CO2 Sanction Vehicle Registration 2026: What Buyers Need to Know

From 2026, no new car can be registered in Switzerland while an outstanding CO2 sanction remains unpaid. The Swiss Federal Office of Energy (SFOE) calculates the penalty, the Federal Roads Office (FEDRO) verifies it digitally, and the buyer bears the consequences if the dealer is not prepared.

Key Takeaways

• 2026 target value: 93.6 g CO2/km for passenger cars (weighted fleet average)
• Sanction amount: CHF 95 per gram of CO2 above the target value, from 0.1 g of excess
• Responsible authorities: SFOE calculates and invoices; FEDRO verifies at registration
• eCoC: Since 1 January 2026, the Certificate of Conformity has been fully digital (Eucaris database)
• Who pays: importers and dealers, but the cost is regularly passed on to the purchase price
• Exceptions: battery-electric and hydrogen vehicles pay no CO2 sanction

How the CO2 Sanction System Works in Switzerland

The system is clearer than often presented, but with a frequently underestimated penalty rate: CHF 95 per gram of CO2/km above the individual target value, linear, without tiers.

The SFOE sets an individual target value for each large importer, based on the weighted average vehicle weight of its registered fleet. The 2026 base value is 93.6 g CO2/km. If a vehicle exceeds the value applicable to that importer, each gram of excess triggers a CHF 95 sanction.

For small-volume importers (fewer vehicles imported per year), the calculation is done individually via the SFOE online tool. They also need an SFOE certificate and a FEDRO confirmation before the vehicle can be registered.

Sanction Table: 2026 Example Calculation for Passenger Cars

| Vehicle (example) | CO2 emissions | Excess above 93.6 g | CO2 sanction | |-------------------|---------------|---------------------|--------------| | Battery-electric (BEV) | 0 g/km | 0 g | CHF 0 | | Efficient compact | 90 g/km | 0 g | CHF 0 | | Petrol compact sedan | 110 g/km | 16.4 g | CHF 1'558 | | Petrol SUV | 150 g/km | 56.4 g | CHF 5'358 | | Pick-up / large SUV | 200 g/km | 106.4 g | CHF 10'108 |

Source: SFOE, sanction of CHF 95/g from 0.1 g of excess. 93.6 g/km target value as base; individual target values per importer can vary slightly.

The math makes it tangible: anyone buying a mid- or high-consumption petrol or diesel vehicle pays several thousand francs of CO2 sanction indirectly, even if it does not appear as a separate line on the invoice.

Who Is Responsible: SFOE or FEDRO?

A common mix-up: FEDRO (Federal Roads Office) is not the authority that calculates the sanction. The roles are clearly split:

• SFOE (Federal Office of Energy): calculates the CO2 sanction, invoices the importer, issues the confirmation
• FEDRO (Federal Roads Office): manages digital vehicle registration, retrieves eCoC data from the European Eucaris database
• FOEN (Federal Office for the Environment): sets the regulatory framework for Switzerland's CO2 rules on vehicles

For registration at the cantonal road traffic office, the rule is clear: the vehicle can only be registered once a due sanction has been paid and the SFOE confirmation is available.

What the eCoC System Changes from 2026

Since 1 January 2026, FEDRO has retrieved the electronic Certificate of Conformity (eCoC) directly from the European Eucaris database. The document contains the vehicle's official CO2 rating and is checked automatically.

For many new vehicles, especially passenger cars produced in the EU, registration becomes purely administrative: no more physical document inspection at the road traffic office, the data flows in digitally.

For direct importers from the EU, a separate verification process remains, including the SFOE certificate and FEDRO confirmation.

Importer Pool: How Large Manufacturers Calculate

Large importers are subject to a fleet obligation in Switzerland. Their individual CO2 target value comes from a weighted formula that takes fleet weight into account:

Permissible specific emission = 93.6 + a x (kerb weight - Mt-2) g CO2/km

In practice: fleets with heavier vehicles have a slightly higher target value. SFOE calculates and sends the invoice automatically based on FEDRO registration data; the importer does not have to submit own data.

Importers can join emission communities (pools) to meet fleet targets jointly, similar to EU law.

Electric Vehicles and Hybrids: Clear Differences

Battery-electric vehicles (BEV) and hydrogen fuel-cell vehicles (FCEV) are fully exempt from the CO2 sanction. With zero grams of CO2 at the tailpipe, they do not weigh on the importer's fleet average.

For plug-in hybrids (PHEV), the situation has been more complex since 2026: the counting rules in the fleet calculation were tightened. Many plug-in models weigh more in the official CO2 rating than their consumption figures would suggest. The reference is the WLTP CO2 value on the eCoC: check this figure before relying on consumption estimates.

Impact on Purchase Price and Leasing

Formally, the CO2 sanction is paid by the importer. In practice, it is regularly passed on to the purchase price, often without a separate line on the invoice. For buyers:

• High-emission new vehicle: the price likely already contains the passed-on sanction
• Leasing: the sanction influences residual value and monthly rate; ask the dealer explicitly
• Direct EU import: own responsibility for SFOE confirmation and sanction payment

If you are leasing, clarify before signing whether the CO2 sanction is included in the calculated vehicle price: this has a direct impact on your monthly rate.

Frequently Asked Questions

Does the CO2 sanction apply to used cars?

No. The CO2 sanction only applies to the first registration of new vehicles in Switzerland. Used vehicles and already-registered vehicles are not affected, including when buying a pre-owned vehicle from abroad if it was already registered there.

How high is the CO2 sanction in Switzerland in 2026?

CHF 95 per gram of CO2/km that the importer exceeds its individual target value, from an excess of 0.1 g. The amount is linear, not tiered. (Source: SFOE)

What is the 2026 CO2 target value for passenger cars?

The base value is 93.6 g CO2/km. Individual target values can vary slightly depending on the importer's fleet weight. (Source: SFOE)

What happens if the dealer has not paid the sanction before delivery?

The vehicle cannot be registered. As a buyer, you have the right to require the dealer to settle payment before the agreed delivery date. In case of excessive delay, withdrawing from the purchase contract may be an option, depending on the agreed terms.

Can I pay the CO2 sanction myself for a direct import?

Yes. For direct imports from the EU you file an application with SFOE via egov.swiss. SFOE calculates the sanction and issues the confirmation after payment. You need this confirmation for registration at the cantonal road traffic office.

Are electric vehicles fully exempt?

Yes, fully. Battery-electric and hydrogen vehicles pay no CO2 sanction, since they produce zero CO2 emissions at the tailpipe.

How does the situation change for plug-in hybrids from 2026?

For 2026, stricter counting rules apply: plug-in hybrids weigh more in the official fleet calculation than their consumption values suggest. The reference is the WLTP CO2 value on the eCoC, not real-world consumption. Check this figure before buying a plug-in model.

What does the eCoC mean for registration from 2026?

Since 1 January 2026, FEDRO retrieves the Certificate of Conformity digitally from the European Eucaris database. For many new vehicles, physical document inspection at the road traffic office is no longer required. Any due CO2 sanction must be settled before registration is released.

Outlook 2030: Where the Target Value Is Heading

The base value of 93.6 g CO2/km will tighten further by 2030, in line with EU regulation. Vehicles bought in 2026 will still be on the road in 2030. Choosing a low-emission vehicle today positions you better for:

• Future penalty costs at the dealer/importer (which flow into the purchase price)
• Resale value in a market with tightening standards
• Potential cantonal tax incentives for low-emission vehicles
