the bbc reporter michelle fleury has more on the story. the road has not been easy. the last time elon musk took to the stage to promote the company's cyber truck, its windows ended up being smashed. four years later, as the company starts delivering the futuristic product to buyers, the problem has been fixed, with customers there in person at the tesla factory there in austin, texas, there to collect their cyber truck. elon musk put on a show to mark this historic moment. this video shows a cyber truck beating a porsche in a drag race while towing a porsche. but tesla's entry into the lucrative us stock market ——truck market is some two years behind schedule, at a time when high interest rates have dampened buyers�* ability to make new purchases. the cheapest model is $61,000. elon musk said the company has more thani million reservations and although the cyber truck is not expected to turn a profit for several years to come, given the enormous challenges in actually making it, the launch is an important part of the broader, bigger tesla story, proving the electric car maker can expand its range of customers in the years ahead. in other news this morning, disney ceo bob iger says his company's partners and creative team have been prioritising messaging over storytelling and that enough is enough. this comes after a slew of online criticism, as well as from republican politicians, in past years like lighyear in 2022, which included a same—sex kiss. the company's marvel cinematic universe has been lambasted by a small section of comic fans for putting out content, ——too much content emphasising quantity over quality. the ceo says they have lost sight of their number one objective, which is "to entertain first. "it is not about messages." in an effort to prop oil prices, the world's major oil producers have agreed to cut production by nearly 70,000 barrels a day but describe the cuts as voluntary. brent crude prices have fallen since reaching close to $100 earlier this year, and energy demand is expected to slow next year over the uncertainty of the global economy. the cuts announced account for less than 1% of the total global supply. brazil, another oil giant, is expected tojoin the 0pec plus next year. as we have been reporting all week, the cop 28 climate conference is under way in dubai with global leaders under pressure to take action on global warming. finance is high on the summit�*s agenda and delegates are hopeful of a breakthrough on a climate damage fund proposed by the host, the united arab emirates. the money would in theory help vulnerable nations cope with the cost of climate—driven damage like drought, floods and rising seas, something poorer nations have been calling for. some countries from european union, germany, denmark and the netherlands have already said that they will contribute but also what countries like china to do the same. but funds like this is just one part of the answer to the climate crisis, according to the chief executive of evpn, a network for social investors to focus on issues like gender, inequality and climate. one of the challenges that you referred to in your introduction is that the majority of global funds flows towards mitigation and reduction efforts in the west, which actually leaves adaptation technology is crucially important to support climate resilience underfunded. this issue is further compounded because if you really look at it, a mere 30% of patented adaptation technologies are transferred to developing countries such as those in asia pacific. what about philanthropists and what about the investment coming in from them and how crucial would that be? philanthropic capital is important but what we see is that philanthropists unfortunately even though philanthropic capital is designed to be given away are far less — have a much lower tolerance for risk and they actually look at looking at returns that are much more visible. unfortunately investing in climate requires you to take a much more longer term view and as such, philanthropists to invest more in sectors like education and health where you can see quicker returns on their investment. but climate philanthropy is still important, especially because if you can have catalytic first loss capital to finance innovative solutions around climate mitigation, around climate adaptation, you are going to find that there will be much more appetite amongst investors to then come in. yourteam is in dubai — what are your major expectations? that cop becomes more than a talkshow. i think we're already starting on positive note with a whole host uae announcing their support for a fund that will actually help support poorer countries. we hope that there will be more action items such as this that will take off. we are also announcing our second sustainability seed fund in partnership with google and inaudible which is a pure philanthropy fund to support investments into climate. let's bring you news from india now when shares in data technology have more than doubled in the training debut, valuing the firm at more than $7 billion. it's the first starter group company to go public and almost two decades. investors who got allotments in data technology have taken home a massive profit on day one. this is a company which there was a huge amount of interest because it is for the first time in nearly 20 years that the data group, which are the owners ofjaguar land rover, were coming over with initial public offering. the last time they did that it was with data consultancy services which is now one of india's bigger software giant. data technology is essentially provides technology and engineering support to some of india's biggest automakers in heavy machinery companies and the bumper listing and solid demand for its issue, some say, is reflective of the huge investor appetite there is for quality stocks that are well priced. india's ipo market has seen hectic activity this year with nearly 200 companies going public. a record both domestically and globally, according to reuters. this has happened at a time when india's stock market has been hitting new highs and the country's growth rate is expected to outpace most other countries in the world. a number of new ipos are lined up in the coming months, with analysts saying that the listing rush will continue, at least for some more time. to a special report now on moxilla firefox — if you're old enough to remember was the first most used browser on the internet in the age of dial—up modems but that is not for them to 3%, vastly leaving behind market leaders like google chrome and apple safari. the company behind firefox could lose most of its income because what of its partners is caught in a major court case because what of its partners is caught in a major in the us. my colleague has been speaking to the chair of the bookseller foundation and asked her why it bothers competing with the big guns. ——moxilla we compete on the browser for a few different reasons. it might seem like we love the browser because we have always got it — that is our way through. but underneath that, the browser is an odd peace of software. ——piece the only protection you have is whatever protection the operating system gives you. which had a general level can provide some security and we think firefox is representing you. that's what we do with the browser — everything from protecting you to allow you to change simple things, like websites and bots, to much deeper things that consumers do not experience directly. so we compete because that question of who represents the individual in a highly centralised technological society is critical. your foundation's biggest source of cash is that half $1 billion a year that google pays and at the moment google is on trial in the us where the usjustice department accuses it of unfairly shutting out rivals from the position of being the highly profitable default search engine on web browsers. how concerned are you about the foundation's future given that the trial could lead to the loss of that money from google? there are many reasons to work on revenue diversification. we have been doing that for so long. there is the what you mention, like something catastrophic could happen, but the long—term piece... impact on society is of more positive benefit for society than today, we will continue with that even if the flow of work changes. before we go a quick look at the us markets because a measure of us inflation closely watched by their federal reserve has shown signs of a continued slowdown in october. another signal that the central bank's higher interest rates have worked to rain in consumer spending and inflation. the last rate decision meeting will come later this month and investors are hoping the rate hike and cycle has stopped. ——hiking that is in response to the news that we just gave you. that is all for the moment. you can find more on the bbc news website. thanks for watching and have a great weekend. one of the most iconic buildings in britain — king's college chapel — has been turning heads and craning necks for almost 600 years. but 160 feet up above that scaffolding work started to see it through the next hundred. a year—long conservation of a leaky chapel roof now complete, the focus shifts from to sustainability. we are putting on a38 panels — that is 219 on the south slope and we will be complete by the end of december. what does this mean in real terms? power wise it means an anticipated 123,000 kilowatt hours per year. that reduces carbon emissions by more than 23 times a year — the equivalent of planting over a thousand trees. we are responsible for this iconic building representing traditional. but you know the college is really about education? young people always looking into the future and as we look into the future we know we have to be serious about sustainability. and that is what we really wanted to do anything ——and i think the energy of that came through. i think we caught the moment. but once complete the panels won't change the view, a view that is equally stunning from below and above. for more stories from across the uk, head to the bbc news website. hey, i'm zof with the catch up. tonight, more changes to vapes. some clever tech. and giant pandas. but first, the cop 28 climate summit has kicked off in dubai. it is a meeting held by the united nations each year where world leaders talk about action to tackle climate change. so, what are the headlines from day one? well, the un chief confirmed 2023 will be the hottest year on record — at least £330 million has been promised to areas hit by climate—related disasters and there has also been controversy over the fact that the host country, the uae, is one of the world's top producers of oil. i think the fossil fuel industry has a lot of power over the cop pressers for a long time and i think that this has sabotaged the process, so we need to dismantle this power and give the power back to the people. some other stories now — ...are going to stop selling vapes that taste like dessert and soft drink soon because they have been criticised for appealing to kids. also calling for stricter rules around who can sell vapes and how they are displayed. next, tech has been used to help give people their accents back. until now young people in wales who use devices to communicate have not had a welsh accent as an option but a new programme will allow them to choose between north and south wales accents on the nhs for the first time. and time now for ten seconds of giant pandas — visitors at edinburgh zoo have been watching these guys for the last time before they are sent back to china as their loan is up in december. i am sure they will be hugely missed. they are just adorable. you are all caught up now. see you later. hello. welcome along to sportsday. i'm sarah mulkerrins. coming up on the program: liverpool fire four past lask to book their place in the knockout stages of the europa league. a crunch game to come at wembley and there could be a 50th cap for lauren hemp as england look to keep their 0lympic hopes alive on behalf of team gb. and "it's a crazy game" for ronnie 0'sullivan, who says he "can't be bothered any more" with snooker, despite making the last eight at the uk championship. you're very welcome along to sportsday, wherever you are watching around the world.
