History of Carbon Tax

The first time we had a Carbon Tax in Ireland was back in the 2010 Budget . It was first introduced at a rate of  €15 Euro per Tonne. (But not on solid fuels.)
The Carbon Tax was then increased to €20 a tonne in the 2012 Budget –  which was a 66% increase.
(Don’t forget – VAT is charged on top of the Carbon Tax too).

Carbon Tax was first added to solid fuels in May 2013 at a rate of €10 per tonne. This was doubled in May 2014 to fall in line with other fuels.

It was proposed that the carbon tax would be increased in 2019 by 50% to €30 a tonne – but this didn’t happen.

In Ireland, prior to Budget 2020 the carbon tax was levied at €20 per tonne of CO2. On 8th October 2019 – The carbon tax on diesel and petrol was increased to €26 per tonne. This resulted in a price rise of about 2c per litre. The carbon tax on other fuels was increased to €26 a tonne from May 1st  2020.

From Oct 12th 2022 Carbon Tax was increased on auto fuels by €7.50 per tonne of carbon dioxide emitted, from €41.00 to €48.50. This was offset by a levy reduction so that it did not result in a price increase. For all other fuels, the carbon tax will increased from 1 May 2023. It will be €56.00 from 11th October 2023

Carbon Tax in Ireland will continue to move towards €100 per tonne in 2030.
