Federal Liberal MPs say the tide is turning against their Nationals colleagues opposed to Scott Morrison's plan for a new roadmap to reduce emissions.
Tensions have been high in government ranks over an internal push to commit Australia to net-zero emissions by 2050, with the Nationals hitting out at the proposal and saying it would hurt people in regional and rural areas.
However, moderate Liberals are backing the plan and North Sydney MP Trent Zimmerman says the climate measures will benefit the regions.
"Right now, (the Nationals) are focused on what the economic transition would be, but the tide is shifting," he told ABC radio on Tuesday.
"It will be a driver of new jobs and industries and this is the silver lining of the climate change cloud."
Mr Zimmerman also said the prime minister had yet to make a decision on whether to attend in person a major global climate conference in Glasgow in November.
A survey of government backbenchers has found 12 - including Mr Zimmerman, Liberal senator Jim Molan, and former Nationals leader Michael McCormack - support a net-zero emissions target.
But the majority of backbenchers have yet to commit, the survey published by The Australian found.
Opposition Leader Anthony Albanese said regional areas would be among the hardest hit locations if an emissions target was not created, due to more frequent natural disasters.
"The Nationals have been taken over by conspiracy theorists, accountants and bankers who like to play dress-up, but what we need is a serious policy going forward," he said.
"Action on climate change is good for jobs and the economy and the environment.
"What people in regional areas have to fear is inaction on climate change."
The Nationals are next due to meet as a party room when parliament resumes in mid-October.
Vocal members of the Nationals have hit out at any potential net-zero plan, with Queensland senator Matt Canavan indicating there would be no way he would support any measure.
"This is too great a cost for our country to bear," he said.
"The UN said if you go to net-zero, you would have to end (the coal industry) by 2030, and it's not something I can contemplate."
Meanwhile, Nationals senator and minister Bridget McKenzie said it was easy for urban Liberals like Treasurer Josh Frydenberg to push for the target because the impact on their "affluent constituents" would be minimal.
"Our people, by contrast, are generally living in the electorates with the lowest per capita incomes, while the industries that underpin our regional economies are emission-intensive," she wrote in an opinion piece published in the Australian Financial Review on Tuesday.
