War in Iran: Tracking European Responses

The Energy Centre at the Jacques Delors Institute analyses the responses adopted by the 27 European Union Member States to address the energy impacts of the war in Iran.

In this context, the Energy Centre has developed an interactive tracker compiling all national measures implemented across the EU. Regularly updated (every two to three weeks depending on the evolution of the conflict), this tool provides a comprehensive overview of the nature and timing of public policy responses. It aims to map and compare national approaches to the energy crisis, assess their short- and long-term effectiveness, and identify both best practices and emerging risks.
