Sustainable Transportation Calculator

How to Calculate Your Carbon Footprint

Your direct carbon footprint comes from the amount of carbon dioxide emitted for each mile of your commute to work and back home as well as additional emissions from running errands outside of work. This calculator does not include indirect sources of carbon emissions from goods or services you’ve purchased. FTA estimates show that single occupancy vehicle trips emit around 0.96 pounds of CO2 per every mile driven compared to 0.22 pounds of CO2 per passenger when vanpooling – that’s 77% fewer emissions if you switched from driving to vanpooling. Non-work trips including errands, recreation, family trips/vacations, and other non-work trips typically average about 10 miles per day.
