Air CoalitionĀ to Reduce Short-Lived Climate Pollutants

The Climate and Clean Air Coalition (CCAC) is a voluntary partnership of governments, intergovernmental organizations, businesses, scientific institutions, and civil society organizations committed to improving air quality and protecting the climate through actions to reduce short-lived climate pollutants.

IGSD is a non-state partner of the CCAC.


The Coalition takes action through its Hubs, which are partner-led and designed to promote transformative action in sectors or as cross-cutting efforts to reduce methane, black carbon, and HFCs.


The CCAC focuses on eight sectors to identify the most cost-efficient and practical pathways to reduce emissions. They work closely with relevant communities, industry representatives, NGOs, and policymakers to support targeted improvements to technology, best practice, and policies.

  • Heavy-Duty Vehicles: This initiative works to reduce the climate and health impacts of black carbon and particulate matter (PM) emissions in the transport sector.
  • Oil and Gas: This initiative seeks to promote significant reductions in methane and black carbon emissions from the oil and gas sector and specifically: 45% emissions reductions in methane emissions overestimated 2015 levels by 2025 and 60-75% reductions by 2030.
  • Waste: This initiative addresses methane, black carbon, and other air pollutant emissions from the municipal solid waste sector through its work with cities and national governments.
  • Bricks: This initiative addresses emissions of black carbon and other pollutants from brick production to reduce the harmful climate, air pollution, economic, and social impacts from this sector.
  • HFCs: This initiative targets governments and the private sector to address rapidly growing HFC emissions, which could account for as much as 19% of carbon dioxide (CO2) emissions by 2050, if left unchecked.
  • Household Energy: This initiative seeks to reduce short-lived climate pollutants from domestic cooking, heating, and lighting. Household cooking and domestic heating are major sources of significant contributors to global climate change like carbon dioxide, and a number of short-lived climate pollutants (SLCPs) including methane and black carbon. Residential solid fuel burning is responsible for 25% of all black carbon emissions. 84% of these homes are in developing countries.
  • Agriculture: This initiative helps countries identify increasingly ambitious actions, policies, and targets across the food system. Guided by a priority to enhance food security and livelihoods, the CCAC demonstrates solutions to reduce short-lived climate pollutants that deliver quick benefits for the climate and air quality.
  • Efficient Cooling: By combining efforts to improve energy efficiency in the cooling sector with the phase-down of HFC refrigerants under the Kigali Amendment to the Montreal Protocol, this initiative aims to double the climate benefits of the HFC phasedown alone.


The CCAC carries out work across sectors to accelerate emissions reductions for all short-lived climate pollutants. Changes in policies and practices in these areas can affect change across a wide range of polluting activities.

  • Supporting National Action and Planning (SNAP) on Short-Lived Climate Pollutants: Measures to mitigate SLCPs have been assessed at a global and regional level and now need to be incorporated into national policies and actions. This initiative has developed a program to support National Action Plans for SLCPs, including national inventory development, building on existing air quality, climate change and development agreements, and assessment, prioritization, and demonstration of promising SLCP mitigation measures.
  • Finance: The CCAC Financing Initiative is a cross-cutting action to bolster financial flows towards SLCP mitigation for reductions scale-up.
  • Assessments: There is a need for in-depth assessments of SLCPs in key regions to help shape regional cooperation as well as the action of national governments, and to encourage new action. This Initiative aims to fill that void.
  • Health: The overall goal of the initiative is to realize reductions in SLCPs in cities through joint, complementary action by the urban health and development sectors, and by reinforcing the important linkage between SLCP mitigation, air pollution mitigation, and health benefits. The initiative will provide a framework for collaboration among health, environment, and economic actors to achieve reductions across key sectors: transport, waste, housing, energy industry, and power generation.
