Summary

To limit global warming to 1.5 K above the preindustrial level and to draw down temporary overshooting
greenhouse gas (GHG) emissions or balance them, large-scale land management with bioenergy
plantations is necessary to achieve negative emissions (NE). However, altering biospheric land use at a
global scale may threaten other global sustainability goals (SDGs, e.g. world population food demands).
Using biomass for producing bioenergy plus biochar offers the option to combine C sequestration with
economic value generation which is not the case when bioenergy with liquid CO2-capture and geological
storage is used. Biomass carbonization (pyrolysis) technology can readily be deployed from rural-decentral
up to industrial scales. The project quantifies the global potential for biochar-CCS by biomass plantations
and agriculture, with a special focus (for land and water use) on SDGs (human nutrition, ecosystem
protection).
