Unusual heat sources like the London Underground and data centres are being used to heat and cool cities - they’re called, quite simply, heat networks. The director of one of the largest district heat networks in the UK explores how this could be a major decarbonising solution for population dense places around the world.

The co-founder of Colossal Biosciences makes the climate case for bringing back extinct species like the woolly mammoth and the dodo. Colossal say de-extinction through gene editing techniques could have positive impacts for conservation and improving biodiversity. But the environment has changed completely since mammoths roamed the earth, so we’ll examine how realistic those climate claims are.

Senior fellow at New Delhi based think-tank CSEP, Rahul Tongia, does a deep dive on India. It’s one of the world’s biggest emitters, but it’s also on the frontline of climate change; more than 80 percent of people live in places that are at risk of climate-induced disasters. Rahul explores whether their progress is fast enough, and whose responsibility it is to pay for those changes.

The CEO of Sublime Systems chats about their alternative to make cement. Generating about 8% of all global carbon dioxide emissions, Leah is using an exciting electrochemical process to reduce this figure. It’s used in the buildings around you, the roof over your head and the foundations beneath your feet - so how difficult will it be to reduce these high carbon emissions?
