What is the Carbon Tax?

As a gas customer in Ireland, Carbon Tax will appear on your gas bill.

The Government's 2010 Finance Bill introduced a carbon tax which is applied to mineral oils, natural gas and solid fuels supplied for combustion in Ireland.

From 4th October 2026, the tax for natural gas is €48.50 per tonne of carbon dioxide (CO2) emitted. All gas suppliers must apply the carbon tax to customer's bills.

You'll see the carbon tax rate on your bill as 0.0877 cent/kWh (0.1251 cent/kWh incl.VAT).

This is subject to a VAT rate of 9%.
