Farmers will be asked to cut their emissions by 25% under plans approved by Government leaders this evening.
The agriculture sector will have to eliminate a quarter of its emissions output over the next eight years.
Tense negotiations over the last few days had been at an impasse.
Agriculture Minister Charlie McConalogue was saying emissions should be cut by no more than 24%.
While Environment Minister Eamon Ryan was going no lower than 26%.
In the end, they've split the difference and Government leaders have approved a 25% reduction.
Ministers have been getting calls as part of an incorporeal Cabinet meeting this afternoon to approve the deal.
It's on the lower end of the 22 to 30% range initially approved by Government.
A press conference to announce the deal is expected in the coming hours.
