ANNEX

Parts A and B of Annex I to the Agreement are replaced by the following:

‘A. Essential criteria for stationary installations

	Essential criteria	In the EU ETS	In the ETS of Switzerland
1.	Mandatory nature of the participation in the ETS	Participation in the ETS shall be mandatory for the installations carrying out the activities and emitting the greenhouse gases (“GHG”) listed below.	Participation in the ETS shall be mandatory for the installations carrying out the activities and emitting the GHG listed below.
2.	The ETS shall cover at least the activities set out in:	Annex I to Directive 2003/87/EC, as in force on 1 January 2025.	Article 40(1) of, and Annex 6 to, the CO2 Ordinance, as in force on 1 January 2025.
3.	The ETS shall cover at least the GHGs set out in:	Annex II to Directive 2003/87/EC, as in force on 1 January 2025.	Article 1(1) of the CO2 Ordinance, as in force on 1 January 2025.
4.	A cap shall be set for the ETS, which is at least as stringent as the one in:	Articles 9 and 9a of Directive 2003/87/EC, as in force on 1 January 2025. The linear reduction factor is 4,3 % per year from 2024 to 2027 and 4,4 % as from 2028. It will apply to all sectors in accordance with Directive 2003/87/EC, as in force on 1 January 2025.	Article 18(1) and (2) of the CO2 Act Article 45(1) of, and Annex 8 point 1 to, the CO2 Ordinance, 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 Directives (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), as in force on 1 January 2025.	Federal Act on the Swiss Financial Market Supervisory Authority of 22 June 2007 Federal Act on Financial Market Infrastructures and Market Conduct in Securities and Derivatives Trading of 19 June 2015 Federal Act on Financial Institutions of 15 June 2018 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.
8.	The qualitative limits for international credits shall be at least as stringent as those set out in:	No entitlements to use international credits are provided for in Union law from 2021 onwards.	No entitlements to use international credits are provided for in Swiss law from 2021 onwards.
9.	The quantitative limits for international credits shall be at least as stringent as those set out in:	No entitlements to use international credits are provided for in Union law from 2021 onwards.	No entitlements to use international credits are provided for in Swiss law from 2021 onwards.
10.	Free allocation shall be calculated on the basis of benchmarks and adjustment factors. Allowances which are not allocated free of charge shall be auctioned or invalidated. To this end, the ETS shall meet at least:	Articles 10, 10a, 10b and 10c of Directive 2003/87/EC Commission Implementing Regulation (EU) 2021/447 of 12 March 2021 determining revised benchmark values for free allocation of emission allowances for the period from 2021 to 2025 pursuant to Article 10a(2) of Directive 2003/87/EC of the European Parliament and of the Council, as applicable in the period from 1 January 2021 to December 2025 Directive (EU) 2023/959 of the European Parliament and of the Council of 10 May 2023 amending Directive 2003/87/EC establishing a system for greenhouse gas emission allowance trading within the Union and Decision (EU) 2015/1814 concerning the establishment and operation of a market stability reserve for the Union greenhouse gas emission trading system Commission Delegated Regulation (EU) 2024/873 of 30 January 2024 amending Delegated Regulation (EU) 2019/331 as regards transitional Union-wide rules for harmonised free allocation of emission allowances Commission Delegated Decision (EU) 2019/708 of 15 February 2019 supplementing Directive 2003/87/EC of the European Parliament and of the Council concerning the determination of sectors and subsectors deemed at risk of carbon leakage for the period 2021 to 2030 any cross-sectoral correction factor in the EU ETS in 2021-2025 or 2026-2030, Commission Implementing Regulation (EU) 2025/772 of 16 April 2025 amending and correcting Implementing Regulation (EU) 2019/1842 laying down rules for the application of Directive 2003/87/EC of the European Parliament and of the Council as regards further arrangements for the adjustments to free allocation of emission allowances due to activity level changes. as in force on 1 January 2025.
