The Green Party is entering Government formation talks with Fine Gael and Fianna Fail.
The leader Eamon Ryan will now request a meeting with the two larger parties.
The Taoiseach had said earlier this week that he was keen to discuss the possibility of forming a Government along with the Green Party, however there were some issues surrounding how a seven percent reduction in greenhouse emissions.
The Green Party say they have got approval from the parliamentary party on developing a programme for government.
In a statement, it says that it will require the support of two-thirds of all of its members.
No legislation can now pass, until a Government is formed, with Fine Gael and Fianna Fail needing the support of independents and another party.
The Fianna Fáil Leader has welcomed the confirmation that the Green Party will now enter into formal negotiations.
Micheál Martin says as the country faces into a very uncertain future, it is critically important we have a solid and stable Government in place.
He says he wants the parties to protect people and ensure the country's economic recovery after Covid-19 is started as soon as possible and is built on fairness.
He says there's important legislation that needs to be passed to allow Irish businesses to access finance and there needs to be a government in place to do this.
