The Catalogue, announced in the AccelerateEU – Energy Union communication and presented on 13 May 2026 at the Informal Energy Council, contains measures that EU countries can implement to reduce their oil and gas consumption in the short term, increase their clean energy production, and save energy.
This collection of best practice examples, based on the most efficient measures taken by EU countries since 2022, has a large-scale replication potential across the EU.
Besides providing rapid relief for citizens and industry, the catalogue presents policy action that can lead to a significant reduction of natural gas demand and use of oil and petroleum products.
A report published in 2025 by the Clean Energy Technology Observatory estimates that accelerating the implementation of existing EU energy rules would lead to a yearly reduction of
Catalogue structure
The Catalogue is structured around 3 themes, each covering a number of measures and examples from different EU countries.
These best practices were identified and selected through thematic studies, the IEA 2026 Energy Crisis Policy Response Tracker, engagement with EU countries, stakeholder consultations, and a range of existing initiatives implementing EU energy policy priorities at the local level (such as the EU Covenant of Mayors, Citizen Energy Advisory Hub and the Energy Poverty Advisory Hub).
- ensure a flexible and crisis resilient energy system
- timely, targeted and temporary support measures that are and aligned with long-term energy transition goals
- removing preferential treatment for fossil fuels
- enabling switch contracts/suppliers and prevent disconnection
Supporting immediate energy savings and fast roll-out of clean and energy efficient solutions, scaling European manufacturing capacity
- accelerating uptake of cost-effective and easy-to-install clean and efficient solutions
- promoting self-consumption and energy communities
- promoting efficient and affordable transport
- raising awareness
- providing investment certainty and stability for the clean energy transition
- scaling up and optimise public investments for efficiency and clean energy in buildings
- supporting efficiency and clean energy in industry and SMEs
Europe is facing difficult times due to the energy repercussions of the conflict in the Middle East. The Commission is here to support the Member States in addressing effectively and timely high energy prices. The measures we have outlined in this catalogue can be easily replicated across our countries and are meant to reduce the impact of the current situation on both households and businesses while accelerating the clean transition.
