Are People Driving Their Own Cars Less to Decrease Global Warming Impact?

By    |   Sunday, 08 Mar 2015 07:10 AM

Concerns over cars and global warming have driven environmentalists to encourage people to use their vehicles less. One study says the average number of miles Americans drive per capita has indeed decreased in recent years, with young people in particular saying they are driving less in an effort to protect the environment. Still, census figures indicate the United States has seen a decrease in carpooling, which is a key strategy for reducing driving mileage.

Global warning gained significant media coverage and public attention after NASA scientist James E. Hansen testified before Congress in 1988 that he was 99 percent sure a long-term, worldwide warming trend was underway and he suspected greenhouse gases were responsible, said the American Institute of Physics.

Urban planners – who were already encouraging carpooling and the use of public transportation – subsequently thought they were getting some help when amendments made in 1990 to the federal Clean Air Act would have required many companies to develop plans to increase carpooling and mass transit use, said the New York Times. But the Times said Congress, after hearing from critics who said the proposal was unworkable, scrapped the requirements in the mid-1990s.

Census figures show the percentage of Americans who carpool has fallen from about 20 percent in 1980 to under 10 percent in 2012, according to the Wall Street Journal.

Still, a 2012 study by the Frontier Group and the Public Interest Research Group concluded the average number of vehicle miles driven per capita in the United States decreased by 6 percent between 2004 and 2011. The study said young people in particular were consciously making the choice to drive less in an effort to reduce their environmental impact. It reported people between the ages of 16 and 34 took 15 percent fewer trips in 2009 than people in that age group took in 2001, adding that the average trip length for people in that age group in 2009 was 9.5 miles, compared to a 10.1-mile average trip length in 2001.
