This is a much smarter carbon footprint calculator, 

as it gives you suggestions on how to reduce it, 

depending on the costs of things as a percentage of your expenses

where you live...(USA only I believe, sorry about that, but if we're more aware and act, that's the best possible result!)

In Southern California, where I live, we have zero heating oil expense for example, 

so changing our heating oil habit won't change my footprint.

But if I could quit driving and eating so much meat, better results would occur.

I was at about 70% of the US average for a two person household.

Which made us about 3X the world average...
