Getting to neutral - options for negative carbon emissions in California

Lawrence Livermore National Laboratory, August 2020

An assessment of negative emissions pathways— ones that physically remove CO2 from the atmosphere— that can help California achieve carbon neutrality by 2045, or sooner. It addresses practices and technologies for removing carbon dioxide from the air. It also encompasses the entire breadth of strategies, from land management to the latest technological options, and it evaluates the cost of every step of the solution, from waste biomass collection to carbon dioxide transport and geologic storage. It includes comparison of gasification, pyrolysis and anaerobic digestion technologies.
