Anthony Albanese has flagged a complete overhaul of the party’s climate change policies, including the likely scrapping of Bill Shorten’s 45 per cent emissions-reduction target by 2030.

On Sunday, the Labor leader confirmed the new focus on a longer-range target of achieving net-zero emissions by 2050.

Mr Albanese said it was time to overhaul the policies, given the 45 per cent reduction timetable was predicated on winning the 2019 election.

“That was a commitment that was given in 2015. So that was a commitment in about 15 years’ time,” he said. “So, we’ll examine our short-, medium- and long-term commitments in terms of where we go on climate change, but we won’t be re-examining our principles.

“We need strong action on climate change. We want to work towards zero emissions by the middle of this century.”

Mr Albanese said Labor’s commitment to climate-change action remained unchanged and was not being diluted.

“But by definition, when you aren’t successful after the 2015 targets, the 15-year target ahead, by definition that changes. But our resolve on climate change is very clear, just like our resolve on supporting renewable energy, clean energy.”

The Labor leader flagged a series of “vision statements” over the next six months outlining a new policy agenda beginning with jobs, the future of work and the economy.

Mr Albanese said he agreed with Labor MP Joel Fitzgibbon’s call to meet international obligations on climate change without harming the economy.

“Well, obviously we should meet our international obligations, and obviously we want a strong economy. The difference between Labor and the government is that there is no debate within the Labor Party about whether climate change is real, about the science,” he said.

And there’s no debate over whether we need strong action. We support the science. The science tells us that we need to act.’’

Labor’s climate change spokesman Mark Butler said any new emissions-reduction target would still be higher than Australia’s Paris Agreement targets of reducing emissions by 26 to 28 per cent.

“It’s clear 26 to 28 per cent is fundamentally inconsistent with the obligation to keep global warming way below 2 degrees [Celsius],” Mr Butler told ABC’s Insiders.

“What I have said is all our policies are up for review, exactly what medium-term targets numerically are, whether it’s 2030 or 2035, given the passage of time, is something we’ll engage over in the next couple of years.

“People can be assured it would be a medium-term target utterly consistent with the best scientific advice about how we meet those commitments in the Paris Agreement and keep global warming well below 2 degrees [Celsius] and pursue efforts around 1.5 [degrees Celsius].

“That is our generation’s responsibility to our children and our grandchildren.”
