It has become increasingly clear that halting greenhouse gas emissions will not be sufficient to limit total global warming to less than 1.5 or 2°C over pre-industrial levels – we also need to remove the CO2 that’s already been emitted. The National Academies of Sciences has projected a need to capture and store about 20 gigatons of CO2 per year to limit catastrophic global warming. Panelists will discuss the policy and science landscape of carbon dioxide removal (or negative emissions technologies), with a focus on removing ambient CO2 in the atmosphere and durably storing it in the Earth or converting it into products. This briefing will cover the national policy landscape associated with carbon dioxide removal, and scientists will discuss their work on key Earth-based strategies for carbon dioxide capture and storage, including geologic carbon sequestration, soil carbon sequestration, and enhanced weathering.
Panelists:
Noah Deich, Carbon180
Bill Collins, Lawrence Berkeley National Laboratory
Whendee Silver, UC Berkeley
Hang Deng, Lawrence Berkeley National Laboratory
Jens Birkholzer, Lawrence Berkeley National Laboratory
