Tim Kruger & Dr Steve Smith in conversation: “Beyond zero: the role of negative emission

Oxford Martin School

15 Feb. 2021

Putting the “net” in net zero, nearly all scenarios for climate stabilisation involve not only the reduction of emissions, but also the removal of carbon dioxide from the air. As net zero ambition spreads around the world, attention is rapidly turning to novel technological approaches to removal, as well as more established natural approaches such as planting trees. What are the different ways to remove carbon dioxide from air? How much potential do they have, and how can we scale them up? Perhaps most importantly, will negative emissions be a vital addition to action on emissions or a costly distraction? Join Tim Kruger, Programme Manager of the Oxford Geoengineering Programme, in discussion with Dr Steve Smith, Executive Director of Oxford Net Zero, in this fifth instalment of the Oxford Net Zero series.
