Abstract
Sophie Godin-Beekmann explains the chemical balance that maintains stratospheric ozone and how industrial chlorine- and bromine-containing compounds disrupted it. The seminar reviews the Montreal Protocol and measures aimed at restoring the ozone layer. It also considers the climate consequences of reducing ozone-depleting substances.
