WebThis chapter deals with the evolution of global ozone outside of the polar regions. The increase of ozone- depleting substance (ODS) concentrations caused the large ozone decline observed from 1980 to the mid- 1990s. Since the late 1990s, concentrations of ODSs have been declining due to the successful implementation of the Montreal Protocol.
