Kritische Rohstoffe in der EU - Herausforderungen und Handlungsfelder - Simon Jerome Dietewich

The war in Ukraine reveals the EU's painful dependence on Russian oil and gas. This fact is sufficiently present in the media, but another threat is rising on a different raw material front. The EU is highly dependent on high-tech minerals, so called "critical raw materials". These are needed to produce computer chips, rechargeable batteries or alloys that are indispensable for our everyday lives, the technological mastering of the climate crisis and defense technologies. Commodity exporting countries have already recognized their value and are using this for political reasons. This article provides an overview of the critical raw materials in the EU, the challenges of procurement and the action taken by the EU since 2008.

The Evolution of the EU’s Perception towards Ukraine - Kateryna Khalabuzar

Getting an EU perspective and a candidate status took Ukraine through a long, complex, and controversial integration path. Since the declaration of its independence in 1991, Ukraine has undergone tremendous changes in terms of political and nation-building processes that could not go unnoticed by the EU. From being ‘terra malecognita’ on the periphery of Europe, Ukraine has become a symbol of defending European values. Thus, to get a better insight of how the EU’s perception of Ukraine has developed over time, it is also crucial to shed light on key turning moments and political developments in Ukraine, which brought fundamental changes to the EU’s understanding of Ukraine.

The European digitalisation ambition: Halfway there?

The digital transformation is one of the most important developments of the recent past. In order to keep pace with this and to actively shape and steer it, the EU has made digital legislation one of the most important issues. This issue takes a closer look at the legislation in the area of digitalisation and deals with the major projects and recent developments. In particular, the Digital Markets Act and the Digital Service Act are the European Union’s flagship legislation packages, which is why they are examined in detail. It also looks at developments in digital infrastructure, digital healthcare and the space programme.

Das politische Denken der Europäischen Union

Supranational und zukunftsoffen. by Ludger Kühnhardt

The European Union should be based on the idea of European sovereignty, as French President Emmanuel Macron designed the future of the EU in 2017. The concept of European sovereignty connects questions of political thought with the internal order and the global political strategy of the EU. From a historical perspective, modern political thought has evolved around the concept of the state. However, ancient roots of political thought indicate that fundamental questions of political order were already reflected in a context prior to the evolution of the modern state. Important concepts of political philosophy emerged in ancient Greek and Roman history that continue to have an impact today. Against this background, this textbook Ludger Kühnhardt discusses in this innovative text book whether and how political thinking can also generate its own concepts and reflections in a supranational context, and especially in the European Union..
