This work provides a simple physical framework to analyze the challenges related to achieving a net-zero carbon dioxide (CO₂) emission target, with a specific focus on CO₂ management solutions based on CO₂ capture and storage (CCS), biomass use with CCS, and direct air capture of CO₂ from the atmosphere with permanent storage. The framework is based on a simplified schematic of the Earth system, a simple mathematical model of such a system, and a graphical representation of it (called a scenario diagram), where the states of the Earth system can be mapped, from the net-positive world of today to any net-zero and net-negative future scenario.
