Not sure it’s about cynicism as much as about understanding what's going on.
The amount of CO2 sequestered is about 80 cars/year worth, and I’m not sure if that accounts for the thermal decomposition reactions, transport, or other steps involved with bio oil production. (Worth noting the “bio oil” is not a usable product, as Charmful says on their website it’s a waste product they’re burying in the ground.)
Say they had 1MM Stripes, operating at 10^6 scale, e.g. 80,000,000 cars worth, it would still actually make no difference, reducing yearly global CO2 output on the rough magnitude of .000001%.
Not sure what else to say.
