CANBERRA, AAP – Barnaby Joyce is sympathetic to Resources Minister Keith Pitt’s call for the federal government to become a financier of last resort for mining.

The Nationals remain locked in negotiations with the Liberals for a target of net zero emissions by 2050 weeks out from the Glasgow climate summit.

Resources Minister Keith Pitt has called for the government to create a funder of last resort for mining projects that can’t otherwise get financing.

Senator Matt Canavan remains adamant in his opposition to net zero.

“I have sympathy for what they say because I don’t like the idea that our sovereignty of our nation is determined by a financing arm of another country or a board member,” Mr Joyce told ABC radio on Thursday.

The Australian Financial Review reported Mr Pitt has called for a $250 billion loan facility in exchange for the Nationals’ support for a net zero target.

Meanwhile, independent MP Zali Steggall will reintroduce her climate change bill to parliament when it returns from October 18.

She wants to see a 60 per cent emissions reduction on 2005 levels by 2030 and for the responsible minister to have a positive duty to ensure climate adaptation goals are in place.

“The business sector, the private sector, industry, unions, medical associations, planners all have said loud and clear that the climate change bills are the policy framework we need to offer certainty and stability for investment,” she told ABC TV.

“We’re on the eve of the Olympics of international policy, COP26. History will remember the leaders who show up and show up with a plan to win a gold medal.”

Prime Minister Scott Morrison has indicated he is unlikely to attend the United Nations talks but no final decision has been announced.

He maintains Australia will be represented at a senior ministerial level.
