What distinguishes carbon dioxide from other atmospheric pollutants such as carbon monoxide and sulfur dioxide?

Carbon dioxide is classified as a greenhouse gas because it contributes to the greenhouse effect by trapping heat in the atmosphere. In contrast, pollutants like carbon monoxide and sulfur dioxide are harmful substances that can cause health issues and environmental damage.

A strong answer should directly address the approved learning objective to distinguish carbon dioxide as a greenhouse gas from pollutants such as carbon monoxide, sulfur dioxide, oxides of nitrogen and particulates. This question belongs to Atmospheric pollutants from fuels within Common atmospheric pollutants and their sources, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to pollutant, and keeps the wording specific to AQA GCSE revision.
