Passenger car production currently numbers approximately 40 million cars per year with American vehicles leading the way in car emissions.
A passenger car consumes 581 gallons of gasoline, and emit 77.1 pounds of hydrocarbons, 11,450 pounds of CO2, 575 pounds of CO, and 38.2 pounds of nitrogen oxides.
Even if vehicle fuel economy is increased by 40%, all these gains would be wiped out within 17 years just by a modest 2% annual growth in vehicle miles travelled.
Why, I wonder, are high-horsepower automobiles and SUVs (Sport Utility Vehicles) still manufactured in these worrying days of climate change. With a far worse economy than other vehicles, they still account for a quarter of new vehicles sold. This must mean that one in four Americans who are buying cars either don’t believe in global warming, are still ignorant about it or simply don’t care.
Come on, do you really need a petrol-guzzler? It must be time to change, oh, a round about now, or yesterday perhaps? Go on, you can do it, it won’t hurt a bit – unlike climate change.
