As the global community seeks viable solutions to achieve climate stabilization, understanding the dynamics of the Earth’s carbon cycle is essential. This talk introduces the Reaction Network Carbon Dioxide Removal (RNCDR) framework, an application of Chemical Reaction Network Theory (CRNT) to global biogeochemical modeling. We construct an integrated system-level model comprised of a pre-industrial carbon subnetwork, anthropogenic emissions, and specific modules for carbon capture and storage. We specifically analyze two critical NETs: Bioenergy with Carbon Capture and Storage (BECCS) and Direct Air Capture (DAC). Our results suggest that despite their differing physical implementations, these two distinct methods share remarkably similar network properties. We demonstrate how both systems can exhibit steady-state multiplicity and absolute concentration robustness in key species. These findings provide a theoretical foundation for understanding the dynamics of large-scale carbon removal interventions.
