CCAC Partner since

Cambodia joined the Climate and Clean Air Coalition (CCAC) in 2014 and has received funding and technical support from CCAC partners for activities in municipal solid waste, cooling, and national planning. The country has also established a National SLCP Unit in the Department of Air Quality and Noise Management which works to coordinate short-lived climate pollutant (SLCP) mitigation efforts across ministries.  

Cambodia's updated Nationally Determined Contributions (NDCs) increases the country’s emissions reduction commitment, setting new and more ambitious targets for multiple sectors. There are detailed mitigation actions for energy, industry, waste, and agriculture, including increasing the amount of waste disposed at landfills, applying landfill gas extraction technology, and building biodigester plants on farms to produce bioenergy.  

The NDC places a strong emphasis on Cambodia’s 2014-2023 Climate Change Strategic Plan (CCCSP) to implement mitigation measures. This comprehensive and cross-sectoral plan addresses national barriers to implementation, such as the country’s current dependence on charcoal for household energy and its vulnerability to air pollution. The plan also sets out a national roadmap with broad strategic objectives for enhancing climate resilience, building capacity, and enhancing collaboration and partnership across government ministries. The development of the CCCSP was also foundational in embedding climate change into Cambodia’s development agenda, as formalized in the 2019-2023 National Strategic Development Plan.   

SLCP emissions from the major emitting sectors are addressed in the five-year sectoral Climate Change Strategic Plan established in 2014. The Climate Change Priorities Action Plan for Agriculture, Forestry, and Fisheries Sector set a priority to enhance livestock manure management and scale up climate-smart agriculture through pilot projects. 

The Climate Change Strategic Plan for Manufacturing Industry and Energy includes a goal to phase down ozone-depleting substances. This plan is targeted at shifting industry and energy provision towards renewable and sustainable sources and promoting energy access and security across the country.  

The Strategic Plan For Climate Change Adaptation And Greenhouse Gas Mitigation In the Transport Sector provides a strategic framework to enhance transportation infrastructure for climate change adaptation, and push for emission standards and public transportation as mitigation measures. This plan includes action to take heavy-duty vehicles off the road and build capacity for more stringent vehicle inspection and maintenance to reduce emissions. 

Public health is a major concern when tackling climate change impacts in Cambodia due to its vulnerability to severe flooding and the impacts of air pollution. The 2019-2023 National Climate Change Action Plan for Public Health is Cambodia’s response to mitigating these risks. This Plan includes mitigation measures and indicators to measure the health impacts of climate change. Read below for more information on sector-specific policies in Cambodia.

Other activities

Air quality 

  • The Clean Air Plan of Cambodia adopted in 2021 identifies activities to reduce greenhouse gas emissions and improve air quality. The plan outlines the country’s air quality status, main sources, legal documents, and management programs for major emitting sectors, and targeted mitigation measures.  
  • Cambodia is conducting black carbon surveys for some provinces, aiming to obtain baseline data of black carbon emissions in the country from 2021.  
  • The Sub-Decree on the Control of Air Pollution and Noise Disturbance, adopted in 2000, specifies thresholds such as the maximum allowable pollution concentration in ambient air and the air quality standard for different periods of time.  
  • The government circular No.01 on Measures to Prevent and Reduce Ambient Air Pollution, adopted in 2020, outlines 7 measures for relevant ministries, institutions, and sub-national administration to prevent and reduce ambient air pollution. The measures target construction sites, high sulfur content fuels, vehicles, production sites, open waste burning, urban environments, and enhancing air pollution monitoring and forecasting systems.    


  • Aimed at controlling import, export, and movement of Ozone Depleting Substances (ODS) within the country, Cambodia adopted Sub-Decree no. 47 on ODS Management in 2005. The decree was amended in September 2021 to empower the Ministry of Environment to control the movement of HFCs in Cambodia. 
  • In 2019, Cambodia ratified the Kigali Amendment to the Montreal Protocol, committing to phase down HFCs. 
  • The National Cooling Action Plan, developed with the UN Environment Programme and the Cool Coalition identifies actions to reduce emissions from the refrigeration and air conditioning sector. This action plan was included in Cambodia's updated NDCs. 


  • From 2012-2015, the Cambodian Ministry of Mines and Energy worked with the European Union, SNV Netherlands Development Organization, and SWITCH-Asia on a waste-to-energy project which aimed to produce electrical energy from rice husks. The partners provided technical support and assisted with developing a national standard of waste-to-energy technology for rice millers. 
  • The municipality of Battambang joined the CCAC Municipal Solid Waste city network in 2014. A work plan was created to address SLCPs in the waste sector promoting waste separation, reducing, recycling, and reusing.  
  • Cambodia adopted Sub-Decree No.113 on Municipal Solid Waste Management in 2015, aiming to improve effective Municipal Solid Waste Management, transparency, and accountability to ensure aesthetics, protect public health and the environment. 
  • Further improvement of municipal solid waste management is facilitated by sector-specific guidelines released in 2016 and Prakas No. 249 adopted in 2019.
