The Environment Minister Eamon Ryan says 'every country' should follow Ireland in cutting its emission targets.
Ireland's Climate Change Advisory Council has outlined proposals for a 51% reduction in emissions by 2030, and to achieve net-zero carbon by 2050.
Reports suggest the agriculture sector will have to cut its emissions by 21%, and the electricity sector by 80% by 2030.
It comes as world leaders meet in Scotland for the 2021 United Nations Climate Change Conference, COP26.
Hopes are high that global agreement can be reached to reduce greenhouse gas emissions in order prevent the earth from over-heating.
Taoiseach Micheál Martin will outline Irish plans when he addresses delegates on Tuesday.
Minister Ryan told Newstalk Breakfast Ireland is a good model to follow.
"Every country now needs to do what Ireland is committing to do, which is to half our emissions in a decade.
"That's beyond compare challenging.
"If there's a make or break, if we're saying 'This is the key moment in our time'... this is over the next numbers of years, and it's how we deliver change here at home".
He says the Climate Action Plan is expected to be agreed at Cabinet this week.
"I think we can, in an international arena now, start to stand up and say 'Ireland isn't a bad example here - we have some things happening here that give good news story [sic] and give people hope'.
"The climate plan that hopefully we'll agree on Thursday it builds on the one that Richard Bruton introduced on 2019, and that in turn built on the work that the Joint Oireachtas Committee did across all-parties, all agreeing on some of the big targets around developing renewable power and retrofitting our homes and so on."
He says there has been cross-party agreement before on such issues, on the back of the Citizens' Assembly.
"The benefit of that is we were able to get all-party agreement to stop fracking of gas in Ireland, we were able to get all-party agreement to divest the State's investment fund from fossil fuel investment.
"We were able to get all-party agreement to say 'No we won't do anymore oil and gas exploration, we won't issue new licences'".
On reducing agriculture emissions, Minister Ryan says this will take longer.
"If we're going to change that system, we will not do it just by pointing the finger at people, blaming people, making people feel bad about it.
"We need to create a better system".
But he says a key issue is to protect the Irish family farm model.
"Agriculture will take longer - but we can and will deliver a better agricultural system as we change it.
"The national herd will be smaller and the key metric is can we protect the Irish family farm model?"
Minister Ryan says the current model "is not serving Irish farmers and certainly not the Irish family farm".
He adds that a deposit return scheme for plastic bottles and aluminum cans will be in place as early as next year, and 160 electric buses are on order to come into service in 2022.
