"Public transport (excluding air travel) allows lower emissions of air pollution, contribution to better air quality, noise reduction and reduction in emission of greenhouse gases. A 2002 study by the Brookings Institution and the American Enterprise Institute found that public transportation in the U.S uses approximately half the fuel required by cars, SUV's and light trucks. This is because public transport is more energy efficient, both due to economies of scale, but also because it can use low-friction infrastructure such as rail and water, combined with electric traction." - Wikipedia
