OECD analysis shows that large reductions in greenhouse gas emissions are achievable at relatively low costs, if the right policies are put in place. This includes strong use of market-based instruments world wide to develop a global price for emissions, accompanied by better integration of climate change objectives in relevant policy areas such as energy, transport, building, agriculture or forestry, and other measures to speed technological innovation and diffusion.

Since the early 1990s, most industrialised nations and many developing countries have implemented climate change-related policies. The OECD has contributed to the debate through its analytical work on the design and implementation of effective climate change policies, as well as its peer reviews of policy performance in individual countries. This policy brief summarises the main messages of OECD work to date, and provides suggestions for how governments can achieve their climate change commitments in the future.
