Yes it does. Liquid fuel combustion of the shuttle's main engine emitted carbon dioxide and water vapor - harmless of course and only considered "pollution" because of the incessant drive to add additional, unjustified taxation on energy - but emitted nonetheless.

And, keep in mind a shuttle launch burns the equivalent of about 2 minutes of gasoline consumption of the United States. That's pretty staggering.
