"We plan to host the 31st Conference of the Parties to the United Nations Framework Convention on Climate Change in Turkey next November," Erdogan told leaders at the G20 summit in Johannesburg, referring to COP31.

Under an unusual compromise agreement laid out in a document seen by AFP, Turkey will host the two-week summit in the southern resort city of Antalya and retain the formal COP31 presidency, while Australia would serve as vice president and chair the negotiations.

Erdogan's remarks came after the two countries finalised a deal following a long-running standoff over the event.

"I believe the consensus we established together with Australia is of high importance," Erdogan said.

Both countries sought to host COP31 in November 2026 and neither would back down, sparking a bidding war rarely seen for the annual climate talks.

Australia enjoyed greater support than Turkey but the deadlock prevented a host from being chosen by consensus as required under United Nations rules.

The "pre-COP" -- technical consultations that usually occur about a month before the main summit -- are to take place in a Pacific Island nation, in a nod to Australia's original intention to co-host with its neighbours.
