DAC costs for the two most common removal strategies are $90–$220/tCO for chemical processes 2 BEC (bioenergy with carbon capture) is the production using solid materials to absorb the CO from the air and 2 and use of plant biomass as a feedstock for supplying $150–$600/tCO for chemical processes using liquids 2 energy, through either combustion or fermentation and to dissolve the CO out of the ai. [...] Another BiCRS approach is ocean iron fertilization emissions associated with growing the biomass, and for to promote phytoplankton CO uptake; the storage BECCS and BiCRS, emissions associated with collecting 2 occurs when the phytoplankton die and fall to the ocean and transporting it. [...] The duration of forest carbon The design of the IRA does not ensure that funding sequestration is inherently impermanent because of will be directed toward afforestation, the most effective trees’ natural or harvested life cycle and the potential for land-based CDR investment. [...] The capability to purchase and sell removal GHG mitigation, accounting for all spillover effects: if the credits would provide the needed economic incentive for marginal costs differ, then the same degree of reduction in CDR investments—an incentive that would otherwise not 14 The government also would have to adjust bid prices to account for any external effects of CDR. [...] In the interest of distributional equity, One effective way to create incentives for private the overall effects of emissions mitigation and removal investment in CO removal is to set net-emission 2 costs on different portions of the population need to be targets and allow volumes of CO removal to offset GHG 2 carefully assessed, with other tax and transfer policies mitigation requirements.
