Environment at a Glance 2013
OECD Indicators
This book includes key environmental indicators endorsed by OECD Environment Ministers and major environmental indicators from the OECD Core Set. These indicators reflect environmental progress made since the early 1990s and thus contribute to measuring environmental performance. Organised by issues such as climate change, air pollution, biodiversity, waste or water resources, they provide essential information for all those interested in the environment and in sustainable development.
