The Dáil has backed a motion declaring a climate and biodiversity emergency.
The Fianna Fáil motion passed today without a vote after being accepted by government and opposition parties.
It's become only the second parliament to back such a move.
Despite government agreement, the motion isn't legally binding.
Green Party leader Eamon Ryan said he's glad the Dáil supported calls for an emergency.
“Ireland has become a climate laggard in the last eight years but there is no reason we could not turn that around and become leaders.
"We need to change our entire food, energy, transport and industrial systems in the next two decades and deliver a just transition through a Green New Deal."
Addressing the Dáil, Climate Action Minister Richard Bruton said he hopes this is the start of an important process.
He suggested politicians will have to find a way to work through their 'ideological differences' to achieve change.
