The Cambodia Country Climate and Development Report (CCDR) provides analysis and recommendations on how Cambodia can achieve sustained development while responding to climate change and the low-carbon transition. Cambodia has high development aspirations, aiming to become an upper-middle-income country by 2030 and a high-income country by 2050. Achieving these goals will not be easy and will require a more inclusive, diversified, and productive economy. Climate change could amplify existing development challenges, with potentially sizable impacts on growth, trade, debt, and poverty reduction, as Cambodia faces one of the world's highest levels of exposure to floods and extreme heat. However, building climate resilience also offers an opportunity, not only to mitigate climate risks, but also to concurrently further development outcomes, as this report finds that adaptation measures in Cambodia have large development co-benefits. Moreover, Cambodia has made ambitious pledges in its Nationally Determined Contributions (NDC) and in its Long-term Strategy for Carbon Neutrality (LTS4CN). Delivering these commitments will require careful policy choices to mitigate transition risks and seize development opportunities. Finally, as a small, open economy highly dependent on trade and foreign direct investment (FDI), Cambodia will be highly affected by the accelerated decarbonization and changing consumption and production patterns in the rest of the world. With the right policy choices and a vibrant private sector, this could offer opportunities for export diversification, job creation, and growth.
