Total Tons of CO2 Produced = Bus Miles Traveled * Bus Emissions Factor

Bus Miles Traveled
We calculate the distance between the ‘from’ and ‘to’ locations you entered to determine miles traveled. Or, if you entered an ‘actual mileage’, we use that number.

Bus Emissions Factor
Depending on whether your bus travel is local or intercity, we apply a CO2 emissions factor of 0.0172 lbs or 0.66 lbs of CO2 per passenger mile, respectively. This gives us the direct CO2 emissions from your bus travel. [These factors are from the GHG Protocol Commuting Emissions Tool v 1.2]
