Planes, Trains, and Automobiles: Comparing the CO2 Impacts

The article discusses and compares emissions from personal transportation, including air travel, buses, trains, and the cars people drive and greenhouse gas emissions from household fuel and electricity consumption, so that one can understand these emissions better, and help make smarter and greener choices. Many online calculators are available to help individuals calculate their household or individual emissions. These calculators tend to focus on types of emissions, household fuel and electricity use, vehicle fuel use, and air transport emissions. Often one will be surprised to find that emissions from air travel, were greater than the fuel- and electricity-related emissions from the house, and greater than the emissions from the cars.
