Australia must stop subsidising new fossil fuel developments if it is to win a key Pacific nation’s support for its plan to co-host a major UN climate summit in 2026.

The Albanese government has launched a campaign at the Cop27 climate talks in Egypt to co-host the annual climate conference with Pacific neighbours in four years. The proposal could bring tens of thousands of people to an Australian city for climate negotiations and advocacy and has won support from the Pacific Islands Forum.

Vanuatu’s new climate change minister, Ralph Regenvanu, told Guardian Australia the support should be conditional.

A former foreign affairs minister who took on responsibility for climate change after national elections last month, Regenvanu said he was not critical of the Albanese government, describing it as a “breath of fresh air” and a refreshing change after the Morrison government, which was widely criticised for its inaction on global heating.

But he said his government could not endorse Australia’s co-hosting bid if it invested more money in developing fossil fuels, and would call on other Pacific countries to adopt the same stance.

"I will be talking to other Pacific Island nations to make our support for Australia hosting the Cop conditional on no new government money being given to fossil fuels,” he said.

Regenvanu also called on Australia to rejoin the Green Climate Fund, which finances climate and clean energy projects in developing countries. Scott Morrison abruptly withdrew Australia from the fund in 2019, arguing his government would instead pay climate funding directly to Pacific countries.

Some Pacific countries have indicated they prefer this model as they believe the Green Climate Fund has not not focused enough on clean developments in the region. The Albanese government has not yet declared its position on the global fund, but announced an additional $900m to support climate development and resilience in the Pacific in the October budget.

Regenvanu said Australia should rejoin the fund to help fix it. “I told the minister that they need to get into the Green Climate Fund and change it so the most vulnerable countries, including in the Pacific, have access,” he said.

The climate change minister, Chris Bowen, has said there would be no government finance for new coal and gas fields under Labor, and some funding for gas and carbon capture and storage developments announced under the Coalition was redirected in the budget.

But the government has been criticized for maintaining $1.5bn equity support announced by the Morrison government for Darwin Harbour’s middle arm industrial precinct, which is expected to include developments using gas, and for expanding the offshore area available for oil and gas exploration.

Phasing out fossil fuel subsidies is a major focus for some countries at Cop27, with Tuvalu joining Vanuatu in calling for a fossil fuel non-proliferation treaty.
