US envoy Kerry launches international nuclear fusion plan at COP28
The elephant in the expo centre: Who's hosting COP29?
There's an unprecedented deadlock at this year's COP28 U.N. climate summit over who will host next year's event.
The conference's opening days saw scant reference to COP29, unlike in previous years, when speakers usually namecheck the next COP presidency to show that the world's climate fighting strategy is mapped out for years to come.
By this stage, the next host is normally planning the summit and laying the diplomatic groundwork for their presidency.
Under U.N. rules, it is the turn of eastern Europe to host a COP, and the decision must be unanimous by all countries in the region. The Ukraine war, however, has made that all but impossible.
Russia, which is being sanctioned by the European Union for invading Ukraine, has opposed holding COP29 in an EU member state and is blocking Bulgaria's bid.
The other two potential hosts, long-term adversaries Armenia and Azerbaijan, are ruled out because they refuse to back each other.
