There is a constant struggle between the EU and its member states regarding which policy areas should fall under EU competence and therefore be regulated through EU legislation. Previous research has identified an interplay between frame and venue in EU policy development, and this thesis seeks to expand on the theory by applying it on an emerging EU policy area: energy security. The research process-traces certain events leading up to the implementation of an EU energy security policy and based on the theory from previous research does so by analyzing documents produced by the European Commission, the European Parliament and the Council of the European Union from 2005 to 2008. The result shows that when energy is framed as a “common issue” for the EU and its member states the legislation is also suggested to take place on an EU level which supports previous research for an interplay between frame and venue. The findings contribute to the field of EU policy research and seeks to deepen the understanding of the interplay between frame and venue.
