“…However, these two studies suffer from incomplete modeling of the effect of pyrolysis temperature on biochar stability. Their results must be contrasted by results from Thers and colleagues [249], who found a higher climate mitigation potential for high temperature biochar in their more thorough modeling of the effect of pyrolysis temperature (decrease in biochar yield but increase in biochar's carbon content and its stability and increase in bio-oil yield).…”

“…This may be due to a lack of compiled carbon stability data at the time of the LCA studies as the meta-analysis of biochar stability are from 2016 and 2018 [18,20] or to a choice of keeping conservative assumptions. Thers and colleagues [249] showed that carbon sequestration is increased at higher pyrolysis temperature by 10% from 400 • C to 800 • C.…”

“…A common finding is that biochar is more likely to stimulate ecosystem services in deprived soils than in fertile soils and well-managed cropping systems [6,7]. However, even in fertile soils, biochar application can be pursued to improve greenhouse gas balances, as biochar contributes to long-term carbon (C) storage [8,9] and might reduce soil emissions of nitrous oxide (N 2 O), which often compromise the environmental sustainability of intensive cropping systems [9].…”

“…Land application of biochar as a soil amendment has recently drawn increased interest in the scientific community because of its perceived potential to reduce GHG emissions (Harter et al., 2014; Thers, Djomo, Elsgaard, & Knudsen, 2019). However, results among studies evaluating the effects of biochar on GHG emissions are inconsistent (Abbruzzini et al., 2017; Case, McNamara, Reay, & Whitaker, 2012; Case, McNamara, Reay, Stott, Grant, & Whitaker, 2015; Zhang et al., 2019).…”
