Conclusion

Does Environmental Policy Work? examines our ability to assess the impact of environmental policies on the environment in particular, and on social welfare in general. The distinguished authors explore the theory of assessment, concentrating primarily on a conceptual examination of the evaluation process. They extend existing tools and identify alternative indicators and methods of appraisal. The focus then shifts to the use of these tools in real-world policy situations by applying them to a series of case studies from Africa, North America, South America, Europe and Asia. Although the authors base their assessment predominantly on economic efficiency, they also pay due regard to other interdisciplinary approaches and decision-making criteria.
