Hierarchical methodological framework to improve Policy Environmental Assessment: Based on policy layer

Yinglie ZHOU, Cunkuan BAO,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1,   Pages 82-90 doi: 10.1007/s11783-010-0004-9

Abstract: This study explores the current implementation challenges of the Policy Environmental Assessment (PEA), including the implementation of a far richer, more diverse (at macro level), and better understanding of PEA and integration with decision making. The results contribute to the analysis of PEA through different hierarchies of assessment. Stemming from the theory and practice of policy, a concept of PEA hierarchies is proposed including the uppermost PEA, upper-lower PEA, and lowermost PEA. Afterward, the differences of the three hierarchies are interpreted, in terms of aims, principles, processes, and methods. The evaluation of the policy environmental impacts from different lens helps solve the complexities of policies and identify opportunities for improvement of PEA.
