Published by Copernicus Publications on behalf of the European Geosciences Union. 10839 Abstract Hypothetical reductions in future emissions of ozone-depleting substances (ODSs), including N 2 O, are evaluated in terms of effects on equivalent effective stratospheric chlorine (EESC), globally-averaged total column ozone, and radiative forcing through 2100. Due to the established success of the Montreal Protocol, these actions can 5 have only a fraction of the impact that regulations already in force have had. If all anthropogenic ODS emissions were halted beginning in 2011, ozone is calculated to be higher by about 1–2% during the period 2030–2100 compared to a case of no additional ODS restrictions. Radiative forcing by 2100 would be about 0.23 W/m 2 lower due to the elimination of N 2 O emissions and about 0.005 W/m 2 lower due to destruction 10 of the chlorofluorocarbon (CFC) bank. The ability of EESC to be a suitable metric for total ozone is also quantified. Responding to the recent suggestion that N 2 O should be considered an ODS, we provide an approach to incorporate N 2 O into the EESC formulation.
