Say you live 15 miles away from work. You work 245 days a year. 1 miles is about 1 lb of carbon emissions. You live in a situation where you emit 7350 lbs of CO2 a year from emissions. If you carpool with 1 other person, you now have halved your emissions. 3675 lbs of CO2 in comparison to the 7350 lbs you used to emit. Congratulations!
The way to calculate how many lbs of CO2 emissions you prevent
(Miles to work x 2 x days you work a year) – (miles to work x 2 x days you work a year ÷ the number of people you carpool with)
