Australia Rejects Turkey’s Co-Hosting Proposal as COP31 Standoff Deepens

Australia has firmly ruled out co-hosting next year’s COP31 climate summit with Turkey, escalating a two-year diplomatic standoff that threatens to derail both countries’ bids. Prime Minister Anthony Albanese said on Monday that joint hosting is “not an option” under UNFCCC rules, pushing back against Ankara’s proposal for a shared presidency. Turkey revealed over the weekend that it had proposed a joint model in which Australia would host a leaders’ gathering focused on Pacific island nations before Turkey stages the main COP31 negotiations. But Albanese dismissed the concept entirely, saying the framework simply does not exist within U.N. rules. “People are aware that it is not an option,” he told reporters in Melbourne. The deadlock now casts serious uncertainty over next year’s summit, with the final decision expected at COP30 in Belém, Brazil. Australia and Turkey both submitted bids in 2022 and have refused to withdraw. Letters exchanged in recent weeks between Albanese and Turkish President Tayyip Erdogan have only hardened positions rather than bridged differences. Under UN guidelines, the 28-member “Western Europe and Others Group”—which includes both contenders—must reach unanimous agreement on the host. Without compromise, COP31 would automatically default to Bonn, Germany, though German officials have repeatedly said they do not wish to take on the role. Turkey maintains it is open to compromise on a joint arrangement, but also insists it is prepared to stand by its solo bid. Turkish diplomatic sources say Erdogan wrote to Albanese on Nov. 10 urging flexibility while reiterating Ankara’s readiness to host the main summit. Turkey argues that a COP under its stewardship would spotlight climate-finance needs for developing nations and highlight its progress toward a 2053 net-zero goal. Australia, meanwhile, is campaigning to host the summit with Pacific island nations for the first time. The 18-member Pacific Islands Forum has strongly endorsed Canberra’s bid, viewing it as crucial to amplifying the existential threats facing the region, particularly sea-level rise. At COP30 on Monday, Norway publicly backed Australia’s pitch, echoing the importance of elevating Pacific voices. Australia’s Climate Change Minister Chris Bowen arrived in Belém on Sunday to intensify lobbying efforts. His presence, observers say, has boosted Australia’s visibility at a critical juncture. Thom Woodroofe of the Smart Energy Council noted that the two countries’ priorities for COP31 differ significantly, making a joint presidency difficult—but suggested Australia may still need to find a way to “accommodate Turkey’s desire to lead” to avoid a collapse in negotiations. As talks continue in Brazil, the stalemate threatens to overshadow broader climate diplomacy. With the host role shaping the summit’s agenda, political tone and global investment flows, the failure to reach agreement would be a major setback for both Australia’s Pacific ambitions and Turkey’s emerging climate leadership.
