The rate of carbon tax will increase today with consumers of carbon fuels set to pay more.
The tax is applied per tonne of carbon dioxide emitted by carbon fuels and it increases by €7.50 bringing the rate to €56 per tonne.
The increase will add €19.40 to the cost of filling a 900-litre tank of kerosene home heating oil.
Users of coal and briquettes for heat will also see prices rise.
Carbon tax on a 40kg bag of coal will add an extra 90c per bag and a bale of briquettes will rise by 20c.
However, petrol and diesel prices will not rise, as the carbon tax increase was applied to those products last October.
Sinn Fein Finance Spokesman, Pearse Doherty, described the move as a blow to households that continue to struggle with high energy costs.
“When the government should be making all efforts to reduce living costs for households, instead they are increasing them,” he said.
