Personal Carbon Footprint
This is a good app to determine your carbon footprint in tonnes per year using own consumption, spend data in detail. Gives main category results and compares you to major countries and world average. Suggests how to reduce footprint in many examples. J. Robins PhD, Bellingham, WA.
Lacking inputs, targeted to Europeans
This app does not work for my living circumstances - common ones in Canada: living in an apartment building that has shared heating across the whole building, and separate electricity supply from heat. It does not ask about things like needing to idle vehicles (needed to allow them to warm up in cold temps but also very abused where I live). Despite picking my country, the expenses entries only allowed for inputs in euros which is cumbersome to have to convert. Given this, I also can't imagine that dramatic differences in costs of consumer goods between countries and even regionally across big countries like Canada are accurately accounted for.
