What happened at the COP29 talks?

The petroleum-laden dust has settled on this year's United Nations climate summit, COP29, held over the past fortnight in Baku, Azerbaijan.

Climate scientists, leaders, lobbyists and delegates are heading for home. The meeting achieved incremental progress.

Negotiators agreed on a new climate finance target of at least $300 billion a year by 2035 (A$460 billion), up from $100 billion now. These funds would help developing nations shift away from fossil fuels, adapt to the warming climate and respond to loss and damage from climate disasters.

Nations also agreed on the essential rules for a global carbon trading market, the last agreement needed to make the 2015 Paris Agreement fully operational. As UN climate chief Simon Stiell said in the final session, the 29th Conference of the Parties (COP29) meeting showed the Paris Agreement was delivering on climate action, but national governments "still need to pick up the pace".
