Minister for the Environment Eamon Ryan will have to interrupt his attendance at the COP28 Climate Summit in Dubai to return to Ireland for the confidence vote in Minister for Justice Helen McEntee.
Mr Ryan will then travel back to the event in the United Arab Emirates after the vote on Ms McEntee takes place in the Dáil on Tuesday.
Sinn Féin tabled a motion of no-confidence in Minister McEntee following the Dublin riots.
The Government is confident of winning the vote.
Speaking at COP28 today, the Taoiseach Leo Varadkar described the situation as unfortunate and "not ideal."
"There are no pairs for confidence motions other than for illness, so as a result of that, Minister Ryan will have to go home and come back again," Mr Varadkar said.
The moves means the Green Party leader's carbon footprint from travelling to the summit will be doubled.
However, Mr Varadkar said "of course he will offset the emissions, we have a mechanism for doing that".
Mr Varadkar said the Government would "much rather if it weren’t necessary," but he said the motion was put down by Sinn Féin.
He believes Sinn Féin and the Social Democrats "have got it wrong" in relation to the motion of no confidence in Ms McEntee.
Mr Varadkar accused the parties of "making a mistake by bringing this divisive motion" to the Dáil next week.
Speaking at COP28 today, he insisted the motion of no-confidence "can only fail."
Mr Varadkar said the country was "shocked and traumatised by what happened last Thursday in Dublin".
The Taoiseach said he believes "most people in the country wants politicians to work together" to address the matter.
Minister for Justice Helen McEntee has said she wants to reassure people that Dublin city is safe and she said she has been working closely with the Garda Commissioner Drew Harris and the Gardaí to make sure people have confidence to come into the city centre.
Asked whether she had taken a political hit over her handling of the aftermath of the riots, Ms McEntee said she was absolutely focussed on making sure Dublin city is safe and she said it was important to make sure people feel safe and that they know that those responsible will be brought to justice.
Ms McEntee said there would be a new garda operation announced in the coming week to combat retail theft.
Poll suggests public support McEntee to continue as Justice Minister
More than half the respondents in a new poll have said that Justice Minister Helen McEntee should not resign over her handling of the aftermath of the riots in Dublin.
54% said she should not step down in a new survey from the Sunday Independent newspaper and Ireland Thinks while 40% said she should resign.
Ahead of a Dáil vote on a Sinn Féin no confidence motion in the Minister, the poll found 38% are satisfied with her performance as justice minister, up 9% on a comparable survey last August.
However, 49% are not satisfied with her handling of the Justice Department.
Half of those polled also believe Garda Commissioner Drew Harris should not resign in the wake of the riots while 41 per cent believe he should.
Support for Sinn Féin is down three points to 28% since the previous poll in November.
Fine Gael is unchanged at 21% while Fianna Fáil is up one point to 19%.
The Social Democrats are unchanged at 5%.
Labour is up one point to 4% while People Before Profit is unchanged at 4%.
The Green Party has dropped one point to 3% while support for Aontú is unchanged at 3%.
Independents and others are up 3 points to 14%.
The poll was taken on Friday and Saturday of this week among a sample size of 1,306 with a margin of error of plus or minus 2.8%.
