I was 211, with about 30 of that coming from air travel. They do not have an option for GSHP on heating and cooling, and the thermostat setting did not specify summer or winter. The two are different, of course, and it should be pegged to your electicity/natural gas consumption. I have taken all sorts of different tests on carbon footprints, and they all differ in amounts. "Buying local" for groceries means one thing when you still eat fresh strawberries from the Southern Hemisphere in November, versus eating in season, from what comes out of your backyard, or local farmer's market.

I do not see how my carbon footprint is lower than the world's carbon footprint, or that Vermont's average is lower than the world's average. I assume that this is on a per captia basis.
