Two five-year plans aiming to cut Irish greenhouse gas emissions in half by the end of the decade has been released.
The Climate Change Advisory Council is targeting cuts of 4.8% a year up to 2025, followed by 8.4% annually to 2030.
Climate Action Minister Eamon Ryan says sector-by-sector targets will be published in the weeks ahead, and each "will need to play its part".
When ratified by the Oireachtas, the targets are to be made legally binding.
Chair of the expert panel, Marie Donnelly, says the smaller cuts in the first budget aren't a sign action is being delayed.
"The Council has spent quite a bit of time looking at the balance between the two carbon budgets, and the reason why we have put a greater emphasis on reduction in the second half is that we now urgently need to make the investment that will allow us to decarbonise.
"There is a lag time between investing and getting the benefit of the emissions reductions."
