about 100,000 flights jet around the world every day. flying accounts for 2.5% of all carbon emissions. now, that might not sound like much, but if aviation was a country, it would be among the top ten most polluting nations in the world, and its impact is expected to rise. now there s a global race to get clean aviation off the ground. and some companies think they re close to cracking it. pretty soon, passengers will be flying in zero emission aircraft. but how did we get here? archive: the new machine is called, optimistically, - the flyer. we ve come a long way since the wright brothers first flight in 1903. that day, they lifted the world into a new dimension. then we achieved bigger, faster planes. great, but that s also how we ended up with all these emissions. jet engines burn kerosene, which releases carbon dioxide, one of the main greenhouse gases causing climate change. the industry faces an enormous challenge to clean up its act, and that means coming up with new
aviation innovation. this week, lara looks at the elemental solution to cleaning up carbon emissions from aircraft. we travel to the remote faroe islands to look at the latest ways to harness tidal energy. it s sort of like kitesurfing, but on the water. if it moves, it s a controller paul s en route towards more accessible games. if ijust raise my eyebrows, i m making the carjump. and we look at how generative technology could revolutionise the moviegoing experience. it can make approximately 52 quintillion versions of the film. about 100,000 flights jet around the world every day. flying accounts for 2.5% of all carbon emissions. now, that might not sound like much, but if aviation was a country, it would be among the top ten most polluting nations in the world, and its impact is expected to rise. now, there s a global race to get clean aviation off the ground. and some companies think they re close to cracking it. pretty soon, passengers will be flying in zero emission a
for more of this energy hungry infrastructure. also on the show, we re going to get the view from the us tech giant ibm. yeah, they ve seen their demand for al skyrocket. so what are they doing to cut down on their carbon emissions? wherever you rejoining me from around the world, once again, a big hello and a warm welcome to the show. artificial intelligence. yep, ai. it is everywhere nowadays. and the big tech companies like google, meta, microsoft, and now apple, they re muscling in to be at the head of the ai race, unveiling ever more sophisticated chat bots and other machine learning tools. but one aspect of the ai race that s perhaps not talked about as much is the impact on the environment. these language models, like chatgpt, are some of the most energy guzzling technologies. they need vast data centres to store the amount of data required to train the chat bots. so let me just show you some of the numbers. emissions from global cloud computing account for around 2.1%

the institute for fiscal studies, who you may or may not have heard of, it s theirjob, and they re very public about this, aren t they, to test whether or not political parties sums add up. and when you look at it, so i ve got the labour manifesto here and they ve done their costings at the back of the actual book. the conservatives put out a separate book with their costings. there s lots of kind of suspiciously round numbers here because obviously they ve got to do. it s, it s, it s educated guesswork. yeah. a, how much stuff is going to cost? secondly, what the state of the economy is going to be, so, how much growth is there going to be? what does that mean for tax revenues? so there s quite a lot of guesswork. and then, yes, every party, i was at a news conference today that was all about this. every party will then try and trash their opponents and suggest that their numbers are dodgy. so i was at a conservative event today that was trying to do that about labour s mani
