The U.S. Environmental Protection Agency estimates that 2.4 kilograms of CO2 are released when 1 liter of gasoline is burned (20 pounds of CO2 are released when 1gallon is burned). Use this information to determine the number of metric tons of CO2 emitted annually by (a) the car described in Question 1 with a low fuel efficiency, (b) a fleet of 250 million vehicles with this same fuel efficiency, (c) the car described in Question 2 with a high fuel efficiency, and
The U.S. Environmental Protection Agency estimates that 2.4 kilograms of CO2 are released when 1 liter of gasoline is burned (20 pounds of CO2 are released when 1gallon is burned). Use this information to determine the number of metric tons of CO2 emitted annually by (a) the car described in Question 1 with a low fuel efficiency, (b) a fleet of 250 million vehicles with this same fuel efficiency, (c) the car described in Question 2 with a high fuel efficiency, and (d) a fleet of 250 million vehicles with this same high fuel efficiency. These calculations provide a rough estimate of
the CO2 footprints for individual cars and for the entire U.S. fleet with low and high efficiency cars. (Note: 1 kilogram= 2.20 pounds; 1 metric ton = 1,000 kilo grams = 2,200 pounds = 1.1 tons; 1 ton [H11005] 2,000 pounds).
