Episode notes

The main aim of ClimbWorks is not to make a profit, says Christoph. If the tech is too expensive, it will limit who makes use of it and whether it can scale up in time. There's another big issue though with carbon removal tech: Some of its biggest cheerleaders are fossil fuel companies. They see it as a way for the sector to cut carbon while continuing to extract more fossil fuels.

In this episode of Tech Tonic Pilita Clark visits Iceland to meet the engineers and scientists at the forefront of this new tech. Can carbon capture scale up quick enough to have an impact on climate change, or is it just an excuse to allow fossil fuel companies and emitters to keep polluting?
