"As it is a plant-based CE option that extracts CO2 from the atmosphere, it might be considered a ‘green’ CE method that moves the biosphere closer to its natural, i.e. pre-Neolithic, state. Here, we test this hypothesis by comparing the biogeochemical (water- and carbon-related) changes induced by biomass plantations compared to those induced by historical human land cover and land use change. Results indicate that large-scale biomass plantations would produce a biogeochemical shift in the terrestrial biosphere which is, in absolute terms, even larger than that already produced by historical land use change."
