1. Subject matter of the proposal

This proposal concerns the Council’s approval of the Commission decision establishing the position to be taken by the Member States, as regards matters falling under the Euratom Treaty, in the Energy Charter Conference in connection with the envisaged adoption of a proposed amendment to Article 49 (Depositary) of the Energy Charter Treaty (‘ECT’) and the approval of (i) a new understanding with respect to Article 49 ECT on the roles of the Energy Charter Secretariat (‘Secretariat’), and (ii) a decision of the Energy Charter Conference on the designation of the Secretariat as depositary under Article 49 ECT in the interim period as of 2 February 2025. The adoption of the amendment to the ECT and the additional approvals are to be passed simultaneously by the Energy Charter Conference.

2. Context of the proposal

2.1. The Energy Charter Treaty

The ECT is a multilateral trade and investment agreement applicable to the energy sector that was signed in 1994 and entered into force in 1998. The ECT contains provisions on investment protection, trade and transit in energy materials and products, and dispute settlement mechanisms. The ECT also sets up a framework for international cooperation in the energy field between its Contracting Parties. Euratom is party to the ECT together with the European Union1 and most EU Member States, as well as Japan, the United Kingdom, Switzerland, Turkey and most countries from the Western Balkans and the former USSR, with the exception of Russia2 and Belarus3. On 30 May 2024, the Council adopted a Decision4 concerning the withdrawal of Euratom from the ECT and mandated at the same time the Member States to not oppose the adoption by the upcoming Energy Charter Conference on 3 December 2024 of the modernised provisions of the ECT. Euratom notified its withdrawal to the depositary of the ECT, which will take effect on 28 June 2025.

2.2. The Energy Charter Conference

The Energy Charter Conference is the governing and decision-making body, established by the ECT. All states or Regional Economic Integration Organisations (such as the EU and Euratom) who have signed or acceded to the ECT are members of the Conference, which meets on a regular basis to discuss issues affecting energy cooperation among the ECT signatories, to review the implementation of the provisions of the ECT and the Protocol on Energy Efficiency and Related Environmental Aspects, and to consider possible new instruments and joint activities within the Energy Charter framework. In particular, the Energy Charter Conference adopts texts of amendments to the ECT and approves modifications of, and technical changes to, the Annexes to the ECT. When voting on proposed amendments to the text of the ECT, the Energy Charter Conference passes a decision to adopt the amendments by unanimity vote of the Contracting Parties present and voting, subject to a quorum of at least half of all Contracting Parties. Euratom and the EU have a number of votes equal to the number of their Member States that are Contracting Parties to the ECT, provided that Euratom and the EU shall not exercise their right to vote if their Member States exercise theirs, and vice versa.

2.3. The envisaged act of the Energy Charter Conference

Article 49 ECT sets out that the Government of the Portuguese Republic shall be the depositary of the ECT. On 1 February 2024, the Portuguese Republic notified its intention to withdraw from the ECT and cease to be the depositary of the ECT, effective on 2 February 2025. Against this background, between July and August 2024 the Contracting Parties discussed the proposals to designate the Secretariat as a new depositary under Article 49 ECT following the withdrawal of the Portuguese Republic. In particular, they agreed to put forward to the Energy Charter Conference the following proposals and to vote on them as part of the already prepared modernisation package of the ECT:

(a) an amendment to Article 49 ECT designating the Energy Charter Secretariat as depositary of the ECT (CC 760 REV2);

(b) a new understanding with respect to Article 49 ECT on the roles of the Energy Charter Secretariat, as secretariat and as depositary (CC 762 REV2).

The agreed proposals are to be voted on 3 December 2024, during the 35th meeting of the Energy Charter Conference. The decisions related to the modernisation of the ECT will be subject to unanimity vote and a quorum of at least half of all Contracting Parties present. If the vote is successful, the decisions will be considered adopted by the Energy Charter Conference. This adoption will trigger subsequent processes for the ratification, provisional application, and eventual entry into force of the various elements of the reform package, including the amended Article 49 ECT and a new understanding under that Article on the roles of the Secretariat.

The provisional application of the amendments to the ECT, including the new amendment to Article 49 ECT on depositary, and the other elements of the modernisation will be governed by the decision regarding the entry into force and provisional application of amendments to the text of the ECT and changes/modifications to its Annexes and Understandings. However, in the discussions it has become clear that not all Contracting Parties will be able to provisionally apply the amendment to Article 49 ECT and the new understanding on the depositary. In order to ensure institutional continuity for the function of depositary as of 2 February 2025, the Contracting Parties agreed to propose to the Energy Charter Conference

(c) an additional, self-standing draft Decision which designates the Secretariat as depositary under Article 49 ECT in the interim period, starting on 2 February 2025, until the entry into force of the modernised ECT (CC 814).

The latter Decision will not as such be part of the package concerning the modernisation of the ECT and will be adopted at the Conference by a majority of ¾ of all Contracting Parties.

3. Position to be taken on Euratom’s behalf

The Commission proposes that the Member States that are parties to the ECT take, as regards matters falling under the Euratom Treaty, at the meeting of the Energy Charter Conference, the positions described below.

3.1. Regarding the adoption of an amendment to Article 49 ECT (CC 760 REV2)

The designation of a new depositary following the effective withdrawal of the Portuguese Republic from the ECT is essential for the institutional functioning of the ECT to which Euratom and several Member States are parties. The amendment to Article 49 ECT designating the Secretariat as a new depositary is integrated in the modernised ECT package on which the Charter Conference is to vote on 3 December 2024.

The adoption of this amendment to the ECT does not, in principle, have legal effects. Under international law, it is not equivalent to a signature but to the initialling of the negotiated text.

As a result, the Commission proposes that Member States take a position, as regards matters falling under the Euratom Treaty, at the Energy Charter Conference, not preventing the adoption of the proposed amendment to Article 49 ECT. This position will complement the Council Decision (Euratom) 2024/1645 of 30 May 20245.

3.2. Regarding the approval of a new understanding with respect to Article 49 ECT on the roles of the Energy Charter Secretariat (CC 762 REV2)

The new understanding intends to clarify the different roles of the Secretariat under the ECT. On the one hand, the Secretariat performs its functions of a secretariat pursuant to Article 35 ECT. On the other hand, it is to undertake the role of depositary pursuant to amended Article 49 ECT, once adopted. The new understanding will be integrated in the modernised ECT package on which the Charter Conference is to vote on 3 December 2024.

The adoption of an understanding does not, in principle, have legal effects. Under international law, it is not equivalent to a signature but to the initialling of the negotiated text.

As a result, the Commission proposes that Member States take a position, as regards matters falling under the Euratom Treaty, at the Energy Charter Conference, not preventing the approval of the proposed new understanding with respect to Article 49 on the roles of the Energy Charter Secretariat. This position will complement the Council Decision (Euratom) 2024/1645 of 30 May 20246.

3.3. Regarding the approval of a Decision on the Designation of the Energy Charter Secretariat as a Depositary under Article 49 ECT in the interim period as of 2 February 2025 (CC 814)

The self-standing Decision of the Energy Charter Conference on the designation of the Energy Charter Secretariat as an interim depositary of the ECT aims to ensure uninterrupted functioning of the ECT in the period following on the withdrawal of the Portuguese Republic from the ECT and the entry into force of the modernised ECT. Therefore, it sets out that the Secretariat should assume its function of depositary to the ECT as of 2 February 2025, i.e. the date on which the current depositary, the Government of Portuguese Republic ceases to perform this function.

As a result, the Commission proposes that the Member States take a position not preventing the approval of the self-standing Decision concerning the establishment of the Energy Charter Secretariat as depositary of the ECT in the interim period as of 2 February 2025.


Bearing in mind that the withdrawal of the EU and Euratom from the ECT was notified to the ECT depositary on 27 June 2024, it is expected that Euratom and the EU, while still being Contracting Parties to the ECT at the time of vote on the above-mentioned decisions of the Energy Charter Conference, will neither be present nor voting. Therefore, this proposal sets out the position to be taken by the Member States that remain Contracting Parties to the ECT at the meeting of the Energy Charter Conference scheduled for 3 December 2024. This is without prejudice to the division of competences between the Union and its Member States.

4. Legal basis

4.1. Principles

The Euratom Treaty contains no provision equivalent to Article 218(9) TFEU for Council decisions establishing the positions to be adopted on the Union’s behalf in a body set up by an agreement, when that body is called upon to adopt acts having legal effects. When a body set up by an agreement concluded by Euratom, such as the ECT, adopts acts having legal effects, the procedures provided in Article 101 of the Euratom Treaty apply.

Article 101(1) Euratom Treaty provides that: ‘The Community may, within the limits of its powers and jurisdiction, enter into obligations by concluding agreements or contracts with a third State, an international organisation or a national of a third State’.

Article 101(2) Euratom Treaty provides that: ‘Such agreements or contracts shall be negotiated by the Commission in accordance with the directives of the Council; they shall be concluded by the Commission with the approval of the Council, which shall act by a qualified majority.

4.2. Application to the present case

The ECT is an international agreement to which, inter alia, Euratom is a party.

On 3 December 2024, the Energy Charter Conference will be called upon to adopt acts having legal effects. These acts will be binding under international law. As a result, pursuant to Article 101(2) Euratom Treaty, they shall be subject to the approval of the Council under qualified majority.

The decisions to be adopted by the Energy Charter Conference to adopt, pursuant to Article 34 ECT, the proposed amendment and an understanding to Article 49 ECT constitute, in the particular circumstances of the case, acts having binding legal effects under international law because they are to be adopted simultaneously with the decision regarding the entry into force and provisional application of amendments and understandings to the text of the ECT, which obliges the Contracting Parties to provisionally apply these amendments and understandings on an agreed date if no contrary declaration is timely lodged.

The Decision to be adopted by the Energy Charter Conference to approve the Energy Charter Secretariat as a depositary of the ECT in the interim period as of 2 February 2025 also constitues an act having binding legal effect under international law. It constitues the legal basis for the Energy Charter Secretariat to ensure an uninterrupted functioning of the Energy Charter and will enter into force immediately upon its adoption, without the need for ratification, pursuant to Article 48 ECT.

Therefore, the procedural legal basis for the proposed decision is Article 101(2) Euratom Treaty as the Euratom Treaty contains no provision equivalent to Article 218(9) TFEU for decisions establishing the positions to be adopted on the Union’s behalf in a body set up by an agreement.

5. Publication of the envisaged act

As the decisions of the Energy Charter Conference will amend the ECT, its Understandings, Declarations and Decisions and will designate a new depositary under Article 49 ECT in the interim period until the entry into force of the modernised ECT, it is appropriate to publish them in the Official Journal of the European Union after their adoption.
