The world leaders’ summit is over, and the negotiators take centre stage. Sunday’s official themes are health, relief, recovery and peace

Good morning! This is Alan Evans, bringing you coverage from the fourth day of the UN’s Cop28 climate summit.

The Guardian will be liveblogging the negotiations throughout. You can email me on alan.evans@theguardian.com or on X/Twitter at @itsalanevans, and my colleague Jonathan Watts (jonathan.watts@theguardian.com) will take over later on.

Colombia, a major fossil fuel producer, has formally joined an alliance of nations calling for a fossil fuel non-proliferation treaty to prevent the “omnicide of planet Earth”.

The US was one of several countries to join an alliance to phase out power plants that burn coal and announced rules to cut its methane emissions.

At least 117 governments agreed to triple the world’s capacity of renewable energy by 2030 and double the rate of energy efficiency improvements.

Fifty oil and gas companies signed a “decarbonisation charter” that analysts have criticised for ignoring the emissions spewed when customers burn the fuels.

Twenty-two countries have pledged to triple nuclear capacity by 2050.
