Want to know how big of an impact you're making on the environment? Use the carbon footprint calculator at CoolClimate.berkeley.edu.
A carbon footprint is a measure of the greenhouse gases released in the production, use, and disposal of everything you consume. This includes emissions from transportation, household energy, waste, water, food, goods, and services. Developed by researchers at the University of California, Berkeley, with financial support from the California Air Resources Board, this online tool helps you quickly compare your household carbon footprint to similar households in your zip code, city, or state, and then prioritize the things you can do to reduce your climate impact. Also see the CoolClimate interactive map to compare the carbon footprint of different zip codes in the United States.
