Australia’s bid to host COP31 in 2026, with Adelaide leading in partnership with Pacific island nations, now faces a major challenge. Turkey remains committed to securing full hosting control, setting the stage for a diplomatic showdown just days before a final decision is due. With an estimated 50,000 attendees and billions of dollars in economic impact at stake, both sides appear unwilling to compromise.
Australia has suggested a shared approach, with Adelaide hosting the main sessions and Turkey leading a forum for world leaders. Ankara has rejected the arrangement, maintaining its position for exclusive hosting rights. This response was delivered in a letter to the Australian Government, reigniting discussions that have been ongoing since September. In response, Australia has contacted Pacific allies to reaffirm their support.
Hosting the summit could deliver significant exposure and financial benefits to Adelaide, with government estimates predicting costs of up to $2 billion. However, some members of the Australian cabinet are beginning to question whether the potential influence and prestige are worth the financial cost and political complexities. Turkey, for its part, remains firm, refusing to consider joint hosting despite continued diplomatic efforts by Australia.
This dispute may shape the way future global climate summits are organised, particularly where national interests clash with broader environmental goals. Australia’s strength comes from the backing of Pacific island countries that view the summit as a vital opportunity to highlight their climate challenges. Still, the outcome remains uncertain and with only days remaining, the international community is watching closely to see whether either side will shift position or whether external diplomacy will decide the issue.
