who started school after the first covid lockdown. researchers in the uk say blood that has been grown in a laboratory has been put into people, in a world first clinical trial. it could help scientists manufacture rare blood groups. the head of the united nations has warned the cop27 climate conference in egypt that nations must co operate in the effort to reduce global emissions or perish. antonio guterres decribed the progress made since last year s gathering in glasgow as woeful. the prime minister, rishi sunak, is expected to warn world leaders later that it s essential that countries stick to the commitments made then to limit global warming to 1.5 degrees celsius above pre industrial levels. our climate editorjustin rowlatt reports from the conference. the world leaders swept into the conference centre in the egyptian desert this morning. among them the british prime minister, rishi sunak. there was a formal handshake with the un chief, all 120 world leaders at the
as generous government subsidies end and electricity prices surge, sales of evs are slowing around the world. so what can governments and carmakers do to recharge consumers interest? i m going to be discussing all of that with these three. there they are, the boss of the organisation working to make charging evs easier. a global ev battery expert and the state secretary for the norwegian ministry of transport, who explains just how norway has become a super player in the electric vehicle market. also on the show, one carmaker showing no signs of a lack of confidence in evs. the boss of general motors europe explains why it s committed to an all electric range. wherever you rejoining me from around the world, once again, a big hello and a warm welcome to the show. well, as i said, love them or hate them, or even if you re simply not sure, but one day we re all going to be plugging in, switching on and driving electric vehicles. that s the plan. it s part of a strategy by gove
emissions and limit global warming. they ve been offering generous subsidies to encourage drivers to make the switch to, well, more environmentally friendly electric cars. so far, they ve worked, tempting new ev drivers to overlook less desirable factors like battery range, the higher price tag and a charging infrastructure that s still in its infancy and racing to catch up with demand. sales of electric passenger cars currently make up 14% of the total global car sales and have been doubling roughly every year. that s according to the iea, the international energy agency. but after a heady few years of booming sales, recent numbers show that the trend, while it s still growing, is slowing. the reason? well, rising costs in electricity in some countries have made running ev cars more expensive than driving on petrol or diesel. at the same time, those government subsidies, they re coming to an end. but prices of evs, they are staying high and that, according to the experts, is
We see is that by 2035, you re going to need over 300 new mines to meet projections by 2035 or seem to lithium demand is going to double and these minerals and these huge demands show to me, production from the batteries but again, the big difference with fossil fuels that are burned off as we can recycle these minerals we use them in batteries. 0nce recycle these minerals we use them in batteries. once you produce these batteries, they can be recycled in those materials we use, that will help cut down the carbon footprint. henry, at what point does driving an ev pay off, where the savings on carbon emissions outweigh the emissions created in making the car and the batteries? studies show that, you know, as soon as less than two years of driving, you can pay back the carbon debt, if you like, or the carbon emissions caused by manufacturing the battery. but the critical thing is the supply chain, the battery manufacturing is moving to areas of
Down? it is enormous. you are replacing down? it is enormous. you are replacing potentially down? it is enormous. you are replacing potentially 2 - down? it is enormous. you are replacing potentially 2 billion l replacing potentially 2 billion vehicles on the road so what we will see is by 2035, you are going to need 300 new mines of the projected demand by then and we are seeing lithium demand double as well as nickel, cobalt so there is huge demand by the end of the decade to meet production of new batteries but eventually the big difference with fossil fuels is that we can recycle minerals and we use them in batteries. 0nce minerals and we use them in batteries. once we produce all these batteries, they can be recycled in those materials reused so that will help cut down the carbon footprint. henry, at what point does driving an ev pay off, where the savings on carbon emissions outweigh the emissions created in making the car and the batteries? studies show that, you know, as so
