CCAC NDC Watch: Latest on Non-CO₂ Pollutants in National Climate Plans
Since the last Climate and Clean Air Coalition NDC Watch, three countries have submitted new Nationally Determined Contributions (NDCs), the Maldives, Zambia and Cuba. The Paris Agreement does not require or specify how Short-Lived Climate Pollutants (SLCPs) should be integrated into NDCs, but there are multiple ways in which countries can include SLCPs in their NDC that can help to increase the climate and clean air benefits from its implementation. Targets, specific mitigation actions that reduce SLCPs, and outlining health and air quality benefits from NDC implementation can also demonstrate how a country can improve its own air quality and increase its climate change mitigation ambition. In addition, the strong overlap in sources of greenhouse gases and SLCPs mean that even where an NDC does not explicitly focus on SLCPs, the policies and measures identified to achieve an NDC in many cases will implicitly reduce SLCPs. This can lead to even larger climate and clean air benefits than a country may have intended without any additional effort.

Climate and Clean Air Conference 2025
Over the three-day conference, discussions focused on integrating ambitious strategies to reduce super pollutants into updated national climate plans (NDCs 3.0) and moving from momentum to action. As we head towards COP30 later this year, addressing super pollutants alongside deep decarbonization must take center-stage.
A series of new initiatives and action-underpinning reports were launched throughout the week, demonstrating the strong momentum behind super pollutant mitigation efforts. These include the release of a CCAC Technology and Assessment Panel (TEAP) report assessing the potential of black soldier fly technology to cut methane emissions from organic waste and a new policy brief on digital extension services for livestock to help reduce methane from the livestock sector.
Subnational governments, who are on the frontlines of the fight against climate change and air pollution, reaffirmed their commitment to tackling super pollutants, with the governments of Belém, Fortaleza, and Rio de Janeiro, joining the Lowering Organic Waste Methane (LOW-M) initiative, paired with the release of LOW-M’s new Data Guidance to support improved emissions tracking. This builds on the momentum of 62 countries signing the CCAC-supported COP29 Organic Waste Methane Declaration, which now represents over 50% of global waste methane emitters.
The CCAC, in partnership with Oxfam America, launched a landmark initiative to integrate gender equity into super pollutant mitigation strategies, recognizing the critical role of women in driving super pollutant solutions at the community level.
The Conference also advanced action across the CCAC’s six sectoral hubs — agriculture, heavy-duty vehicles and engines, waste, household energy, fossil fuels, and cooling. Cross-cutting sessions underscored the urgency of accelerating action on super pollutants ahead of COP30, while aligning climate and air quality policies for maximum benefits to public health, food security, and sustainable development.
Our sincere thanks to the CCAC Scientific Advisory Panel, Global Methane Pledge Champions, and all participants from national governments, NGOs, philanthropies, and international organizations. A special thank you to our hosts, the Government of Brazil, for hosting this year’s Conference and raising the bar on ambitious action on super pollutants.
20th session of the Group of Experts on Coal Mine Methane and Just Transition
Discussions at the 20th session of the Group of Experts on Coal Mine Methane and Just Transition (CMMJT) centered on the critical work of the Group and the imperative to move from reflection to future action.
Throughout the session, marking the 20th anniversary of the CMMJT, reflections on past achievements underscored the strong foundation built in methane emissions reduction and the evolving understanding of a just energy transition. Key milestones in mine safety, environmental standards, and addressing socio-economic impacts were highlighted.
