Carbon tax
Introduction
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.

Rates

Carbon tax is paid by the supplier of the fuel.
