Abstract: The preservation of the stratospheric ozone layer is vital for shielding terrestrial life from mutagenic ultraviolet (UV) radiation. While the Montreal Protocol effectively addressed chlorofluorocarbons (CFCs), the rapid expansion of the global aviation sector has introduced a significant, direct source of ozone-depleting pollutants into the sensitive upper troposphere and lower stratosphere (UTLS). This paper examines the chemical and physical mechanisms by which aircraft exhaust—comprising Nitrogen Oxides (NOx), water vapor, and sulfate aerosols—catalyzes the breakdown of O3 molecules. Unlike ground-level emissions, aircraft operate at altitudes where their effluents have a prolonged residence time, allowing NOx to engage in continuous catalytic cycles that destroy ozone more efficiently than at lower altitudes.
