Another federal Labor frontbencher has called for the party to drop the carbon emissions reduction target it took to the May election.
Matt Keogh told The Australian on Thursday he backs Labor resources spokesman Joel Fitzgibbon's call to bring the party's target to a 28 per cent reduction of 2005 levels by 2030.
Labor went to the May poll with a 45 per cent reduction target over the same period, while the coalition flagged a 26 to 28 per cent reduction.
Mr Fitzgibbon used a speech at the Sydney Institute on Wednesday to call for the reduced targets, saying by matching the coalition, the government would then have to act.
"Joel is also right in saying that, if that agreement is government policy, it is the government that is responsible for that," Mr Keogh told the Australian.
Labor Queensland senator Anthony Chisholm told the Australian the party couldn't leave itself vulnerable to scare campaigns from the government.
Labor frontbencher and Queensland MP Shayne Neumann told the broadsheet Mr Fitzgibbon's speech was "important" and "unless you are seen to be supporting the mining industry you can't win seats in Queensland".
But Labor's climate change spokesman Mark Butler has said matching the government's smaller targets would breach Australia's Paris climate change agreements.
Mr Butler said the government's targets were set by former prime minister Tony Abbott and if adopted worldwide would lead to global warming of three degrees.
Labor leader Anthony Albanese weighed in, tweeting strong action climate change would "not only protect our environment but is also good for our economy".
Energy Minister Angus Taylor jumped in on the split on Wednesday, saying Labor was in "chaos".
