The third Energy Security Summit was held on 5 and 6 May 2015, again in Berlin. During the meeting, Iranian Oil Minister Bijan Namdar Zangeneh laid out his country's plans for the development of the energy sector after the end of sanctions. After the previously reached deal to resolve the Iranian nuclear crisis, the Minister demanded the rapid lifting of the economic sanctions. He dashed hopes that Tehran would build a gas pipeline to Europe to weaken the dominant role of Russia in the European gas market, citing transit problems and costs. At the same time, the Minister announced that his government would invest US$180 billion in the Iranian oil and gas industry by 2022. Other topics at the meeting included, among others, the proposed Energy Union in Europe, which both Maroš Šefčovič, Vice-President of the European Commission, and Rainer Baake, Parliamentary State Secretary in the Federal Ministry for Economic Affairs and Energy, called for, as well as the German energy transition. Bärbel Höhn, chairman of the German Bundestag's Environment Committee, referred to it as an important contribution by Germany to the creation of a global structure of a decentralized energy supply, which reduces dependencies and contributes to security and peace. Criticism came from Greenpeace head Kumi Naidoo, who stated that the high share of brown coal used for electricity generation was the “Achilles heel” of Germany's energy policy. Michael Fuchs, Deputy Chairman of the CDU/CSU parliamentary group, criticized the high burden placed on German citizens due to subsidies of 480 billion Euro earmarked for the energy transition.
