There must be action on tackling climate change across all sectors of society, a member of the Climate Change Advisory Council has said.
However, Professor Peter Thorne indicated that the Government's updated Climate Action Plan may fall short on the allocated emissions reduction that is required to meet carbon budgets, and stated "it is no clearer where that is going to fall".
"That is key because we need clarity for businesses, for sectors, for citizens as to what will need to be done to fully meet the reductions that are mandated," he said.
Measures announced in the plan include:
-Enough renewable electricity to power every home and business in the country by 2030
-70% of people in rural Ireland to have buses that go three times a day to the nearest town
-500,000 homes retrofitted to BER B2 to make them warmer
-One in three private cars on our roads to be electric by 2030
-Walking, cycling and public transport to account for 50% of all daily trips
-Tillage farming to cover up to 400,000 hectares by 2030
The plan also includes a climate action roadmap for every sector of the economy consistent with the legally binding target of a 51% reduction in greenhouse gas emissions by 2030.
Speaking on RTÉ's Morning Ireland, Prof Thorne said Ireland is very reliant on cars and it can be done differently by looking at other locations such as Copenhagen and Amsterdam where there has been a successful "change by design".
He said every aspect of the Climate Action Plan is possible to achieve even if they are "technically challenging".
Sinn Féin's spokesperson on Climate Action and Transport said the Government is "consistently" missing its climate action targets.
Speaking on the same programme, Darren O'Rourke said Minister Eamon Ryan has failed to deliver the capacity within the planning system and added that Sinn Féin would focus on resourcing the planning system.
He said they would introduce a tiered support for solar PV and invest in connecting the rural transport plan "to fast track it".
He said communities need to see "rural transport services before any talk of levies".
Mr O'Rourke also said there is deep, deep concern within the energy sector that the planning sector will not be sufficiently resourced.
Minister for Agriculture Charlie McConalogue said farmers do not get the "due recognition and respect" for the work they are doing to reduce their emissions while continuing to produce food.
He said Government is laying out a clear plan regarding how they will work with the farming sector and family farms to reach climate action targets.
The farming sector is the first that had a plan in place regarding targets, he said.
"I have been very clear in relation to the options we are providing farmers, how we have worked with farmers already and how we are offering new options in the decade ahead which will improve farm incomes and help reach that 25% target," he said.
For example, he said, if a farmer has 100 acres of land and 100 cows, and he decides to incorporate 20 acres into forestry it will improve profitability, lower emissions and improve sequestration.
