Footprintnetwork.org

UThis is a site dedicated to educating people on their carbon footprint. It supports specification (including India, and also supports Hindi). The calculator asks you to select your country of residence and then calculates your carbon footprint based on a set of questions. The good thing about the system is that after calculating and comparing your footprint with your country, the world average and the highest carbon contributers, it tells you ways to reduce your footprint in a "do-able" manner.
