[CDR] On the trade-offs and synergies between forest carbon sequestration and substitution

Greg and list, and adding Dr. Soimaakallio (first author of the cited paper)
Thanks for the alert.
`The paper is well done. It would be a killer for the biomass portions of CDR - except the authors were unaware of the youngest of the CDR options; biochar.
It happens that Puro has recently chosen a Finnish firm for one of its first CDR options. See
The emphasis here and for most biochar production is on scrap forest material that would otherwise turn back to CO2 and (often first and worse) methane.
Biochar can also operate with farm and urban wastes, but forest resources may be the most important, especially where forests need removal of excess biomass. Maybe not a problem in Finland - but a major issue in the US.
Finland is a wonderful home for biochar - as it is (I think) the country with greatest per capital dependence on forest products. Also rated first (?) in a happiness index. Maybe these statistics are correlated.
