How much pollution is caused from a space shuttle launch?

A space shuttle launch generates significant pollution, primarily due to the combustion of rocket propellants. The solid rocket boosters release large amounts of chlorine gas and particulate matter, while the liquid fuel produces carbon dioxide, water vapor, and other gases that contribute to atmospheric pollution. Estimates suggest that a single shuttle launch can emit several hundred tons of pollutants, affecting air quality and contributing to climate change. However, the overall impact of space launches is relatively small compared to other industrial activities.
