[Gasification] Biochar - Carbon Negative?

After gasification, approximately 5% of the woody biomass remains a biochar
which sequesters carbon, hence a 'carbon negative' claim can be made.
Alternatively, if the woody waste is left to rot in situ, the carbon
sequestration is 0% (all carbon is released/transformed into CO2 and other
gasses).

True?
