The Coalition helps partners and stakeholders create policies and practices that will deliver substantial reductions in short-lived climate pollutant emissions, starting now.

We support actions on the ground through our 11 Initiatives, Solution Centre and Action Programme to Address the 1.5°C Challenge.


The Coalition's partners and initiative participants work in cooperation with key short-lived climate pollutant emitters and other stakeholders from around the world to encourage, enable and catalyze action to reduce emissions.

To achieve real and ambitious reductions, the Coalition focuses on four key strategies:

  • Enable transformative action by providing knowledge, resources, and technical and institutional capacity to act and supporting the sharing of information, experience, and expertise
  • Mobilize support for action to put short-lived climate pollutants on the policy map through advocacy at all levels of government and in the private sector and civil society
  • Increase the availability of and access to financial resources to support the successful implementation of scalable, transformational action
  • Enhance scientific knowledge to help decision-makers scale up action and promote the multiple benefits of action on short-lived climate pollutants

The Climate and Clean Air Coalition is about remarkable leaders working together to bring solutions to scale. It's about collaboration with national governments, cities, companies, civil society groups, all working together to address today's most urgent problems: the air we breathe and the existential climate change we face.

The Coalition takes action through initiatives, which are partner-led and designed to provide transformative action in sectors or as cross-cutting efforts to reduce methane, black carbon and hydrofluorocarbons (HFCs).

These actions include:

  • Training and institutional strengthening
  • Support for developing laws, regulations, policies and plans
  • Technology demonstrations
  • Political outreach
  • Awareness raising campaigns
  • Co-funding and catalysed funding
  • Development of knowledge resources and tools
The coalition you have built among the private sector, finance, civil society, research and other institutions can help to build a new world of collaboration and high standards. The results of your actions can have an immediate impact: cleaner industries; cleaner engines and oil and gas production; cleaner recycling and waste processing; cleaner brick kilns and cookstoves; and cleaner urban air.

Control measures

The Coalition's activities follow sixteen control measures identified in a 2011 UN Environment and World Meteorological Organisation (WMO) assessment.

If implemented globally by 2030, these measures could reduce global methane emissions by as much as 40% and global black carbon emissions by as much as 80% relative to a reference scenario, preventing up to 0.5°C of warming. An additional 0.1°C could be avoided by replacing high-global warming potential hydrofluorocarbons with available low-global warming potential and not-in-kind alternatives within the same time frame.

These measures involve technologies and practices that already exist, targeting the primary sectors responsible for short-lived climate pollution emissions. Almost half of these measures could achieve net cost savings over their lifetimes, and many more could provide co-benefits for air quality, human health, ecosystems and food security.


Control measures: cooking and heating

To reduce black carbon emissions from traditional cooking and heating practices

  • Replace traditional biomass cookstoves with modern fuel cookstoves
  • Replace traditional cooking and heating with clean-burning biomass stoves
  • Replace wood stoves and burners with pellet stoves
  • Replace lump coal with coal briquettes for cooking and heating


Control measures: improved kilns

To reduce black carbon emissions from kilns and ovens

  • Replace traditional brick kilns with improved kilns
  • Replace traditional coke ovens with modern recovery ovens


Control measures: diesel vehicles

To reduce black carbon emissions from diesel vehicles

  • Use diesel particulate filters for road and off-road vehicles (EURO VI)
  • Eliminate high-emitting diesel vehicles


Control measures: flooded rice paddies

To reduce methane and black carbon emissions from agricultural practices

  • Ban open-field burning of agricultural waste
  • Apply intermittent aeration of continuously flooded rice paddies
  • Improve manure management and animal feed


Control measures: oil and gas industry

To reduce methane emissions from the production and transport of fossil fuels

  • Carry out pre-mine degasification and recovery and oxidation of methane from ventilation air from coal mines
  • Recover and use gas and fugitive emissions during oil and natural gas production
  • Reduce leakage from long-distance gas transmission pipelines


Control measures: waste management

To reduce methane from municipal waste

  • Separate and treat biodegradable municipal waste, collect landfill gas
  • Upgrade wastewater treatment with gas recovery and overflow control


Control measures: HFCs

To reduce hydrofluorocarbon emissions from refrigeration and cooling

  • Replace high-global warming potential hydrofluorocarbons with low-global warming potential alternatives
