The numbers are finally in. In the month of June County Connection passengers spared the environment of 21,148 pounds of CO2 each weekday. This amount is calculated by multiplying our average weekday ridership for the month by 4 – our average passenger trip length – to determine total miles. This number is reduced by 48% because our research shows that if that bus wasn’t there, not everyone would drive solo. We then use the U.S. EPA figures for average fuel mileage and the amount of CO2 emitted per gallon of fuel (19.4!) to arrive at the final number. Just one person making one trip CAN make a difference big difference.
