This regional study examines how strategies for adapting to climate change up to 2050 can be combined with measures to reduce greenhouse gas emissions in East Asia. Besides discussing climate model results for costs of adaptation in infrastructure, coastal protection, and agriculture, the study estimates costs for sector-specific mitigation options and the total abatement potential for 2020 and 2030. Long-term strategies for addressing the impacts of climate change in East Asia are explored with a focus on the linkages between adaptation and mitigation taking account uncertainty about key climate variables. Finally, it discusses opportunities for enhancing the effectiveness of some critical climate change policies such as regional carbon markets.
