This episode is about the real world feasibility and consequences of two greenhouse gas removal approaches: first, large-scale afforestation, and second, biomass energy with carbon capture and storage (BECCS). They both play the largest roles of any greenhouse gas removal approaches in future low emission scenarios that keep global mean temperature increase to below 1.5 °C and 2 °C. We have three guests for this episode Nem Vaughan, Clair Gough and Diarmaid Clery from the FAB-GGR team or the Feasibility of Afforestation and Biomass Energy with Carbon Capture and Storage for Greenhouse Gas Removal. Clair is senior research fellow at the University of Manchester where she has worked for many years on carbon capture storage, looking at everything from the social and political aspects to its role in decarbonising industry and removing carbon dioxide. Diarmaid is a research associate at the University of Manchester, and previously worked at the University of East Anglia. His background is in engineering, working on technical aspects of  biomass energy with carbon capture and storage (BECCS), but now working on more social aspects of greenhouse gas removal, and industrial decarbonisation. Nem is an associate professor at the University of East Anglia where she works on greenhouse gas removal methods, from an earth system perspective through to public and policy.
