This report forms part of the OECD’s At a Glance series which provides snap-shots of key policy areas based on data and indicators. It does not attempt to assess progress in tackling key environmental challenges. Nevertheless, the picture that emerges is clear: while some progress has been made to mitigate environmental pressures in OECD countries, these pressures are continuing to increase. This requires more effective policies, as well as better indicators to establish targets and to measure progress in achieving them.
