The chart shows average _CO2CO₂ emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas-electric), as well as electric vehicles. The abscissa is mg _CO2CO₂ per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, _CO2CO₂ emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little _CO2CO₂ associated with its production. California has the lowest _CO2CO₂ emission for producing electricity, and Ohio has the highest because it depends heavily on coal-fired power plants.

The chart does not include _CO2CO₂ emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, _CO2CO₂ emission associated with manufacturing electric vehicles is estimated to be 25-75% 25-75% greater than _CO2CO₂ emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, _CO2CO₂ emission associated with electric vehicles driven in Ohio would be about equal to that of gasoline vehicles.
a. True or false? During its lifetime and including manufacturing costs, electric vehicles driven in Ohio emit about the same amount of _CO2CO₂ per mile driven as gasoline vehicles of the same curb weight.
b. A mile is 5280 feet 5280 feet and a foot is 12 inches. 12 inches. Use Table 1-4 to find out how many miles are in 1km. 1km.
c. Convert 1 mg CO21 mg CO₂ per mile per vehicle pound mass into mg _CO2CO₂ per km driven per kg vehicle mass. Use Table 1-4 to convert pounds to kg.
d. Consider a vehicle with a mass of 1.5 metric tons. 1.5 metric tons driven 150000 km. 150000 km. (A metric ton is 1000 kg.)1000 kg.)  Calculate the total _CO2CO₂ emission (in metric tons) from driving this car if it uses gasoline or if it is an electric car driven in California. This comparison does not include _CO2CO₂ emitted in manufacturing the car.
