Carbon tax


There is a carbon tax on fuel supplied in Ireland. The tax is based on the amount of carbon dioxide that the fuel emits when it is used.

The Solid Fuel Carbon Tax applies to coal and peat.

The Natural Gas Carbon Tax applies to natural gas supplied to consumers.

Natural gas supplied as fuel in a motor vehicle is called 'vehicle gas' and is instead liable to Mineral Oil Tax, part of which is a carbon charge.

The Mineral Oil Tax Carbon Charge also applies to petrol, auto-diesel and marked gas oil. You can see how much of the Mineral Oil Tax on fuel is carbon tax.

Budget 2024

It was announced that Carbon Tax will increase by €7.50 per tonne of carbon dioxide emitted, from €48.50 to €56.00. This applies from 11 October 2023 for auto fuels. For all other fuels, the carbon tax will increase from 1 May 2024.


The current rate of carbon tax is €48.50 per tonne of carbon dioxide emitted.

Carbon tax is paid by the supplier of the fuel.
