The transition away from fossil fuels in Europe is a crucial step toward addressing climate change. But also it is a process fraught with significant geopolitical and practical challenges. Traditional oil and gas suppliers to the European Union will face a significant decline in demand, and hence earnings, as Europe moves towards net zero. Many of these supplier countries are relatively poor, growing and in neighbourhoods much less stable than the EU. This seminar explores how the European Union will approach this challenge, how policy responses will be crafted (and why), and suggest some ideas for policy consideration. The Seminar will explore the multifaceted implications of this transitions impact on energy security, international relations, and domestic economic structures. Through an interdisciplinary lens, the discussion will shed light on Europe’s role in leading global energy transformation while navigating the intricate interplay between geopolitics. Because this presentation is from a policy practitioner, feedback and ideas are very welcome, and a participatory process to create ideas could be developed.
