ABSTRACT
This chapter considers the legal development and implementation of transboundary environmental impact assessment (TEIA) in European Union (EU) or European law, from the introduction of brief provisions in the original EIA Directive to their expansion in the amended EIA Directive to implement the Espoo Convention. More recently, directives for public participation and strategic environmental assessment (SEA) have also contained provisions relating to TEIA, partly to implement aspects of the Aarhus Convention. In addition to the substantive law, the chapter examines the role of the European Commission and European Court of Justice (ECJ) in reporting on, implementing and enforcing these directives where relevant to TEIA.
