How to Navigate the Transposition of RED III

How to Navigate the Transposition of RED III in EU Member States?

When trying to understand how RED III is being transposed across the EU, you can easily find a multiple of publications often with overlapping or even contradictory information.

To analyse this topic effectively, I recommend the following key resources:

1️⃣ Announcements of the European Commission

  • On 24 July 2025, the European Commission opened infringement procedures by sending letters of formal notice to 26 Member States for failing to communicate the full transposition of RED III into national law.
  • Member States were required to notify the transposition of the RED III by 21 May 2025.
  • Only Denmark has notified full transposition by the legal deadline.

👉 This means that as of July 2025, only Denmark had fully transposed RED III.

2️⃣ Information on National Transposition in EUR-Lex

  • While EUR-Lex does not confirm full transposition, it provides a list of national measures adopted for implementing RED III, presented separately for each EU country.

3️⃣ Overviews by Associations, Research Centres, and Institutes

  • Such overviews can be very insightful but usually do not provide full information on RED III transposition. They often cover only some Member States or some parts of the RED III transposition such as hydrogen and others.
