This thesis is about EU energy security in relation to Russia and its proposed Nord Stream 2 project. In this thesis the Copenhagen School theory on securitisation is applied with the help of a combination of content analysis and discourse analysis as methods, which will together with the theory become the framework of this study. While the focal point will fall on EU’s Parliament and how the project Nord Stream 2 is securitised within this EU structure, where the project itself will serve as an exhibitory example of the energy security relationship between EU and Russia. The main findings that are made in this thesis are that the securitising actors in the debate are the countries not the political parties and that Russia, not Nord Stream 2 is the true object of securitisation. In addition to that it was established that there is little unity amongst the EU member states, which is supported by the finding in previous academic studies that have been conducted within the field.
