Algebraic and automated targeting for intra- and inter-region problems in terrestrial carbon management network

Abstract

Climate change mitigation is a global challenge. Negative emission technologies (NETs) such as enhanced weathering (EW) are among the promising emerging techniques for CO₂ capture. However, the optimal deployment of EW requires systematic planning tools. In this work, novel algebraic and automated targeting techniques are presented to locate the external outsourced capacity of the EW network. The results of the algebraic and automated targeting techniques may be plotted as the grand composite curve, which has a good visual interface that facilitates planning and discussion. Two examples involving single and multiple regions are solved to elucidate the newly extended methods. When EW sources are integrated across different regions, excess capacity of the EW regions is better utilised, which allows a greater extent of CO₂ capture.
