A carbon tax is a tax on the use of fossil fuels such as oil, petrol, diesel, gas, coal and peat.
Carbon tax increases are implemented annually under the 10-year carbon tax trajectory that was introduced in Finance Act 2020.
Carbon tax rate increases on petrol and auto-diesel are next legislated to occur on 9 October 2024 when the rate of carbon tax will increase from €56 to €63.50 per tonne of carbon dioxide emitted. This will add 2.1 cent per litre of petrol and 2.5 cent per litre of auto diesel, VAT inclusive.
Carbon Tax on solid fuel and gas will be increased in May 2025
Overall Cost of Carbon Tax on Fuels In May 2024 (Approximate)
- €6 on a 40kg bag of coal
- €1.30 cents on a bale of briquettes
- 15 cents on a litre of diesel/petrol
- €127 on the average household gas bill
- €141 on 900 litres of heating oil

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.
In 2020, legislation was introduced for a 10-year trajectory of carbon tax increases to bring the
charge per tonne of CO2 emmissions to €100 by 2030.
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.
On May 1st 2024 – the carbon tax on solid fuels increased to €56 per tonne of CO2
The carbon tax rates per tonne of fuel are:
- €147.49 on coal
- €102.68 on Peat Briquettes
Carbon Tax is also charged on Natural Gas . From May 1st 2024 the rate is €56 per tonne of Co2 which equates to €10.13 per MWh .
Carbon tax rate increases on petrol and auto-diesel are legislated to occur on 9 October 2024 when the rate of carbon tax will increase from €56 to €63.50 per tonne of carbon dioxide emitted. This will add 2.1 cent per litre of petrol and 2.5 cent per litre of auto diesel, VAT inclusive.
How Is Carbon Tax Spent?
Since Budget 2020, all carbon tax revenues above the €20 per tonne of carbon dioxide rate are ring-fenced. From a total of almost €5.3 billion in total carbon tax revenues, approximately €1.36 billion of carbon tax revenues have been deposited to the Central Fund, with a further €788 million forecast to be ring-fenced in 2024.
These funds are used to finance green initiatives and other climate-related policies such as home retrofits and addressing energy poverty.
