You're probably already clued into how to minimize your footprints in many ways, but it never hurts to have a repository at your fingertips, right? This is a living, changing page. If you have something you want to see added here let me know. 

Favorite Calculators

Carbon

This one is robust and provides lots of details about what you set into motion.

Earths

This asks you details about you and then calculates how many Earths would be needed if everyone lived like you. 

Plastic

I have yet to find a calculator that is as nuanced as the others. This is my fave so far.

Slavery

This calculator is a bit  finicky. I recommend going landscape on your phone or trying a tablet or computer. It's worth it, as it has a lot to teach about our market place.
