The participation of stakeholders in policy formation has increased, based on the recognition that policy-makers today face increasingly complex and non-linear problems, requiring flexible modes of governance. In this chapter, I analyse the role of formalised stakeholder consultations in EU energy policy and their potential of integrating climate change issues. More specifically, I empirically investigate how stakeholder consultation processes influenced the formation of the EU Energy Communication of 2007. The analysis shows that there was limited diversity of participation in consultations, as actors from civil society or NGOs were not included. Moreover, the role of scientific knowledge in the consultations was minimal. Actors at the regional and sub-national level are generally ignored in such formalised consultation processes. Recommendations for EU policymakers and organisers of consultations are provided.
