i'm sally bundock. so let's now get down to business and it is the eve of cop 28 in dubai, where world leaders, government representatives and delegates will discuss ways to tackle climate change. this year, health will be at the heart of the summit with the first ever official health program. from the lab to the patient, the healthcare industry is responsible for twice the carbon emissions of the aviation sector. now rival ceos from seven of the biggest pharmaceutical companies, alongside the world health organization are set to decarbonise the sector and make healthcare more sustainable. i spoke to pascal soriot, the ceo of astrazeneca and is heading up the task force and paul hudson, the ceo of sanofi. i began by asking pascal what has already been achieved. each company card to reduce carbon emissions. as a company astrazeneca over the next few years we reduce carbon emissions by 60% even though the size of the company almost doubled. at the top 28 we are planning to announce a joint effort to source green energy in china and in india. in china in china and in india. in china in particular, we have a plan to source energy together that will save the equivalent of about 25,000 cars that will be taken off the road in terms of carbon reduction.— carbon reduction. talk us through _ carbon reduction. talk us through the _ carbon reduction. talk us through the

are you finding this task force and working together is leading to other collaboration in other areas? absolutely, ithink other collaboration in other areas? absolutely, i think the task focused on a lot of good work and we are helping people realise that the healthcare sector is contributing 5% of global carbon emission, up to 8% interplay belt country. we have been delivering across mostly european companies and in other parts of the healthcare sector. we have various things but now we are also collaborating with a role that has been formed in the united states and we have just launched a couple of weeks ago a chinese chapter of the smi in china, where companies are also coming together to reduce carbon emissions across the healthcare sector. so there is a growing realisation across the healthcare sector that we need to do our part, to reduce carbon emissions. as paul said it is a little bit ironic in a way because we are here to help patience but in reality we also contribute to this big health crisis that is the climate change by producing a lot of carbon. ok, thank you both your time. carbon. 0k, thank you both your time. ., ~' ,, , carbon. 0k, thank you both your time. ., ~' , . high on the agenda at cop will be discussions about ways in which countries and businesses can find alternative energy sources. nuclear is one of course and has gained in prominence to help achieve net zero targets since the war in ukraine. the us will lead a push at the cop 28 climate summit to triple the amount of installed nuclear power capacity globally by 2050, marking a major turnaround for the controversial technology at the climate negotiations. and this week, the world nuclear exhibition is under way in paris with more than 17,000 participants expected. carlos torres is senior vice president and head of gas and power markets research at rystad energy , an independent advisory service to the sector. just give us your take on the position of nuclear then in this debate about energy security. this debate about energy security-— this debate about energy securi .�* , , . security. because ever since the fukushima _ security. because ever since the fukushima disaster - security. because ever since | the fukushima disaster there the fu kushima disaster there was the fukushima disaster there was a huge turnaround in thinking about it. we saw countries like germany massively pullout of nuclear, whereas now it is coming back to the fore, isn't it? you make yes exactly. the renewed interest is there because it is a source that provides carbon free electricity and then it gives a lot of energy security for countries that rely on fossil fuels so many countries are exploring like increasing the amount of nuclear capacity in their country. there are also many challenges that the industry needs to face, like social opposition. the technology is more expensive than other sources of electricity and that it is not flexible so it does not match well with renewable energy sources so i think we need to find a balance between the pros and cons of the technology can offer. let's talk about that. where does it sit within the debate about renewable technology. how green is nuclear compared to others? well, it is very green so it provides carbon free electricity supply. it is a very good alternative for countries relying on fossil fuel. china has said that in order to conquer dependency on coal—fired energy they will be using more nuclear generation and this is a good alternative. but it also competing with other sources of carbon free technology, like solar and wind, which are cheaper and that are easier to deploy so that are easier to deploy so thatis that are easier to deploy so that is where nuclear is facing some challenges.— that is where nuclear is facing some challenges. what about the risks? i mentioned _ some challenges. what about the risks? i mentioned the _ risks? i mentioned the fukushima disaster. we all remember that well. they are dealing with it even now, with some countries choosing not to buy their exports from the seas around the area because of fears of contamination. there are risks and that has to be

tackled, doesn't it? yes, there are many risks and there - tackled, doesn't it? yes, there are many risks and there is - tackled, doesn't it? yes, there are many risks and there is a i are many risks and there is a lot of social opposition, especially after fukushima. many countries across europe decided to shut down nuclear reactors because of the social opposition they were facing. so definitely this will be a very big hurdle that will be probably stopping a lot of possible pilots because many people wanted in their —— not many people wanted in the backyard. treating the waste is what are the challenges that will need to be processed making sure people are comfortable with having this technology around them. but ok, thank you, good to get your take on that event taking place this week. ahead of cop 28 there's been much discussion about ways of limiting the amount of carbon dioxide we release into the air around the world. but there is also a wave of technology being developed which aims to take the co2 that is already in the air, out of the atmosphere. adrienne murray reports. trillions of tons of greenhouse gases have already been pumped into the atmosphere. but what if we could put some of that carbon back where it came from? this otherworldly landscape is 30 kilometres from iceland capital it is turning it into stone. called or the plant is owned by swiss form pine works and consists of eight container size module. this is the world's first direct air capture and storage plant in existence so it is the only ones operating on a commercial level. it is a plant that captures carbon dioxide directly from the atmosphere. fans draw air across a special filter that separates the co2. it is heated to 100 degrees and said through a processing hall before it is piped across inaudible for storage. direct air capture is expensive technology. these machines need round—the—clock power to remove 4000 tons of co2 each year. that are similar to the emissions of 900 petrol cars — though not an awful lot. this is the first of its kind but is here to prove a point that this is commercially viable. now our plan is to scale up because we need to be capturing at gigaton levels by 2050. in order to do so we need to start now. close by, a new installation is being built called mammoth, it is almost ten times bigger. big tech firms are among the clients and individuals who sign up online. though client works insist this is no silver bullet.— is no silver bullet. we're not here to replace _ is no silver bullet. we're not here to replace reduction - is no

revolution. dozens of new - technologies are trying to that but so far this efforts are highly. we both need to mitigate as much as we can and then we need these new techniques but they are definitely not at that scale yet. there are many limitations, mostly about land use, scalability, price, resource use as well. carbon removal may seem like a moonshot but if it can be scaled up it could yet prove to be a crucial weapon in the fight against climate change. let's get some of the day's other news now. charlie munger, the longtime vice chairman and second—in—command to warren buffett at berkshire hathaway, has died at the of 99. mungerjoined berkshire hathaway in 1978, and helped transform it from a small textile company into a gigantic conglomerate, now valued at more than $780 billion. the us dollar has hit a three—month low as investors have grown increasingly confident that the us federal reserve will start cutting interest rates by the middle of next year. the us currency dropped 0.5% against a basket of six other currencies to trade at its lowest level since mid—august. the decline accelerated after christopher waller, one of the fed's most hawkish policymakers, signalled that interest rates were unlikely to rise further and could be cut if inflation continued to slow. saudi arabia's sovereign wealth fund has taken a 10% stake in london's heathrow airport, following the decision by the spanish infrastructure group ferrovial to offload shares in the uk's main travel hub. the shares have been purchased by ardian, a european private equity group, and riyadh's public investment fund. still to come, knocking it out of the park — with global revenues set to surpass $1 billion next year, we look at the commercial success of women's sport. around the world and across the uk, this is bbc news. bbc news, bringing you different stories from across the uk. we are helping about 152 200 families week on week now. a huge average. at the bottom of this property there is a small child that the child needs help so that is what we do. emily only thought her baby bank would last a couple of weeks and finish ones the donations dried up. but almost five years on many starving families rely on it. , they are not coming because they are flash, because they had lots of things, they are coming because they are desperate, because they are desperate, because they need a winter coat for their child, a pair of sturdy shoes. they are coming because they are facing an incredibly challenging circumstances and need that little bit of help.

let's continue with the business coverage. amazon has unveiled its own ai assistant for business customers. the chatbot called 0 can summarize documents, manage cloud services, and power business apps. developed by amazon's cloud computing division, it will cost $20 per user per month. here's michelle fleury from new york. amazon announced 0, a new chatbot for people to use at work, there seems to be a dispute over where the name comes from. some say it is after the james bond movies and some say it is from star trek. either way this is a big deal. amazon may have not built chat gpt but it now has its own generative ai helper which is designed to assist employees with daily tasks, whether it is answering questions about company policy, to coding to summarising strategy documents. crucially, it will compete with other corporate chat bots including copilot by microsoft and duet ai by google. the tech giant also unveiled new ai chips at its annual developer conference in las vegas where taking the stage was the boss of nvidia, a sign of the deepening relationship between these two. amazon said that as well as its own ai chips, it would offer customers access to the latest chips from nvidia. why? amazon is trying to reassert its dominance of cloud computing and is hoping that this will give it an edge over its rival, microsoft. michelle fleury there. what's going on at barclays? on tuesday the unite union said that the bank is cutting 900 uk jobs as it looks to reduce costs. jobs will go across several back—office divisions, including compliance, finance, legal,

a fundamental review is going on at barclays, essentially the question it is asking is how to reduce its dependence on its investment banking division, in a way it is a victim of the success of its banking division because it is the last man standing in terms of a european rival to the big american investment banks. and what has happened is two—thirds of barclays assets are now tied up vestment ranking business, but it is not the most profitable part of the business and the board is under pressure to reduce its exposure to investment banking and return some of that money to shareholders. one of the ways they are looking at doing that is reduced the longtail of really unprofitable investment banking business. it is a debate that has gone on for probably 40 years at berkeley �*s ever since
