Driving in a relatively fuel efficient car (25-30 miles per gallon) usually generates fewer greenhouse gas emissions than flying. In assessing the global warming impact of a trip from Philadelphia to Boston (about 300 miles), the environmental news website Grist.org calculates that driving would generate about 104 kilograms of carbon dioxide—the leading greenhouse gas—per typical medium-sized car, regardless of the number of passengers, while flying on a commercial jet would produce some 184 kilograms of CO2 per passenger.

Builds up a case in favour of car pooling.
