Bridging carbon removal time lags in agricultural enhanced weathering via methane emission reduction

Enhanced weathering (EW) shows promising signs of delivering durable carbon dioxide removal. This pathway may be able to rapidly scale by tying into existing farm infrastructure while providing clear co-benefits to growers. However, in many EW deployments, the shift in radiative forcing is offset from the investment in the deployment. This radiative forcing time lag complicates using the practice to offset carbon emissions. Here, we suggest that coupling EW with enhanced methane destruction provides a robust framework for carbon credits. We provide examples of how this framework could provide continuous and immediate offsets of anthropogenic emissions.
