OECD Environmental Performance Reviews provide independent assessments of countries’ progress in achieving domestic and international environmental policy commitments and goals, together with policy-relevant recommendations.  They address the management of air, water, waste, biodiversity, and land; they examine the relationship between economic and social policy and the environment; and they describe the subject country’s international co-operation in such areas as climate change, marine pollution and development co-operation.  Each report includes a broad range of economic and environmental statistical data. On average, five or six countries are reviewed each year.
