Occasionally I get asked about where to find calculators to determine climate footprints by teachers or farmers. Here are a few sites that can help provide estimates of your climate footprint. Note that these would not be sufficient for a producer who is trying to show a detailed evaluation, but they can serve as a rough guide to determine how climate-smart your lifestyle is.
Global Footprint Calculator: What is your ecological footprint?
Berkeley: CoolClimate Calculator
FarmFirst Insurance: Carbon Calculator
