The Finance Minister has admitted some measures in the Climate Action Plan will be 'an inconvenience' to people.
Michael McGrath was speaking as Cabinet prepares to discuss the proposals later on Wednesday.
It will see fewer on-street parking spaces, and measures aimed at cutting the number of car journeys by one-fifth by 2030.
It will also outline how emissions related to agriculture and the construction of buildings will be reduced.
Minister McGrath told Newstalk Breakfast this is not going to be easy.
"There will be measures that will inconvenience people, and we are asking people to change the mindset," he said.
"It's not going to be easy - but having said that, I do think that black and white rules are something that we should avoid.
"There will be circumstances where a parking space is required and is appropriate.
"There'll be circumstances where there isn't fit for purpose public transport services, for example, so all this has to be taken into account."
No 'carve outs for politicians'
Asked about car parking for TDs and Senators, he said: "That really is for the Houses of the Oireachtas Commission to make a call on.
"Many of them will represent different parts of the country, where it may not be as easy as it is from other locations to get to and from Dublin.
"I'm not going to lay down diktats to colleagues who are in very different circumstances.
"Certainly, whatever rules we decide upon and whatever policies are arrived at, there shouldn't be carve outs for politicians that don't apply to others - I think that's the important principle here."
'Short and shallow' downturn
He said that, while the Irish labour market is "particularly resilient", the country will still face economic uncertainty.
"We are certainly not immune from the global economic downturn - and many of our main trading partners are now experiencing much more difficult economic conditions.
"That will have an impact on businesses in Ireland that export goods and services to those countries.
"We are predicting that, across next year, the Irish economy will continue to grow but at a much more modest level.
"Our measure of the domestic economy is modified domestic demand - we believe it'll grow by a little over 1% across next year.
Any downturn, in our view, will be short and shallow - but there is uncertainty, there are risks, there are no guarantees.
"Much depends on what happens, of course, in that terrible war in Ukraine.
"Inflation - we believe we are at or close to the peak, but it will remain elevated across next year.
"We know that monetary policy is going to continue to evolve; the ECB were very clear on that... that interest rates will continue to rise.
"That will act as a further drag on some consumers and some businesses.
"There are risks and challenges, but overall, the Irish economy is resilient," he added.
