OECD Environmental Outlook to 2030

image of OECD Environmental Outlook to 2030

The OECD Environmental Outlook to 2030 provides analyses of economic and environmental trends to 2030, and simulations of policy actions to address the key challenges. Without new policies, we risk irreversibly damaging the environment and the natural resource base needed to support economic growth and well-being. The costs of policy inaction are high.

But the Outlook shows that tackling the key environmental problems we face today -- including climate change, biodiversity loss, water scarcity and the health impacts of pollution -- is both achievable and affordable. It highlights a mix of policies that can address these challenges in a cost-effective way. The focus of this Outlook is expanded from the 2001 edition to reflect developments in both OECD countries and Brazil, Russia, India, Indonesia, China, South Africa (BRIICS), and how they might better co-operate on global and local environmental problem-solving.

Climate Change

This chapter examines the projected emissions of greenhouse gases to 2030, by country and sector, and the expected impacts in terms of temperature change and other effects. Without new policies, it is projected that greenhouse gas emissions will increase by about 37% in 2030 compared to 2005 levels, with a wide range of impacts on natural and human systems. The chapter examines the key drivers of increases in greenhouse gas emissions, and explores a range of policy scenarios for reducing these emissions. It finds that early action by all emitters, covering all sectors and all greenhouse gases, can achieve an ambitious emission reduction target at low cost. It highlights the need to share the burden of the cost of mitigation action amongst countries.
