- Switzerland
The Swiss Emissions Trading System (Swiss ETS) is mandatory for certain categories of companies — specifically, large industrial installations and aviation operators that exceed defined annual emission thresholds.
It was established under the Swiss CO₂ Act and CO₂ Ordinance, making participation a legal obligation for entities that meet the criteria. These include operators in sectors such as cement, refining, steel, chemicals, and large-scale combustion plants, as well as domestic and outbound flights within the European Economic Area covered by the Swiss–EU ETS link.
Exceptions and Voluntary Participation
However, the Swiss ETS does include limited exceptions and opt-in provisions:
Small emitters (installations below the mandatory emission threshold, typically <25,000 tonnes of CO₂ per year) are not automatically required to participate.
These smaller entities can voluntarily opt in to the ETS instead of paying the Swiss CO₂ levy, if they prefer to be part of the trading system.
Some sectors or processes that emit non-CO₂ greenhouse gases may fall outside the ETS but are still subject to other climate policies or levies.
In summary:
The Swiss ETS is mandatory for large emitters and aviation operators covered by the CO₂ Act, but small emitters may opt in voluntarily, and certain sectors remain exempt or regulated under different instruments such as the CO₂ levy.
Deep dive
What’s Required
The Swiss ETS is embedded within Switzerland’s Federal CO₂ Act (and associated CO₂ Ordinance) and applies to installations and aviation operators covered under Swiss climate legislation.
Covered entities must:
Monitor, report, and verify their CO₂ emissions annually under approved methodologies (CO₂, N₂O, and other regulated gases).
Hold and surrender emission allowances (Swiss allowances or linked EU allowances) equal to their verified emissions.
Participate in auctions or receive free allocation (based on benchmarks) for part of their allowances.
For new entrants or growth sectors, request allocations or participate in auctioning mechanisms.
Maintain an account in the Swiss Emissions Trading Registry (EHR) to record issuance, holding, trading, cancellation, surrendering, and transfers of units.
Comply with market rules (holding limits, linkages, registry transfers) as stipulated by Swiss ETS and linked EU ETS protocols.
Important Deadlines & Obligations
Entities must submit their emissions data and reports annually (typically by the end of March) and surrender allowances accordingly.
Regulatory adjustments to the CO₂ Act or Ordinance take effect according to legislative schedules, with transitional provisions as needed.
In the case of linkage with the EU ETS, allowance transfers between Swiss and EU registries generally occur daily on weekdays, with exceptions predefined in registry rules.
Free allocation benchmarks, auction schedules, and market stability rules are updated periodically under the CO₂ Ordinance.
Current Status
The Swiss ETS is enacted under Switzerland’s CO₂ Act and CO₂ Ordinance, which constitute the core legal basis for Swiss carbon regulation.
Since 1 January 2020, the Swiss ETS has been linked with the EU ETS, enabling mutual recognition and automatic transfer of allowances between Swiss and EU systems.
Covered sectors include industrial installations, stationary combustion, power plants, and aviation (domestic and outbound flights).
The Swiss ETS uses the same benchmarking rules as the EU ETS for covered installations.
Free allocation for aviation is being phased out (by 2026) in alignment with EU rules.
The Swiss ETS applies the same linear reduction factors as the EU ETS in many respects for the 2024–2030 period.
In March 2024, the Swiss Parliament approved a revised CO₂ Act (effective 1 January 2025), setting new sectoral targets and enhancing alignment with EU ETS rules.
Switzerland retains sovereignty over its ETS legal framework, but operates in coordination with EU rules under the linking treaty.
Penalties for Non-Compliance
Non-compliance with Swiss ETS responsibilities may entail:
Financial penalties and fines for failing to surrender sufficient allowances or missing reporting obligations.
Administrative sanctions, including restrictions on registry usage or disqualification from auctions.
Enforcement measures under the CO₂ Act (and Ordinance) for providing false data or breaching record-keeping rules.
Interest or recovery of missing units for late or incorrect submissions.
Regulatory oversight is performed by the Federal Office for the Environment (FOEN / FOEN/BAFU), which audits compliance and enforces penalties.
Examples of Known Violations
Publicly documented cases in Swiss ETS enforcement are limited. Regulatory reports note occasional non-compliance and surrender irregularities, but do not always disclose entity names or penalty amounts. Because the linking to the EU ETS is relatively recent and the Swiss system is smaller, high-profile enforcement cases are less frequently publicized.
"As of now, no well-known, publicly detailed penalties under the Swiss ETS with named parties and amounts are widely reported."
