No 256, OECD Environment Working Papers from OECD Publishing

Abstract: Studies that estimate the costs, benefits and environmental impacts of new policies provide essential decision support for policymakers. Although performing such assessments is standard practice for many ministries and regulatory agencies, their quality and supporting evidence often vary. Similarly, the evaluation of existing policies that are already in effect is essential for ensuring that they remain cost-effective and fit for purpose, and that opportunities for incremental improvements and learning are captured. This paper examines current practices across nine countries and the European Commission and provides insights on best practice for environmental policy assessment. The paper also reviews five case studies that showcase current practices. While the reviewed cases represent best practice or close to best practice, they also reveal opportunities for improvements. Several recommendations are provided based on the survey results and case studies.
