To calculate the CO² emissions from a gallon of fuel,

the carbon emissions are multiplied by the ratio of the molecular weight of

CO² (m.w. 44) to the molecular weight of carbon (m.w.12): 44/12.

CO² emissions from a gallon of gasoline

=

2,421 grams x 0.99 x (44/12) = 8,788 grams = 8.8 kg/gallon = 19.4 pounds/gallon

(Environmental Protection Agency)

101lb. thrust electric motor ≈ 5 hp outboard engine

5hp outboard engine consumes ½ gallon per hour

5 hours electricity ≈ 2.5 gallons gasoline

2.5 gallons x 19.4 lbs. =

48.5 lbs. CO² Emissions SAVED
