Transportation was definitely the biggest contributor to my carbon footprint. I live in Livermore so my commute is longer than the average high school student. I take BART to school and carpool on the way home, but I don't think there is any way to reduce my transportation carbon footprint any further without changing where I live or go to school. I think biking and walking to destinations that are close by is a reasonable solution, but it won't fix the problem entirely. Fuel efficient vehicles and eventually alternate forms of energy fueling our transportation should be the ultimate goal.

My issue is the same. I live in Richmond. It takes about 45 minutes to get to school everyday if I'm riding in my dad's car. I recently decided that I'd rather take BART because it will help my father (who's very old) and maybe decrease my carbon footprint.

I also have a similar issue, I don't live very far from school, but I don't carpool or use public transportation as much as I should or would like to. My carbon footprint for transportation was more than three times the average for my region in that category. It was a real eye opener, and showed me that I can make easy changes that can reduce my carbon footprint.

I really like how you listed out all the options you could to limit your carbon footprint even with your obstacle of having a long commute. I don't know if you can but taking the bus and AC Transit are also good solutions to limit your carbon footprint. Making these small steps make a huge difference in our future.
