Abstract
European Union (EU) environmental policy can only work in practice when it is implemented by and within the member states. Yet, despite its importance, we still lack a solid and cumulative understanding of the practical implementation of EU environmental policies, mainly because of the dominance of case-specific empirical insights and the dichotomous conceptualization of compliant implementation. This paper proposes a conceptual framework for analysing implementation performance, which is built around three dimensions: substance, scope and effort. The framework's relevance and analytical quality are substantiated by a systematic review of empirical studies on practical implementation of 18 EU environmental directives. We find evidence of three types of knowledge deficits: there is neglect of the ‘scope’ and ‘effort’ dimensions of implementation; disproportionate attention to the Water Framework Directive, and the Northern and Western European member states. The proposed conceptual framework aims to inform future research on EU environmental implementation. © 2017 The Authors.
