Enhanced weathering in agriculture is a potential gigatonne-scale carbon dioxide removal (CDR) pathway, but its potential remains difficult to constrain. The authors used a formal expert elicitation process to estimate CDR potential and efficiency, uncertainties, and key data needs for six feedstocks.
