The Asia-Pacific region is the major source of global growth in greenhouse gas emissions. Strong action is needed in Asian countries, particularly China and India, to reduce these global emissions. Driven by the desire to limit energy consumption, some Asian countries already have domestic policies to limit greenhouse gas emission. But much more ambitious policies are needed to turn emission trends around. This research report examines the implications of international efforts to mitigate the impacts of human activity on climate in the Asia-Pacific region.
