Anthony Albanese warned the Greens and the bench, warning that he would not give in to pressure to increase his climate targets.
The prime minister will introduce a bill next week that sets a target of 43% emission reductions by 2030 and zero by 2050.
The government’s approach has been criticized by the cross-bench, which accused it of taking a “my way or my best” approach to legislation.
Speaking on ABC radio Thursday, Mr. Albanese changed the Greens’ mind by insisting they were playing hard.
“The Greens basically spoke in public, not what they told us,” he said.
We are happy to consider any reasonable amendments that may improve the legislation.
“But what we’re not happy to do, to be very clear, is to change the issue for which we have a mandate.”
Energy and Climate Change Secretary Chris Bowen briefed the panel of judges and the Greens on the law last week.
While the government does not need to legislate goals, it does want them to be fixed to give business certainty.
The bill is due in the House of Representatives on Wednesday or Thursday next week.
After it passes through the lower house, which the government hopes will happen in the next two weeks, it will be sent to a Senate committee and taken to the upper house when Parliament returns in September.
With just 26 votes on the Senate floor, the government needs to defeat the Greens and the cross-bench after opposition leader Peter Dutton ruled out support for the Coalition.
But the Greens want the bill to work as a minimum, not a ceiling, and have raised concerns about enforcement mechanisms.
Leader Adam Bandt said he wants the bill to be “endorsed by Dutton” so that the future government cannot lower the targets at a later date.
“We will negotiate in good faith with the government, and we hope that the government will give up its insistence on a weak target and open up more coal and gas,” he said.
But Mr. Albanese said he wouldn’t care.
“I saw a film in which the government says one thing before the elections, and then another after. And I know how it ends. It ends badly,” he said.
