Astonishingly, the largest category of current on the road polluters is the small car. We ask ourselves why? Well, simply because there are so many of them on the road. Cars in and light trucks our nations are a huge supply of global warming pollution. United States automobiles emit more than 333 million tons of carbon dioxide (CO2) per year, which is more than 1/5 of the nation's total CO2 emissions.
Compared with the rest of the planet, American automobiles emissions are excessively high. With only five percent of the world's population and thirty percent of the world's automobiles, the United States put in forty eight percent of the world's automotive CO2 emissions.
Any true effort to battle global warming has to include cutting automobile emissions. Acting now is crucial to slowing global warming and reducing air pollution.
Americans don't all have to drive hybrids to make a change in our nation. And, while we support everyone to use different forms of transportation whenever it is possible, the certainty is that cars are a big part of our American ways of life.
