This pathbreaking book contributes to the discourse of evidence-based policy-making. It does so by combining the two issues of policy evaluation and sustainable development linking both to the policy-cycle. It covers contributions: - examining the perception of sustainability problems, which analyze the relationship between sustainability and assessment;
- highlighting the role of evaluation and impact assessment studies during policy formulation;
- looking at policy implementation by examining sustainability and impact assessment systems in different application areas;
- addressing policy reformulation by considering monitoring and quality improvement schemes;
- assessing the quality of sustainability evaluation studies.

Providing theoretic insights, reflections and case studies, this novel study will prove essential to postgraduate students, practitioners, policy makers and researchers in the area of sustainable development, policy making and evaluation.
