Hard to imagine cheaper than planting trees -- but turning atmospheric carbon into rock takes it out of circulation permanently, and with effectively no space constraint.
- bodhiandphysics 5y agoPlanting trees is more expensive than you think! You have to buy the land, maintain it, actually physically plant the trees ( which is rather labor intensive). Plants are a relatively low density place to store carbon ( compared to say carbonate rock). It’s not at all clear that planting trees is a good way to sequester carbon.
- homo_nullius 5y agoIt's not enough to plant trees. Fallen trees rot and release CO2 back in the atmosphere. You need to cut the trees down, then use lumber for building something, and bury the rest so that it does not decompose.
