As countries update their Nationally Determined Contributions (NDCs) and enhance ambition to achieve the Paris Agreement temperature goals, the Climate and Clean Air Coalition is encouraging and supporting them to include short-lived climate pollutant (SLCP) and air pollution actions into their climate commitments.
There are various advantages to including SLCP and air pollution specific measures into revised NDCs:
- NDC ambition is enhanced by including SLCP actions due to their cross-cutting benefits impacting climate, air pollution, public health and sustainable development
- Actions that mitigate SLCPs and air pollution are easily integrated into existing national plans and strategies
- Immediate benefits are realized at the national and subnational level, while simultaneously contributing to global climate targets
- Integrated SLCP and air pollution actions benefit multiple sectors which strengthens co-governance by increasing cooperation between ministries and reducing duplication of efforts
As of October 2021, the CCAC has supported 14 countries to enhance ambition in their NDCs by including actions to reduce short-lived climate pollutants.
Eight are complete: Bangladesh, Chile, Colombia, Costa Rica, Dominican Republic, Mexico, Mongolia, Nigeria
Work is ongoing in Benin, Cote d’Ivoire, Eswatini, Liberia, Mali, Zimbabwe.
NDC case studies
The CCAC offers national policy and planning support that integrates climate and air quality objectives to maximize the benefits of action. SLCP mitigation measures are cross-cutting and applicable in multiple sectors, making them an effective way for countries to increase the ambition of their revised NDCs.
The CCAC has provided support to several countries that are raising the ambition in their NDCs. This is done through national policy and planning support that helps builds the capacity of countries to address SLCP measures in the NDC revision process. Learn more about our Strategic SLCP Planning activities:
Mongolia identified the potential air pollution mitigation benefits that can be achieved with enhanced commitments in their revised NDCs with help from the CCAC.
The Dominican Republic has been working with the CCAC to create emissions inventories and potential future mitigation scenarios. This information will then be used to generate a recommendation report for the country's NDC revision process.
Colombia’s revised NDCs include a 40% reduction target for black carbon by 2030 which was informed by their National SLCP Strategy developed with the CCAC.
Benin is receiving continued support from the CCAC to include measures from its National Report on Short-Lived Climate Pollutants into its revised NDCs.
The Maldives has worked with the CCAC to integrate existing sectoral plans with NDC targets to create a comprehensive National Action Plan on Air Pollutants.
Nigeria and the CCAC developed a National Action Plan to Reduce SLCPs within the country which has enhanced coordination between sectors and mainstreamed SLCP considerations into relevant cross-cutting plans and mechanisms.
Examples of sectoral commitments
SLCP mitigation measures are applicable across a variety of sectors. Find out how CCAC partner countries have enhanced their NDC ambitions by implementing actions that both directly and indirectly reduce SLCP emissions.
- Bangladesh: Enhancing railway transport networks; enhancing fuel quality; introducing Euro III and IV vehicle standards.
- Mongolia: Introducing Euro-5 standard fuels; switching coal export transportation from vehicles to rail transport; switching the heating of passenger trains to electric heating.
- Maldives: Establishing vehicle and vessel emissions standards; establishing an efficient transport management system; promoting hybrid vehicles.
Oil & Gas
- United States of America: Updating standards and investing in plugging leaks from wells and mines across the natural gas distribution infrastructure.
- Bangladesh: Establishing bio-gas plants to reduce landfill emissions.
- Cambodia: Establishing new sanitary landfills with landfill gas extraction; composting biodegradable organics from MSW, supplemented with separating organic waste at the source.
HFCs & Efficient Cooling
- United States of America: Implementing the American Innovation and Manufacturing (AIM) Act to phase down the use of hydrofluorocarbons.
- Bosnia – Herzegovina: Increasing the efficiency of heating and cooling systems; implementing energy efficiency labeling; banning imports of used heating and cooling equipment.
