Huge cost variation between negative emission technologies (15-75th percentiles): * Afforestation 5-50 USD/tCO₂ * BECCS 100-200 * Biochar 30-120 * DAC 100-300 * EW 50-200 * Soil Carbon 0-100
I often get asked for the marginal abatement cost curve for carbon removal solutions. This graph from
showing scale/cost ranges for solutions is one reason why this graph is so hard to make robustly....
Huge range in removal potentials for different negative emission technologies (15-75th percentiles): * Afforestation 0.5-3.6 GtCO₂/yr * BECCS 0.5-5 * Biochar 0.5-2 * DAC 0.5-5 * EW 2-4 * Soil Carbon 2-5
2. The literature on NETs is growing rapidly & diversifying A few things of interest: * The death of ocean fertilisation? * Soil carbon has huge literature, but 1 cost estimate!
* BECCS & DACCS of similar trajectories (despite BECCS dominating scenarios)
