Last Monday, the Department of Energy said that the United States has cut its energy-related Carbon dioxide pollution by three point eight percent last year. This is the second largest drop since 1990. The only recent year with a bigger percentage drop was in 2009, when our nation was facing a recession. According to the Department of Energy, American cars and factories, spewed nearly six billion tons of Carbon dioxide last year. This is down from more than six billion in 2011. It is the lowest level for the United States emissions since 1994.
Energy Department Economist, Perry Lindstrom, says that Carbon pollution reduction is due to warm winter weather, more efficient cars, and a shift from coal to natural gas to produce electricity. Although air pollution continues to be problematic throughout the world, we are heading in the right direction.
