taxa de carbono — an addition to fuel duty for carbon emissions
The second tax component in the price of a litre of fuel, alongside ISP duty itself. It is calculated from carbon dioxide emissions and recalculated once a year. For the week from 31 August 2026 it is €0.1591 per litre of petrol and €0.1733 per litre of diesel — higher for diesel because burning a litre of it produces more carbon dioxide. It does not appear as a separate line on the receipt: it is built into the price at the pump, and VAT is charged on top of it too.
Where you come across it. Fuel price breakdowns, conversations about why a litre costs so much, DGEG tables on the taxes included in the price.
The government's temporary discount reduces only ISP; it does not touch the carbon tax.
