Providing an overview of UNEPs activities in 2009, this report looks at a broad range of activities carried out by the organization as it follows its mandate to provide environmental leadership and promote sustainable development.

The UNEP Year Book 2008 highlights the increasing complexity and interconnections of climate change, ecosystem integrity, human well-being, and economic development. It examines the emergence and influence of economic mechanisms and market driven approaches for addressing environmental degradation, and it describes recent research findings and policy decisions that affect our awareness of and response to changes in our global climate and environment.
