Written answers

I am advised by Revenue that the projected yield from the increase to a charge of €78.50 per tonne of carbon dioxide emitted and, therefore, the estimated cost of deferring this increase for a further year, is shown in the following table. The Deputy should note that under the current schedule propellant fuels, including petrol and diesel, will increase to the €78.50 per tonne rate with effect from the 14 October 2026, while other fuels subject to the Carbon Charge will increase to this rate from the 01 May 2027.
