A major report on taking action on climate change looks set to include a recommendation for a four-fold increase in the price of carbon by the year 2030.

A series of votes by TDs and Senators on the Oireachtas Climate Action Committee means the original text of their draft report will be retained.

The draft text reads: "The Minister for Finance should introduce legislation in 2019 that sets forth a carbon price trajectory that rises to at least €80  per tonne by 2030." The current price of carbon is €20 per tonne.

Fianna Fáil had proposed that this text be deleted. However with the Committee tied with 11 votes in favour and 11 votes against their amendment was lost.

The €80 per tonne figure is a recommendation of the state's Climate Change Advisory Council.

It is currently unclear if Fianna Fáil will support the draft report in totality, given its amendment on the green tax was defeated.

People Before Profit, which opposes a carbon tax, has already indicated that it is very likely to publish a minority report, as it would not support some of the measures in the draft report.

Around 40 other amendments to the climate action plan have been proposed, and the committee will now go through them chapter by chapter.

Among the issues which are still to be decided is whether revenue from a green tax should be given back as a rebate to citizens who act on climate change, or whether it would be better used to address fuel poverty or fund the retrofitting of old buildings. 

Earlier today, Green Party leader Eamon Ryan conceded that the committee's work had hit "a speed bump" and publication could be delayed by at least another week.

The delay related to those Fianna Fáil concerns about the carbon tax hikes, as well as the party's desire for more to be done to address fuel poverty.

It is currently unclear when the final report will be published. Two earlier deadlines were missed, and tomorrow's deadline looks unlikely to be met.

The final report will influence the Government's approach to carbon tax increases which the Taoiseach said at the weekend are "on the table" for the next budget.
