Enhanced weathering with agriculture uses crushed silicate rocks to drive CDR. If widely adopted on farmlands, it could help achieve net-zero emissions by 2050. Here we show, with a detailed US state-specific carbon cycle analysis constrained by resource provision, that EW deployed on agricultural land could sequester 0.16–0.30 GtCO2 yr−1 by 2050, rising to 0.25–0.49 GtCO2 yr−1 by 2070.
