Cop28 president and oil chief says phase-down and phase-out of fossil fuels is essential and says his comments were misrepresented

• Cop28 president says there is ‘no science’ behind demands for phase-out of fossil fuels

John Kerry, the US special envoy for climate was just asked on the BBC Radio 4 Today programme in the UK what he thinks of Damian Carrington’s scoop that Sultan Al Jaber said there was ‘no science’ behind demands for phase-out of fossil fuels.

He was very diplomatic in his response and appeared to give the oil chief and Cop28 president the benefit of the doubt.

“What you have to do is clearly reduce the emissions. They have made it clear we need a 43% minimum reduction in emissions by 2030, and we need net zero 2050 in order to meet the goal of keeping 1.5. We’ve got all kinds of ways of getting there. Renewables are the one technology we really know we can deploy today and it has the impact we need.”

“We are not only signed up to that, president Biden on behalf of the US voted to join the g7 where we said we must phase out unabated fossil fuel. We have to do that yes otherwise you cannot reach net zero by 2050. What we are trying to figure out is how we can capture those emissions, or reduce those emissions, or not make those emissions in the first place.

“I think the only question here is not whether or not you are going to reduce emissions, it’s what means are you going to use to go at this to provide the energy you want for your country but also keeping faith with the reduction of the emissions that are creating the climate crisis.”

• Cop28 president says there is ‘no science’ behind demands for phase-out of fossil fuels

The British prime minister, Rishi Sunak, has been facing criticism at home for the brevity of his visit to the climate conference, having visited for less than a day. He has also been accused of hypocrisy for pushing for a phase-out of fossil fuels only weeks after approving new oil and gas licences in the North Sea.

Al Gore, the former US vice-president, said: “I am not impressed with prime minister Sunak’s climate policies. I think they’re terrible. They’re very disappointing.”
