Access to justice in environmental matters has been a topic for increasing legal discourse and law-making in international, European Community (EC) and national arenas. The 1998 Aarhus Convention provides new norms of international law, inspired by the 1992 Rio Declaration. EC law on access to justice is being drafted and changes can be observed in the laws of the European Union (EU) members states. This book presents the access to justice in environmental matters in the European Union. It provides a thematic and comparative introduction of the topic, followed by thorough descriptions of EC law and the law of each EU member state. The chapters are written in English or French with a summary in the other language.
