Two Ways Carbon Gets Priced into Fuel
Carbon costs reach pump prices through two distinct channels:
- Explicit carbon taxes: A government sets a price per tonne of CO₂ and levies it on fuel at the distribution stage. Sweden, Germany, Finland, Ireland, and Norway are the main examples. The tax appears in the wholesale fuel cost before any retail markup.
- Cap-and-trade systems (ETS): Governments set a cap on total emissions and issue tradeable allowances. Fuel distributors (under ETS2) or refiners and power generators (under ETS1) must hold allowances covering their emissions. The cost of allowances passes through to wholesale prices.
The World Bank Carbon Pricing Dashboard tracks all active instruments globally — as of 2024, carbon pricing covers about 23% of global greenhouse gas emissions, up from 15% in 2020. The ICAP ETS Map shows every active emissions trading system worldwide.
The EU ETS1: Indirect Effect on Pump Prices
The existing EU Emissions Trading System (ETS1) covers power generation, heavy industry, and aviation — not road transport or heating. Its indirect pump price effect comes through:
- Power generation costs (higher electricity prices = costlier public EV charging)
- Refinery operating costs (refineries buy ETS allowances for their process emissions)
- Industrial feedstock costs that ripple through supply chains
At the 2023 average ETS price of ~€85/tonne, refinery emissions compliance adds roughly €0.03–0.05/litre to wholesale petrol costs — a modest contribution, but one that didn't exist before 2021 when ETS prices were below €30/tonne.
EU ETS2: The Big Change Coming in 2027
The EU ETS2 Directive (2023/959) extends carbon pricing directly to road transport and buildings from 2027. Fuel distributors — companies that supply heating fuel and road transport fuel to end users — must surrender ETS2 allowances for every tonne of CO₂ their fuels emit when burned.
The European Commission projects an initial ETS2 carbon price of €40–55/tonne in 2027. At €45/tonne:
- Petrol: +€0.10/litre (petrol emits ~2.28 kg CO₂/litre)
- Diesel: +€0.12/litre (diesel emits ~2.65 kg CO₂/litre)
- LPG: +€0.08/litre (lower carbon intensity)
A price stability mechanism (MSR) prevents the ETS2 carbon price exceeding €45/tonne before 2030. If prices spike above this level, additional allowances are released. This limits the pump price shock in transition years but also limits the decarbonisation signal. The European Parliament's ETS2 report provides the full legislative background.
ETS2 revenues fund the Social Climate Fund (Regulation 2023/955), which redistributes support to low-income households and vulnerable transport users. EUR 86.7 billion is earmarked for 2026–2032. The fund is intended to offset the regressive impact of carbon pricing on those who spend a higher share of income on fuel.
National Carbon Taxes Already in the Pump Price
Fourteen European countries already levy explicit national carbon taxes on transport fuels on top of EU minimum excise duty. Key examples:
| Country | Carbon tax rate (2024) | Approx. petrol impact (€/litre) |
|---|---|---|
| Sweden | SEK 1,330/tCO₂ (~€117) | +€0.27 |
| Norway | NOK 952/tCO₂ (~€85) | +€0.19 |
| Switzerland | CHF 120/tCO₂ (~€124) | +€0.28 |
| Finland | €88/tCO₂ | +€0.20 |
| Netherlands | €61/tCO₂ | +€0.14 |
| Germany | €45/tCO₂ | +€0.10 |
| Ireland | €56/tCO₂ | +€0.13 |
| France | €44.6/tCO₂ | +€0.10 |
These rates are a major reason why Scandinavian and Swiss petrol prices are among Europe's highest even before general excise duty. The OECD Taxing Energy Use database provides comparable cross-country effective carbon rates.
Non-European Carbon Pricing and Fuel
Carbon pricing is not exclusively European. Canada's federal carbon tax, raised to CAD 80/tonne CO₂ in 2024 (rising to CAD 170 by 2030), adds directly to Canadian pump prices. Environment Canada publishes the schedule. Singapore, New Zealand, and several other advanced economies have carbon pricing that touches transport fuels.
China's national ETS covers power generation but not transport — yet. The ICAP China ETS factsheet notes that transport is under consideration for future inclusion. Given China's size, its eventual carbon price on road transport would be one of the biggest single policy changes in global fuel demand.
What This Means for Pump Price Comparisons
Carbon pricing is becoming an increasingly important reason why pump prices differ between countries, on top of the traditional drivers — crude costs, refining margins, excise duty, VAT. When you compare prices in our fuel price explorer, countries with high carbon taxes (Sweden, Norway, Finland) will appear more expensive partly because of their climate policy choices, not just legacy tax structures.
From 2027, the gap between EU member states with and without national carbon taxes will narrow, as ETS2 creates a floor across all 27. Countries currently relying only on the EU minimum excise — several Eastern European states — will see the biggest proportional pump price impact. Our guide on excise duty and the pump price breakdown guide provide the framework for understanding how these costs layer.
Frequently Asked Questions
How much does the EU carbon price add to petrol costs?
The existing EU ETS1 (power/industry) adds €0.03–0.05/litre indirectly via refinery compliance costs. The EU ETS2 (from 2027) will add approximately €0.10/litre for petrol at an estimated €45/tonne initial price. See the ETS2 Directive and World Bank Carbon Pricing Dashboard.
Which European countries have national carbon taxes on fuel?
Sweden, Norway, Switzerland, Finland, Netherlands, Germany, Ireland, France, and several others. Sweden has the world's highest at ~€117/tonne. The OECD Taxing Energy Use database has comparable effective rates for all OECD countries.
What is the EU ETS2 and when does it start?
EU ETS2 is a new carbon trading system covering road transport and buildings, starting in 2027. Fuel distributors must hold allowances for the CO₂ in fuels they supply. European Commission ETS pages and the ETS2 Directive text have full detail. A Social Climate Fund (EUR 86.7 bn) will support vulnerable households.
