Protecting the world's most biodiverse sanctuary

Nestled in the dense forests of eastern Cambodia, the Keo Seima Wildlife Sanctuary (KSWS) is a haven for wildlife and a vital resource for the Indigenous Bunong people. The sanctuary spans over 292,690 hectares, with the REDD+ project area protecting 166,983 hectares of some of the most biodiverse forest in Southeast Asia.The KSWS REDD+ Project, launched in 2010, is a collaboration between the Royal Government of Cambodia's Ministry of Environment and the Wildlife Conservation Society (WCS). It represents Cambodia's largest carbon emission reduction program in the land use sector and is a key part of the country's commitment to the Paris Agreement. The sanctuary sits at a critical deforestation frontier. The neighboring Snoul Wildlife Sanctuary lost almost all of its 62,000 hectares of forest cover and was degazetted in 2018. The Keo Seima project has successfully held the line against this advancing wave of destruction, preventing approximately 25,000 hectares of predicted deforestation since 2010.
Avoids ~21 million tCO2e over 60 years across 166,983 forested hectares in Mondulkiri, with ongoing satellite monitoring to validate forest cover against credited volumes.
60-year crediting period supported by WCS management across 292,690 hectares, with active ranger patrols and government partnership mitigating regional land-use pressures.
Protects 85 threatened species with CCB Double Gold recognition, supporting indigenous Bunong communities through land patrols, education programmes, and livelihood diversification across 20 villages.
Strong deforestation baseline from historical logging and land conversion pressure in Mondulkiri, with carbon finance enabling dedicated ranger patrols and community livelihood programmes.
Verra VCS certified (VCS 1650) with CCB Double Gold under VM0015 methodology, demonstrating robust third-party verification and published monitoring reports.
