How the EU handles uncertain risks: understanding the role of precautionary principle

Abstract:

The European Union (EU) has adopted the precautionary principle (PP) as a legal principle for dealing with uncertain risks; that is situations in which the relationship between activities and their potential hazard cannot be established. While the PP's application has been defined by the European Commission and EU case law, political considerations ultimately determine whether and how it is invoked. This article reviews the literature on the PP's application in EU policy making by addressing three research questions: When do EU policy makers invoke the PP? How are EU precautionary policies made? Is the making of EU precautionary policies different from the making of regulatory policies addressing certain risks? While the conceptual literature provides some insights regarding all three questions, the empirical literature is particularly instructive regarding the first two questions. Future studies have the task of merging the two literatures in order to obtain a comprehensive understanding of EU precautionary policy making.
