Annual report: 2022-2023

Our partners' actions and Coalition-funded results from August 2022 to July 2023

the gaps

Through integrated climate and clean air action

Our 2022-2023 annual report highlights examples of the impact of the Climate and Clean Air Coalition's work across the globe to build a sustainable pathway to global climate and development goals.

A review of global progress in 2023 highlighted the disparity between commitments and action. As countries begin to update their Nationally Determined Contributions to the Paris Agreement for 2025, the Climate and Clean Air Coalition is demonstrating how available solutions can help quickly close these gaps. See how below.

Rick Duke
CCAC Co-Chair

Time and again, the Climate and Clean Air Coalition has proven itself to be indispensable for galvanizing action at the intersection of climate change and air pollution. The CCAC played a pivotal role in paving the way for the Kigali Amendment to the Montreal Protocol and then laid the groundwork for the Global Methane Pledge with its 2021 Global Methane Assessment. The Global Methane Pledge has since grown to over 150 countries, with the CCAC providing critical secretariat services. All the while, CCAC has artfully pulled together a broad network of governments and non-governmental stakeholders, produced world-class scientific analysis, and provided essential technical assistance and capacity building support to over 70 countries. And with the new Clean Air Flagship and forthcoming N2O assessment, there's much more to come. 

As we near the mid-point of this decisive decade, we urge further support for the vital mission of the CCAC, including for its goal of raising $100 million for the trust fund to achieve full implementation of the CCAC's 2030 strategy.

Peter Dery
CCAC Co-Chair

This year saw the CCAC 2030 Strategy move into a new phase of accelerated implementation, with many new projects launched and significant new partner engagement. By the end of 2023, the CCAC will have over 100 active projects around the world across 80 partner states. The fruits of the Coalition’s work are coming to bear in more countries formalising SLCP action within their nationally determined contributions, particularly in target areas such as methane. The CCAC was also prominent in supporting Africa Climate Week co-host Kenya in establishing itself as a leader in short-lived climate pollutant action in the continent.

As the CCAC ramps up its implementation of the 2030 Strategy at this moment of global stocktake in climate change mitigation, we call on all partners for their support. Significant gaps still exist between the scale of our challenge and current levels of ambition in nationally determined contributions and the funding directed toward mitigation action. Raising both political ambition and funding is now our joint priority to achieve the multiple climate, health, and development benefits that are within reach with sufficient action before 2030.


Over 160 partners worldwide

The CCAC partnership continued to grow in 2023, with additional countries and organisations committing to reduce short-lived climate pollutants. New local entities were awarded grants to implement CCAC projects through three open calls for proposals.

Bridging the ambition gap

CCAC partners continued to include short-lived climate pollutant measures in nationally determined contributions, policies, and regulations to generate increasingly ambitious climate and clean air action. Additional countries committed to SLCP action, joining the CCAC partnership and Global Methane Pledge.

Examples of national action


Has multiple new CCAC projects underway, including one to implement waste methane measures in its Nationally Determined Contribution.

Regional collaboration

The CCAC convened governments and regional bodies to address ambition gaps for cross-border challenges. Our regional ministerial meetings helped identify common priorities for SLCP action in the agriculture, fossil fuels, and waste sectors. And at regional climate weeks, our partners emphasized the urgent need for regional standards and strategies to raise ambition ahead of COP28 and UNEA-6.

Bridging the implementation gap

The CCAC is working to accelerate mitigation actions in the main SLCP sectors through a combination of capacity building, finance, and technology support. Over the past year, we lauched mitigation projects in 33 countries, working with governments and sector stakeholders to develop solutions that deliver on national development objectives and international commitments.

In 2023, CCAC Scientific Advisory Panel members and partner organizations provided new analysis on climate and health benefits to be achieved through SLCP reductions.

Closing the finance gap

While methane is responsible for nearly half of net warming to date, finance for methane emissions abatement accounts for less than 2% of global climate finance. At the same time, data shows a consistent trend of less than 1% of aid spending allocated to tackling air pollution. CCAC partners are working together to develop new sources of finance for SLCP action at scale.
