New Regulatory Approaches in 'Greening' EU Policies

European environmental policy has been long characterised by traditional regulatory policy approaches. In recent years, however, the EU has begun experimenting with new forms of governance. In particular, the task of environmental policy integration (EPI) into sectoral policies has invited more flexible and participatory regulatory forms, emphasising at the same time the role of procedural guidance. This article traces the history of the EPI principle and links its effectiveness to specific governance characteristics. It argues that effective EPI is dependent on a combination of political leadership and public participation. While both terms appear in the EU's vocabulary on sustainable development and new governance, the EU is only slowly finding the appropriate forms to put them into practice. Coming from a tradition of governance by political élites, EU policy-makers are still relying too naïvely on the mobilisation capabilities of societal groups and on the power of 'good ideas'.
