Chlorine is well-known for its destructive effects on ozone in the atmosphere, particularly due to its role in ozone-depleting substances known as chlorofluorocarbons (CFCs). When these compounds are released into the atmosphere, chlorine atoms are liberated through photodissociation, a process catalyzed by ultraviolet (UV) radiation. A single chlorine atom can break down thousands of ozone molecules, leading to significant depletion of the ozone layer, which protects the Earth from harmful UV radiation. This interaction highlights the critical role that chlorine plays in the ongoing concerns regarding ozone depletion and its environmental consequences.

In contrast, carbon dioxide and methane are not effective at destroying ozone; they are greenhouse gases that contribute to global warming. Nitrogen, while abundant in the atmosphere, does not have a significant impact on ozone depletion either. Thus, the presence of chlorine is key to understanding the mechanisms of ozone layer depletion.
