This week's Tech Life from the BBC World Service explores whether artificial intelligence can help reduce aviation's environmental footprint, focusing on contrails – the cloudy white trails left by aircraft engines that contribute to climate warming. The programme features a discussion with Google about its involvement in Operation Blue Skies, a project using AI to predict and minimise the formation of these harmful trails, highlighting how tech companies are applying machine learning to real-world environmental challenges.

The episode also covers two further topics: an examination of three contrasting approaches taken by phone manufacturers to encourage healthier relationships with mobile devices among children and adults, and an explainer on how AI detection tools work. The 26-minute episode is presented by Shiona McCallum and produced by Tom Quinn.
