Who we are

The Climate and Clean Air Coalition is the only global effort that unites governments, civil society and private sector, committed to improving air quality and protecting the climate in next few decades by reducing short-lived climate pollutants across sectors.

Complementary to mitigating CO2 emissions, the Coalition acts as a catalyst to create, implement and share immediate solutions addressing near-term climate change to improve people’s lives rapidly, and to ensure sustainable development for future generations. 

Our Values

Our values

Action Orientated

With the combination of strong science, high level political will, and a range of cost-effective measures, we take fast action to seize the opportunity to achieve real and multiple benefits.


Partners voluntarily participate in the Coalition, dedicating their time and energy to reducing short-lived climate pollutants in their work, but also coming together to engage with others to multiply our efforts. 


Our broad partnership takes concrete action to reduce short-lived climate pollutants, collectively and individually. Leadership and implementation is collaborative; decisions are made by consensus.

Grounded in Science

The Coalition is a model for taking action based on solid science. Our Scientific Advisory Panel, with 13 eminent scientists, keeps abreast of the latest science on short-lived climate pollutants, and ensures we take the best course of action.


The Coalition's initial focus is on methane, black carbon, and HFCs. At the same time, partners recognize that action on short-lived climate pollutants must complement and supplement, not replace, global action to reduce carbon dioxide, in particular efforts under the UNFCCC.

The Coalition's objectives are to address short-lived climate pollutants by:

  • Raising awareness of short-lived climate pollutant impacts and mitigation strategies
  • Enhancing and developing new national and regional actions, including by identifying and overcoming barriers, enhancing capacity, and mobilizing support
  • Promoting best practices and showcasing successful efforts
  • Improving scientific understanding of short-lived climate pollutant impacts and mitigation strategies
  • Promoting best practices and showcasing successful efforts
  • Improving scientific understanding of short-lived climate pollutant impacts and mitigation strategies


The Coalition serves as a forum for assessing progress in addressing the challenge of short-lived climate pollutants and for mobilizing resources to accelerate action. It works to catalyse new actions as well as to highlight and bolster existing efforts on near-term climate change and related public health, food and energy security, and environmental issues.


Recognising that mitigating the impacts of short-lived climate pollutants is critical for addressing near-term climate change and that there are many cost-effective options available, the governments of Bangladesh, Canada, Ghana, Mexico, Sweden and the United States, along with the United Nations Environment Programme (UNEP), came together to initiate the first effort to treat these pollutants as a collective challenge. Together, they formed a unique initiative to support fast action and make a difference on several fronts at once: public health, food and energy security and climate.


CCAC and Partners

The Coalition brings together nations, institutions, organisations and companies to reduce short-lived climate pollutants with the aim of addressing near-term climate change and air pollution, and to improve people’s health, increase food security, enhance energy efficiency, and alleviate poverty.

Key Documents


[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.

One of the most valuable aspects of this Coalition is that it is bringing together developing countries to take the lead in reducing emissions, learning together and raising each other’s ambition. Tackling SLCPs has great benefits for our countries. The impact on health alone makes these actions compelling, but it’s clear that there are also great opportunities for sectoral development.

Tackling SLCPs presents companies with a significant opportunity to improve performance on both environmental and social fronts. What’s more, including SLCPs in a climate strategy provides operational and organization efficiency benefits, such as leaner supply chains, decreased raw material waste or loss, or a more efficient use of logistical resources.

Edward Cameron

Private Sector
While we must continue to aggressively reduce CO2 emissions, efforts to reduce short-lived climate pollutants like black carbon and methane can have an immediate effect on slowing warming. At the same time, such action can reap huge health, agriculture and other development benefits for the poorest and most vulnerable. Coalitions for action on SLCPs outside the UN climate convention, such as the Climate and Clean Air Coalition, help to demonstrate that success is possible and build confidence for advancing action in the negotiations.

When we work with cities on cost-effective measures to reduce short-lived climate pollutants and their numerous near-term benefits I am more confident than ever we can cut global warming in the near term and improve the quality of life and livelihoods of millions of people.
