COUNCIL DECISION

on the position to be taken on behalf of the European Union in the Joint Committee established by the Agreement between the European Union and the Swiss Confederation on the linking of their greenhouse gas emissions trading systems as regards amending Annex I to the Agreement

(Text with EEA relevance)


EXPLANATORY MEMORANDUM

1.Subject matter of the proposal

This proposal concerns the decision establishing the position to be taken on the Union's behalf in the Joint Committee established by the Agreement between the European Union and the Swiss Confederation on the linking of their greenhouse gas emissions trading systems, as regards amending Annex I to the Agreement

2.Context of the proposal

2.1.The Agreement between the European Union and the Swiss Confederation on the linking of their greenhouse gas emissions trading systems

The Agreement between the European Union and the Swiss Confederation linking their greenhouse gas emissions trading systems 1 (‘the Agreement’) connects the EU Emissions Trading System (EU ETS) with the Emissions Trading System of Switzerland, by allowing allowances issued in one system to be traded and used for compliance in the other one. The Agreement entered into force on 1 January 2020.

2.2.The Joint Committee

The Joint Committee, established by Article 12 of the Agreement, is responsible for administering the Agreement and ensuring its implementation. It can decide to adopt new annexes to the Agreement or amend existing ones.

Article 13(2) of the Agreement provides that the Joint Committee may decide to adopt a new Annex or to amend an existing Annex to the Agreement.

2.3.The envisaged act of the Joint Committee

During its eighth meeting, which will be held in 2025, or earlier by means of the written procedure pursuant to Article 8(4) of the Rules of Procedure of the Joint Committee 2 , the Joint Committee is to adopt a decision regarding amendments to Annex I to the Agreement (‘the envisaged act’).

The purpose of the envisaged act is to align the essential criteria laid down in Annex I to updated legislation in both the European Union and the Swiss Confederation.

The envisaged act will become binding on the Parties in accordance with Article 13(2) of the Agreement. Furthermore, and in accordance with Article 12(3) of the Agreement, decisions taken by the Joint Committee in the cases provided for in this Agreement will, upon their entry into force, be binding on the Parties.

3.Position to be taken on the Union's behalf

The Council Decision based on this proposal from the Commission determines the position of the European Union on the Decision of the Joint Committee to be taken on amending Annex I.

Amendments to Annex I to the Agreement are necessary in view of the changes to the regulatory environment that evolved in both the European Union and Switzerland since the last amendments in Decision No 1/2023 of the Joint Committee 3 . The European Parliament and the Council adopted changes 4 to Directive 2003/87/EC 5 with a view to determining an appropriate contribution of the emissions trading system of the EU to the emissions reduction target by 2030 laid down in Regulation (EU) 2021/1119 of the European Parliament and of the Council 6 . These changes have to be reflected in Annex I to the Agreement to maintain compatibility and market integrity of the linked systems, avoid distortion of competition between as well as carbon leakage from the linked systems.

In part A (stationary installations) of Annex I, the relevant changes to the text of the EU column that is meant to demonstrate compliance with the essential criteria following the adoption of the revised version of Directive 2003/87/EC 7  mainly concern editorial adaptations with respect to the entry into force of the relevant legal texts on the EU side (amendments to essential criteria no 2, 3, 6, 10, 11, 12, 13) and updates of the legal references (amendments to essential criteria no 5 and 10). Only the text of criterion 4 has been amended with a view to representing the outcome of the revised Directive 2003/87/EC 8  in both columns of the EU and Switzerland. All other amendments to the column of Switzerland in Part A of Annex I are editorial adaptations with respect to the entry into force of the relevant legal texts.

As for Part B (aviation operators) of Annex I, compliance of the text in the column of the EU with the essential criteria requires changes with respect to the entry into force of the relevant legal provisions (criteria 12 and 14) and, in addition, updating the legal references (criteria 2, 4, 5 and 7). Furthermore, the text of criteria 4, 11 and 12 in the EU column has been adjusted to correctly depict the outcome of the revision of Directive 2003/87/EC 9 . For the same reason, the title of essential criteria 8 has been changed and the text in the EU column accordingly adjusted. This also goes for criterion 6, where the columns of the EU and Switzerland have been merged and a common text introduced.

In the Swiss column of Part B, editorial changes with respect to the entry into force of the relevant Swiss legislation became necessary for essential criteria 2, 5, 13, 14 and 15. This also applies to criteria 4, 8 and 12, which, on top, show an update of the legal reference. Furthermore, like in the EU column, the texts of criteria 4, 7 and 11 of the Swiss column have been adjusted to mirror the approach described in the EU column.

4.Legal basis

4.1.Procedural legal basis

4.1.1.Principles

Article 218(9) of the Treaty on the Functioning of the European Union (TFEU) provides for 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, with the exception of acts supplementing or amending the institutional framework of the agreement.’

4.1.2.Application to the present case

The Joint Committee is a body set up pursuant to Article 12 of the Agreement.

The act which the Joint Committee is called upon to adopt constitutes an act having legal effects. The envisaged act will be binding under international law in accordance with Article 12(3) of the Agreement.

The envisaged act does not supplement or amend the institutional framework of the Agreement.

Therefore, the procedural legal basis for the proposed decision is Article 218(9) TFEU.

4.2.Substantive legal basis

4.2.1.Principles

The substantive legal basis for a decision under Article 218(9) TFEU depends primarily on the objective and content of the envisaged act in respect of which a position is taken on the Union's behalf.

4.2.2.Application to the present case

The main objective and content of the envisaged act relate to environment.

Therefore, the substantive legal basis of the proposed decision is Article 192(1) TFEU.

4.3.Conclusion

The legal basis of the proposed decision should be Article 192(1) TFEU, in conjunction with Article 218(9) TFEU.

5.Publication of the envisaged act

As the act of the Joint Committee will amend Annex I to the Agreement, it is appropriate to publish it in the Official Journal of the European Union after its adoption.

DECISION No 1/2025 OF THE JOINT COMMITTEE ESTABLISHED BY THE AGREEMENT BETWEEN THE EUROPEAN UNION AND THE SWISS CONFEDERATION ON THE LINKING OF THEIR GREENHOUSE GAS EMISSIONS TRADING SYSTEMS

of …

as regards the amendment of Annex I to the Agreement

THE JOINT COMMITTEE,

Having regard to the Agreement between the European Union and the Swiss Confederation on the linking of their greenhouse gas emissions trading systems 1 (hereinafter ‘the Agreement’), and in particular Article 13(2) thereof,

Whereas:

(1)The adoption of Decision No 2/2019 of the Joint Committee of 5 December 2019 fulfilled the conditions for linking set out in the Agreement and enabled the Agreement to enter into force on 1 January 2020.

as in force on 1 January 2025.

The linear reduction factor is 6,4 % in 2025 as an adjustment to result in the same level of reduction of the cap for the period 2021 to 2025 as determined by the linear reduction factor of the EU ETS. As of 2026, the linear reduction factor is 4.3% per year and 4,4% as from 2028. It will apply to all sectors covered by the Swiss ETS.

5.

Market stability mechanism

In 2015, the EU introduced the Market Stability Reserve (Decision (EU) 2015/1814), the operation of which was reinforced by Directive (EU) 2018/410 and Directive (EU) 2023/959.

The EU legislation provides that, by 15 May each year and starting in 2017, the Commission shall publish the total number of allowances in circulation (TNAC). This figure determines whether some of the allowances intended to be auctioned should be placed into the reserve or be released from the reserve.

-Article 19(6) of the CO2 Act

-Article 48(1bis) and (5) of, and Annex 8 point 2 to the CO2 Ordinance,

as in force on 1 January 2025.

The Swiss legislation provides for a reduction in auction volume conditional on the total number of allowances in circulation. In addition, the emission allowances which are not assigned to an auction are cancelled at the end of the trading period. 

6.

The level of market oversight of the ETS shall be at least as stringent as the ones in:

-    Directive 2014/65/EU of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments and amending Directive 2002/92/EC and Directive 2011/61/EU (MIFID II)

-    Regulation (EU) No 600/2014 of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments and amending Regulation (EU) No 648/2012 (MIFIR)

-    Regulation (EU) No 596/2014 of the European Parliament and of the Council of 16 April 2014 on market abuse (market abuse regulation) and repealing Directive 2003/6/EC of the European Parliament and of the Council and Commission Directives 2003/124/EC, 2003/125/EC and 2004/72/EC (MAR)

-    Directive 2014/57/EU of the European Parliament and of the Council of 16 April 2014 on criminal sanctions for market abuse (market abuse directive) (CS‑MAD)

-    Directive (EU) 2015/849 of the European Parliament and of the Council of 20 May 2015 on the prevention of the use of the financial system for the purposes of money laundering or terrorist financing, amending Regulation (EU) No 648/2012 of the European Parliament and of the Council, and repealing Directive 2005/60/EC of the European Parliament and of the Council and Commission Directive 2006/70/EC (AMLD),

-    Federal Act on Combating Money Laundering and Terrorist Financing of 10 October 1997,

as in force on 1 January 2025.

Swiss financial market regulation does not define the legal nature of emission allowances. In particular, emission allowances are not qualified as securities in the Financial Markets Infrastructure Act and therefore are not tradeable on regulated trading venues. Because emission allowances do not qualify as securities, Swiss securities regulation does not apply to OTC emission allowances trading on secondary markets.

Derivative contracts qualify as securities according to the Financial Markets Infrastructure Act. This also includes derivatives that have emission allowances as their underlying instrument. OTC traded derivatives on emission allowances between non‑financial as well as financial counterparties is covered by the provisions in the Financial Market Infrastructure Act.

7.

Cooperation regarding market oversight

The Parties shall establish appropriate cooperation arrangements regarding market oversight. Those cooperation arrangements shall concern the exchange of information and the enforcement of obligations arising under their respective market oversight regime. The Parties shall inform the Joint Committee about any such arrangements.

Administration

The criteria laid down in Article 18a of Directive 2003/87/EC shall apply. To this effect and pursuant to Article 25a of Directive 2003/87/EC, Switzerland shall be considered as an Administering Member State as regards the attribution of the administration of aircraft operators to Switzerland and EU (EEA) Member States.

Pursuant to Article 25a of Directive 2003/87/EC, the competent authorities of the EU (EEA) Member States shall be responsible for all the tasks related to the administration of aircraft operators attributed to them, including the tasks relating to the ETS of Switzerland (e.g. the reception of verified emission reports covering both EU and Swiss aviation activities, administration of aircraft operators and accounts, compliance and enforcement).

The European Commission shall agree bilaterally with the Swiss competent authorities on handing over the relevant documentation and information.

In particular, the European Commission shall ensure the transfer to aircraft operators administered by Switzerland of the amount of free allocation of EU allowances.

In case of a bilateral agreement regarding the administration of flights operating in relation to the EuroAirport Basel‑Mulhouse‑Freiburg not involving any amendment to Directive 2003/87/EC, the European Commission shall, as appropriate, facilitate the implementation of such agreement, provided that this does not result in double counting.

Switzerland shall be responsible for the administration of aircraft operators:

-    with a valid operating licence granted by Switzerland, or

-    with the greatest estimated attributed aviation emissions in Switzerland under the linked ETS.

Swiss competent authorities shall be responsible for all the tasks related to the administration of aircraft operators attributed to Switzerland, including the tasks relating to the EU ETS (e.g. the reception of verified emission reports covering both EU and Swiss aviation activities, administration of aircraft operators and accounts, compliance and enforcement).

The Swiss competent authorities shall agree bilaterally with the European Commission on handing over the relevant documentation and information.

In particular, the Swiss competent authorities shall transfer to aircraft operators administered by the EU (EEA) Member States the amount of free allocation of Swiss allowances.

This is provided for in:

-Article 46d of, and Annex 14 to, the CO2 Ordinance,

as in force on 1 January 2025.

15.

Surrendering

When assessing compliance of aircraft operators on the basis of the amount of surrendered allowances, the competent authorities of the EU (EEA) Member States shall first account for emissions covered by the ETS of Switzerland and use the remaining amount of surrendered allowances to account for emissions covered by the EU ETS.

When assessing compliance of aircraft operators on the basis of the amount of surrendered allowances, the competent authorities of Switzerland shall first account for emissions covered by the EU ETS and use the remaining amount of surrendered allowances to account for emissions covered by the ETS of Switzerland.

This is provided for in:

- Article 55 (2bis) of the CO2 Ordinance

as in force on 1 January 2025.

16.

Legal enforcement

Parties shall enforce the provisions of their respective ETS in relation to aircraft operators that do not fulfil the obligations in the respective ETS, regardless of whether the operator is administered by an EU (EEA) competent authority or by a Swiss competent authority, in case enforcement by the authority administering the operator requires additional action.

17.

Administrative attribution of aircraft operators

Pursuant to Article 25a of Directive 2003/87/EC, the aircraft operator’s list published by the European Commission, in accordance with Article 18a(3) of Directive 2003/87/EC, shall specify the administering State, including Switzerland, for each aircraft operator.

Aircraft operators attributed to Switzerland for the first time after the entry into force of this Agreement shall be administered by Switzerland after 30 September of the year of attribution and once the provisional registry link is operational.

The two parties shall cooperate on sharing relevant documentation and information.

The attribution of an aircraft operator shall not affect the coverage of that aircraft operator by the respective ETS (i.e. an operator covered by the EU ETS that is administered by the Swiss competent authority shall have the same level of obligations under the EU ETS alongside its coverage under the ETS of Switzerland, and vice versa).

18.

Modalities for implementation

Any further modalities needed for the organisation of the work and cooperation within the one‑stop shop for aviation account holders shall be developed and adopted by the Joint Committee after signature of this Agreement, in accordance with Articles 12, 13 and 22 of this Agreement. These modalities shall apply from the date that this Agreement applies.
