Uncertainty persists over how COP31 will be managed, after Türkiye's environment minister told journalists this week his country will have the final say at the UN climate conference despite a deal that gave Australia the role of chairing the negotiations in return for withdrawing its bid for the summit.At COP30, the two governments resolved a deadlock by agreeing that Türkiye would host this year's annual talks in the resort city of Antalya with its environment minister Murat Kurum serving as COP31 President, while his Australian counterpart Chris Bowen would act as COP31 President of Negotiations.Previous COPs have occasionally been hosted by one country and presided over by another. For example, COP23 was held in Germany because of the remoteness and small size of Fiji, and COP25 took place in Spain after social unrest flared in Chile. But COP31 will be the first UN climate summit with the powers of the presidency split between two countries.
