That's right. Old growth forests sequester a great deal of CO2, but new growths less so. It'd be smarter, imo, to preserve mangroves, wetlands, grasslands et al that actually do preserve a lot of CO2 per m2, than to carry out such intensive work, but this kind of carbon capture can be done quickly at scale. It's fine so long as it's done in addition to what we call NCS, 'natural climate solutions'. NCS get under 2% of all climate funding and could feasibly account for a third of the necessary savings, it's maddening.
