According to the American Public Transportation Association, 1.4 billion is the number of gallons of gasoline public transportation saves the U.S. each year. This represents almost 4 million gallons of gasoline per day.

There is an equivalent of 300,000 fewer automobile fill ups every day because of public transportation use.

Public transportation reduces the nation’s carbon emissions by 37 million metric tons annually equivalent to the electricity used by 4.9 million households. To achieve similar reduction in carbon emissions, every household in New York City, Washington, DC, Atlanta, Denver and Los Angeles combined would have to completely stop using electricity.

4,800 pounds / year, is how much an individual’s CO2 emissions will fall if he or she switches a 20-mile round-trip commute to public transportation. This is equal to a 10% reduction in a two-car household’s carbon footprint.

Use the Federal Transit Administration’s Carbon Savings Calculator to estimate your green house gas savings from taking public transportation rather than driving.

According to the Federal Transit Administration the average American produces 20 tons of Carbon Dioxide per year, or 121 pounds per day. By taking existing transit rather than driving alone, for a daily commute of 10 miles each way, a person would save 4,600 pounds of Carbon Dioxide per year. This about a 10% reduction in carbon footprint.
