This master thesis involves an analytic investigation of Danish lobby organisations’ influence through their lobby actions made on the institutions in the European Union. The core essence of the thesis re-volves around the question, whether the Danish lobby organizations actually are influential in terms of the policies made in the European Union. To be able to investigate the influence of Danish lobby or-ganisations’ influence in the EU institutions delimitations has been made and a specific case has been chosen. This thesis focuses the lobby actions made in regard to the Common Agricultural Policy, the largest policy in the EU budget wise, and specifically on the current reformation of the Common Agri-cultural Policy, which is currently in development, the CAP 2020 reform. In terms of Danish lobby actions made regarding the CAP 2020, the Danish lobby organisations included in this thesis consists of the Danish Agriculture and Food Council and the Danish Society for Nature Conservation. These lobby organisations have been chosen due to their relevance and direct involvement in the CAP 2020 reform. The Danish Agriculture and Food Council and the Danish Society for Nature Conservation both represent Danish- cooperatives, companies, employees, and the interests of the civil society, who have interests regarding the CAP 2020. Beside the Danish lobby organisations, the Danish Agriculture and Food Council and the Danish Society for Nature Conservation, two pan-European lobby organisations, where the Danish lobby organisations has their membership, are being included in this thesis. The two pan-European lobby organisations are Copa & Cogeca and the European Environmental Bureau. The included EU institutions is the European Commission, the European Parliament, and the Council of the European Union. The inclusion of these organisations and institutions creates a structural frame for the thesis, which enables the research to answer, whether the Danish lobby organisations have influence on the EU policy. This is an extremely relevant subject to investigate, since it can be used to answer ques-tions about the Danish legitimacy and influence on EU policy more generally. Most publications on lobbying at the European Union level are either made before the Lisbon Treaty in 2009, which gave the European Parliament legislative power, where the tables were turned regarding how lobbyism the EU works, or are made after 2009, but primarily been focusing on quantitative re-search. This thesis strives to contribute to the existing literature and broaden the field of research of lobbyism in the EU by both being current and with the use of a qualitative approach.
