SafeClimate Carbon Calculator

The SafeClimate carbon footprint calculator allows you to determine carbon dioxide emissions from major sources: home energy consumption and transportation by car and plane. Easy to use, with options for entering monthly or annual information (such as miles driven and energy used). Offers separate US and international calculators, and uses carbon intensity factors based on location of electricity source. Ends with a graphic representation and lively animation to show how your footprint compares with others.
