The chair of the Climate Change Advisory Council has said that it will shortly make a recommendation to Government for an all-economy carbon budget to tackle carbon emissions across all sectors up to 2035.
Marie Donnelly said work is advanced in bringing forward a carbon budget divided into two five-year blocks to cover the periods 2021-2025 and 2026-2030, with a provisional budget for the five years thereafter.
She told RTÉ's Morning Ireland that the budget is based on the most up-to-date science.
She said: "We have a very real challenge and that [from the Climate Change Act adopted in July] Ireland has set a very high ambition of achieving net zero emissions by 2050 and a 51% reduction by 2030."
In order to get there, she said, the council will put forward an all-economy budget that will be allocated across individual sectors by Government.
Ms Donnelly said that in reducing emissions the electricity sector must shift to renewable energy using wind, wave, water and solar; followed by offshore wind and floating offshore wind in the years to come.
"Ireland is very fortunate in that we have a very high natural resource that will allow us to transition into a decarbonised electricity system over the next years," she said.
Ms Donnelly said that the challenge for each sector will be dealt with in the Climate Action Plan - an annual plan which will come from Government that sets out policies, actions, supports and incentives in place to support each sector to stay within own budget.
The Climate Change Advisory Council will review the performance of each sector on an annual basis.
