Has anybody calculated the Shuttle's atmospheric pollution in terms

Back when the ozone layer was the issue of the day, someone asked
whether the shuttle could have its cargo bay filled with ozone then
dump it at the right altitude. The answer which came back from NASA
was that the damage to the ozone layer caused by the SRBs would almost
exactly equal the shuttle load.

Sorry, it was over a decade ago, so I've got no references.

Also, other people have talked about the environmental cost of the
electricity used to split the H2 using electrolysis. That is not how
H2 is currently produced in industrial quantities. It is tapped from
oil production. http://en.wikipedia.org/wiki/Hydrogen
