The European Union (EU) aims to ensure a high level of environmental protection. This is a key message of primary EU law. This article explores the purpose and meaning of this explicit ambition. It deciphers its influence on case law and on judicial review of legislative and administrative discretion. It argues that the requirement goes beyond window dressing and that its added value lies both in supporting the legitimacy of bold decisions and in preventing a manifest dismissal of the requisites of environmental protection.
Although primarily focused on EU law and on its technicalities, the article may offer helpful insights to other transnational or federal systems. It may help to build a better understanding of some of the challenges facing any environmental law regime confronted with the sensitive issue of ‘ambition’.
