Deputy Prime Minister Barnaby Joyce says Australia will stick to international agreements for action on climate change, no matter if the US pulls out.
The Turnbull government is likely to resist pressure from within its ranks to dump the renewable energy target and pull out of the Paris climate change agreement, even if the US does.
Deputy Prime Minister Barnaby Joyce says Australia is known as an honourable negotiator that sticks to agreements it makes.
"We are not the United States of Australia, we are just Australia. The United States will look after their business and we'll look after ours," he told ABC radio on Monday.
Former prime minister Tony Abbott has called on the government to dump its renewable energy target, which he cut when in office.
And a growing number of coalition MPs want Australia to follow new US president Donald Trump's lead and pull out of the Paris climate agreement, The Australian reports on Monday.
Mr Joyce said people in the government "have the benefit of free will, they think what they wish" and backbenchers were free to express those views.
Nevertheless, he indicated Australia would be sticking with the climate plan.
"We don't sign agreements to pull out of them," he said.
"We go into them, we negotiate with the belief that if you sign a piece of paper you should be sticking to it."
Energy Minister Josh Frydenberg has said the government has no plans to change the renewable energy target.
