If you really want to go after emissions, go after the big jet aircraft! Obama going to Hawaii from Andrews AFB will spew over 65 tons of carbon dioxide. Don't forget the aircraft carrying all the limos and other assorted crap. For a freaking vacation. And that is only one way! This is probably why they moved DIA out in the boonies. Stapleton was choking the crap out of the metro area. The leaders all fly in big jets to meet & discuss global warming. Next thing will be all the passengers pissing in a special toilet connected to the jet engines!
