I've seen a few "carbon footprint" meters on the internet in my searching. Usually, they are focused on your travel, heating/cooling, etc. These types of measures are great for a household or family, but not always representative of individuals living in an apartment complex or college campus. The ecologic footprint calculator I'm posting here is great because it includes other choices individuals make everyday, like food, housing, and travel. It also shows you ways you can reduce your overall ecologic footprint.
Plus, you can design a character and watch her/him walk all over the screen! Great fun! Let us know what your ecological footprints are, and any resulting changes you may make in your lifestyle as a result.
