ABSTRACT
EU environmental law applies to pollution not only within but also between Member States. This article discusses how the applicable rules take account of situations of cross-border pollution. In doing so, it looks at examples from different kinds of rules in the sense that they either address the source of pollution or regulate the overall resulting pollution. The article identifies cooperation requirements between the Member States in EU legislation and puts them in relation to the underlying principle of loyal cooperation. It shows how the legal requirements contribute to reducing cross-border pollution and looks at their limits. Further, it investigates the possibilities of enforcing the applicable EU environmental law in the event of cross-border pollution both in front of the Court of Justice and before national courts.
