Fig. 6. Cumulative GHG emissions reduction during 2020–2050 compared with BAU and cumulative GHG emissions.

Fig. 6

The net life-cycle GHG emissions are studied taking account of carbon fixation by biochar/carbon storage by BECCS, life-cycle GHG emissions for a BIPP/BECCS system and biochar soil effect of biochar sequestration (see “Method”, Eq. (2)). The GHG emissions reduction is attributed to biochar production in the studied pyrolysis (BIPP) systems or/and BECCS (including fossil fuel offset and net life-cycle GHG emissions). Results are shown for seven scenarios, in which solid lines indicate the scenarios under “Moderate development of bio-NETs”, dashed lines under “Maximum bio-NETs potentials”.
