With First Round of Full Meetings, CCAC Launches 7 Hubs to Mitigate SLCPs

by CCAC secretariat - 10 August, 2022
Over the last few months, the CCAC has brought together governments, inter-governmental and non-governmental organizations, and private sector leaders to focus on key SLCP emitting sectors and national planning in the first round of full Hub meetings

The world must make significant progress by 2030 if we are to slow the climate crisis, reduce air pollution, and address the poverty and inequality that threatens the most vulnerable. Humanity is pushing up against ecological limits, triggering multiple crises that threaten public health, food security, livelihoods, and the ecosystems that sustain us.

Over the last ten years, the Climate and Clean Air Coalition has improved the science behind SLCPs, shared what we have learned, and carried out activities in different sectors to test and prove the feasibility of available solutions. Through our 2030 Strategy, we are redoubling our efforts to deliver concrete, public health, food security, environmental, and economic benefits, while simultaneously slowing the rate of near-term temperature change.

As part of this strategy, the CCAC has created new Hubs which build off our first decade working with governments, inter-governmental and non-governmental organizations, and private sector leaders to advance action on SLCPs mitigation. These hubs, which address key topics, such as planning and the key SLCP source sectors, are open to all interested parties who wish to benefit from regular meetings providing opportunities for peer-to-peer exchange, technical discussions on best practices, and showcasing the latest science and analysis on SLCPs.

This May, June, and July, the CCAC held the first round of full Hub meetings:


In May, the Agriculture Hub heard from Costa Rica and Kenya, who presented on creating an enabling environment for enhanced climate ambition in the livestock sector. Speakers from the University of New England (Australia) and the Global Research Alliance on Greenhouse Gas in Agriculture presented on the latest science and research, and partners from FAO, Global Dairy Platform, Global Methane Hub, and WMO gave presentations on overcoming barriers to implementation in the livestock sector.

In June, the Cooling Hub held its first meeting, led by Canada and the Maldives. Speakers from academia, the Alliance for Responsible Atmospheric Policy, and Portan/Nuova Service presented on food cold chains, and Cambodia, Universiti Teknologi Malaysia, and UNEP gave presentations on lifecycle management. In addition, Canada led a discussion on potential opportunities for collaboration related to the Cooling Hub engagement strategy, the Kigali Workstream, and the life-cycle initiative. This included speakers from UNEP, UNDP, UNIDO, the World Bank, and Clean Cooling Collaborative/Climateworks.

Fossil Fuel

In June, a representative from the IEA presented to the Fossil Fuel Hub on curtailing methane emissions from fossil fuel operations. Participants heard from a panel of experts from countries, NGOs, industry, and the World Bank on overcoming barriers to governments seeking to regulate fossil methane and black carbon. In addition, participants contributed ideas related to the CCAC's Fossil Fuel Hub Engagement Strategy and to scaling up direct support to countries, reacting to geo-political developments, and identifying opportunities to advance work in preparing for COP27.

Heavy-duty Vehicles

In July, Cambodia and the US led the first Heavy-duty Vehicles and Engines first full Hub meeting. Cambodia also presented on their work to support the implementation of Euro 4/IV emissions standards, and Cote d'Ivoire gave a presentation on soot-free buses in Abidjan and the development of harmonized fuel and vehicle emission standards. A representative from the US EPA presented on a joint US-Polish project where green infrastructure is being used as a tool to mitigate local air pollution and SLCPs, and ICCT and UNEP presented on overcoming barriers to implementation.

Household Energy

In July, the Household Energy Hub had its first meeting, with Ghana and the US leading. Ghana gave a presentation on their experience with Article 6 and MRV, while Colombia’s presentation focused on their experience developing an implementation plan for their ambitious NDC target. Experts from the World Bank and the Clean Cooking Alliance presented on two digital tools meant to accelerate access to clean cooking solutions, and SNV and MECS presented on scaling up clean cookstoves.

National Planning

The National Planning hub first met in June. Presentations on the science and policy side came from CCAC Scientific Advisory Panel chair Drew Shindell (on methane emission and mitigation assessments), SEI (on consideration of methane mitigation in NDCs), Aether (MRV and SLCPs), and Clean Air Asia (city-scale action on air pollution and climate change.) The US EPA, the CCAC Secretariat, and the Global Methane Hub gave presentations on National Planning Engagement Strategy, the launches of both a methane roadmap development program and of calls for proposals, and updates and opportunities from the GMH, respectively. After a presentation from SEI, countries including Colombia, Côte d'Ivoire, Nigeria, Mexico, and South Africa presented on overcoming barriers to implementation of SLCP mitigation priorities.

In May, the Waste Hub met for the first time. Chile and the US EPA presented on monitoring, reporting and verification in the waste sector​, the EPA on a policymakers’ handbook and Chile on their development experience. C40 (accelerating action in waste management to deliver the Global Methane Pledge), IADB (exploring the cost of waste management—how can governments achieve cost recovery?), and the World Biogas Association (scaling up biogas) gave presentations on overcoming financial barriers to implementing waste projects​. IGSD gave an update on the hub leadership group, and the CCAC Secretariat discussed recent waste-based service requests from countries.)
