The Netherlands’ Environmental Assessment (EA) system has continuously been discussed with calls for streamlining and simplifying. This paper aims to provide an overview and to examine these discussions, including their more fundamental background. To this end, we discuss the origins of the Dutch EA-system, its practice, the critique, the regulator’s reaction by changing institutional arrangements, and the consequences. We conclude that politically, EA is blamed for cumbersome planning and decision-making, while professionals are more nuanced. We see a process of persistent cumbersome planning and decision-making about plans and projects in a country in which environment and nature are under pressure. This situation is resulting in impromptu ‘escape routes’ and evermore detailed EA-studies that are costly, time-consuming, lack quality, are contested, and often fail before court. This process is observed for a long time. Although most studies stressed that streamlining and simplifying will not help in accelerating the planning process, nevertheless regulatory changes aimed at this because of political pressure. Overall, as a consequence of the simplification of regulations and the reduction of safeguards, the advanced and comprehensive nature of the original Dutch EIA-system has been called into question. EA as a messenger intrinsically will always be subject to critique.
