Even we people emit Carbon Dioxide, so ... No, but of course do buses, trains, etc. cause CO2 emissions. But the big question is, how much? Obviously, if the buses and trains run around empty, that's even worse than cars. But there must be a certain threshold at which the emissions per person carried are lower with public transportation than with private automobiles. You’ve obviously got a point there.

My name is Anna and I'm doing some research on Caltrain and Bart emissions. You are very knowledgeable about the CA Transit System, so I was wondering whether you could help me out a bit. Could you possibly point me to some resources that will help me derive/find out how much carbon dioxide buses, Caltrain and Bart emit per mile per person? I'm trying to create an all-encompassing "carbon calculator" that INCLUDES public transportation (as well as cars, airplane rides and what not). I feel as though everyone glosses over the fact that public transportation emits carbon dioxide too - particularly when they use diesel powered engines or electricity from coal/oil/natural gas power plants. I'm also interested in comparing the different alternatives - should I Caltrain, Bart, or Bus? From my preliminary research, it appears as though Bart is a much cleaner alternative than Caltrain...
