Labor rules out governing with the Greens

"We can put the climate wars behind us," he promised.

Just hours earlier, deputy Labor leader Richard Marles ruled out doing a deal with the Greens to form government should the upcoming election fail to produce a clear majority for either of the big parties.

Prime Minister Scott Morrison dragged up the possibility of a Labor-Greens coalition after the opposition released its long-awaited climate change policy last week.

Labor aims to reduce emissions by 43 per cent by 2030 but Mr Morrison claims this is only for starters as the Greens will want a much higher target in a Labor-Greens coalition.

The Greens have a 2030 target of 75 per cent.

"This is Scott Morrison lying again," Mr Marles told Sky News' Sunday Agenda program.  

"We are seeking government in our own right. We are not going to enter into a coalition with the Greens. We have been making that clear from day one."

Government minister Anne Ruston said Labor would try to play down its relationship with the Greens.

"But they will never have the majority in the Senate, it's just not possible," she told Sky News.

"They will have to get the support from the Greens to get legislation through. I just can't see how they are going to be able to that without doing a deal with the Greens."

Senator Ruston also found it "quite weird' that Mr Albanese said the 45 per cent 2030 target taken to the last election was a mistake, yet 43 per cent was the panacea.

The coalition has a 2030 target of 26 to 28 per cent but expects it will end up being 35 per cent.

Treasurer Josh Frydenberg was asked on ABC's Insiders whether the Business Council, the Australian Industry Group and Liberal state governments had got it wrong in wanting a higher target but he and Nationals Leader Barnaby Joyce had got it right.

"We've got the right plan, we're going to see emissions down by up to 35 per cent by 2030, we're committed to net zero by 2050, this is an important environmental but also economic objective," he said.
