To help tackle the climate crisis, we'll need a lot of new technology to reduce the concentration of greenhouse gases in the atmosphere. Ellie, Jasmin and Laura share a load of facts about the chemicals, energy requirements and land use involved in technology to capture carbon dioxide from the air. They also look at how planting trees compares to this technology and answer questions from a live audience from the Engineering Development Trust about Taylor Swift's private jet and why we're spending money on projects that aren't tackling the climate emergency.
Read the review article that Laura mentions in the journal MRS Energy & Sustainability.
