The Climate Action Minister will hold high-stakes talks with Agriculture Minister Charlie McConalogue later to agree a reduction in greenhouse gas emissions.
Last year government announced plans to cut emissions in agriculture by between 22 and 30 percent by 2030, under its Climate Action Plan.
Today's negotiations are aimed at reaching agreement on a precise figure that can be brought to Cabinet next week for sign-off.
Eamon Ryan's seeking 30 percent, however his Cabinet colleague's pushing for 22, amid pressure from rural Fianna Fail and Fine Gael backbenchers.
Junior Agriculture Minister and Green Party TD, Pippa Hackett, says government wants to get the balance right.
