Emissions associated with Short Lived Climate Pollutants (SLCPs) are harming millions of people around the world through their direct and indirect impacts on human health, agriculture, ecosystems, and global and regional climate.

SLCP sources vary from country to country, ranging from black carbon and associated emissions from traditional brick production, inefficient cookstoves, and in the exhaust from diesel engines, to the leakage of methane from oil and natural gas production, and methane emissions from the decomposition of waste in landfills and agricultural practices. Compelling scientific evidence indicates that fast action to control SLCPs will have immediate and significant and multiple climate and air quality benefits for communities around the World. For example, global action on black carbon and methane can help slow down expected warming in 2050 by up to 0.5 degree Celsius and avoid about 2.4 million annual premature deaths and 52 million tonnes of annual crop loss by 2030.

Action at the national scale is important, as decision making is often made at that scale. Rapid reductions in emissions from SLCP sources can be achieved through the implementation of cost-effective measures using national policies, programmes and regulatory frameworks, such as those used to address air quality, climate change and sustainable development. The need for urgent action to address SLCPs is now widely recognised, but support for national governments is needed to identify and promote the key mitigation measures that can bring rapid climate, health and environmental benefits.

The SNAP Initiative (Supporting National Action and Planning on SLCPs) of the Climate and Clean Air Coalition (CCAC) is a collaborative programme aimed at supporting the efforts of CCAC partner countries to scale up action on SLCPs in a coordinated and prioritized way. This includes helping them identify and implement the most cost-effective pathways to large-scale implementation of SLCP measures, i.e. those that reduce near-term warming and improve air quality, human health and crop yields1.

The SNAP initiative aims to address various challenges countries are facing to up-scale action. These include:

  • Lack of awareness of the SLCP issue amongst the key government departments and stakeholders in the country;
  • Lack of knowledge of SLCP emission sources, the magnitude of relevant emissions, and the potential for mitigation that hinders the ability to take informed decisions;
  • A lack of institutional capacity to coordinate the implementation of SLCP measures;
  • Scattered, uncoordinated action implementing measures that achieve the near-term climate, health and ecosystem benefits and no or limited planning that would embed SLCP policies within national strategies, plans and programmes;
  • A lack of consideration of the role that regional and other international processes and agreements could play in the mitigation of SLCPs.


Top facts

Total deaths caused by air pollution in the 14 SNAP countries = 426,976 premature deaths
Total crop yield loss 2,110,000 tonnes (or 2.1 million tonnes) from 14 countries caused by ozone pollution
16 measures targeting Black Carbon and Methane implemented fully in all countries of the globe can avoid 0.5 degrees warming by 2050



The goal of the SNAP Initiative is to develop capacity within SLCP partner countries for effective national planning as a foundation for rapid and large-scale implementation of SLCP mitigation. It has three key objectives:

  • Supporting the development of national SLCP planning processes - facilitating action in countries by embedding SLCPs in on-going activities and policies, and building capacity to coordinate issues related to SLCPs at the national scale to identify national priorities; and providing regionally coordinated support for institutional strengthening in participating countries;
  • Enhancing tools and approaches to support key steps of the national planning process – the development of emission scenarios, estimation of benefits of emission reductions to help in prioritising different measures for SLCP reduction;
  • Fostering linkages and collaboration between national SLCP planning with global and regional processes, initiatives and approaches.

Description of activities

Activity | SNAP
Peru | Ongoing
Since the Peruvian government joined the Climate & Clean Air Coalition in 2016, the Ministry of Environment has enhanced capacities towards the mitigation of Short-Lived Climate Pollutant (SLCP)...
Lima, Peru


Over the last year, the initiative expanded its training activities to help countries develop national SLCP mitigation strategies and use LEAP-IBC (500 person days of training in total). An awareness raising workshop for the Middle East and North African region brought together about 50 government officials from 16 countries across the MENA region. In response to the Coalition’s Marrakech Communique, Chile and Peru presented their first black carbon inventories at the April 2017 Working Group in Santiago. 

The initiative is developing a proposal to support countries develop black carbon inventories and integrate SLCPs into their NDCs, and strengthen links to the Long Range Transboundary Air Pollution (LRTAP). 

5-year milestones:


  • 23 countries receive support from the SNAP Initiative.
  • 13 countries have dedicated staff to coordinate SLCP mitigation (Institutional Strengthening support) – with 9 additional countries to come. 
  • 9 countries are working on national SLCP plans and another 4 will start shortly. 
  • A toolkit – that includes the Long-range Energy Alternatives Planning - Integrated Benefits Calculator (LEAP-IBC) – and a guidance note were finalized and are used by countries to guide SLCP mitigation strategies.
  • Creation of a community of practice at regional and global level through peer-to-peer exchanges on national planning and SLCPs.

What is the SNAP LEAP IBC toolkit?

The Long-range Energy Alternatives Planning System (LEAP) Integrated Benefits Calculator (IBC) toolkit is a piece of software that enables developing country practitioners to make a start on compiling SLCP emission inventories, generating mitigation scenarios and estimating benefits of action. It encourages countries to use nationally available data and uses internationally recognised  statistics where data gaps exists so countries can start to prioritize their action.

For more information, a webinar is available following this link.
