Send me a messageCan we use natural processes to suck CO2 back out of the atmosphere? It sounds tempting because the risks of unintended consequences with processes that have been taking place already on the planet for millennia are significantly lower.One such process is weathering, and a company looking to do Enhanced Weathering thereby sucking millions, and hopefully billions of tons of CO2 out of the atmosphere (while simultaneously improving agricultural land) is UNDO. I invited UNDO's Head of Research Mel Murphy and UNDO's Head of Carbon Simon Manley to come on the podcast to tell me all about it.We had an excellent discussion talking about how Enhanced Weathering works, how it can be monetised, and how UNDO's ambition is to be the first company in the world to remove 1 billion tons of CO2 from the atmosphere.This was a truly fascinating episode of the podcast and I learned loads as always, and I hope you do too.If you have any comments/suggestions or questions for the podcast - feel free to leave me a voice message on my SpeakPipe page, head on over to the Climate 21 Podcast Forum, or just send it to me as a direct message on Twitter/LinkedIn.
