OECD Indicators

image of Environment at a Glance 2013

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.

Road traffic, vehicles and networks

Transport is a major component of economic activity in and of itself and as a factor input to most other economic activities. It has many effects on the environment: air pollution raises concern mainly in urban areas where road traffic and congestion are concentrated, though road transport also contributes to regional and global pollution problems such as acidification and climate change; vehicles present waste management issues; and transport infrastructure exerts pressures on the environment through use of space and physical transformation of the natural environment (e.g. fragmentation of natural habitats).
