"Uncertain Risks Regulated" compares various models of risk regulation in order to understand how these systems shape the relationship between law and science, and how they attempt to overcome public distrust in science-based decision-making. The book contributes to the ongoing debate relating to uncertainty and risks - and the difficulties faced by the European Union in particular - in regulating these issues, taking account of both national and international constraints. The term 'uncertain risk' is comparable with notions of hazard and indeterminate risk, as deployed within the social sciences; but it also aims to capture the modern regulatory reality that a non-quantifiable hazard must still be addressed by society, law and its regulators. Decisions must be taken in the face of uncertainty. And, whilst it is not possible to provide clear cut models of risk regulation, in focusing on regulatory practices at a national, EU and international level, the contributors to this volume aim to use fact finding as a core instrument of learning for risk regulation.
