Overall, the energy used in BECCS adds about 30% to the carbon emissions to the atmosphere from burning biomass directly.
Suggestions that we can mitigate the impact of fossil fuel combustion by increasing carbon storage in soils are bogus.
Trees remove a lot of carbon dioxide from the atmosphere
Recent press coverage of soil carbon sequestration on farms creates the dangerous impression that we can easily store a significant fraction of CO2 from fossil fuel emissions through better soil management.
Policies devoted to bioenergy should be redirected toward efforts to protect terrestrial carbon stocks and recarbonize the biosphere.
If we are to store carbon in soils, better management of agricultural lands might be one avenue to pursue.
