Short summary
This study presents a new bottom-up model to estimate emissions and banks of long-lived ozone-depleting substances. It is applied here to HCFC-141b. Calculated global emission trends are qualitatively consistent with atmospheric observations from 1990–2017. However, they diverge after 2017, suggesting either a growing additional source or a model deficiency. The easily recoverable portion of the bank is projected to be smaller than previously estimated, impacting future recovery feasibility.
