WHO estimates that globally as many as 500,000 people at a time are on planes. The global trend has been for increasing numbers of people to travel by air, and individually to do so with increasing frequency and over longer distances, a dilemma that has the attention of climate scientists and other researchers, the press, and the World Wide Web. The issue of impacts from frequent travel, particularly by air because of the long distances that are easily covered in one or a few days, is called hypermobility and has been a topic of research and governmental concern for many years.

Comparison of the transport mode by distance travelled

Worldwide, the most widely used modes for passenger transport are the Automobile (16,000 bn passenger km), followed by Buses (7,000), Air (2,800), Railways (1,900), and Urban Rail (250). The most widely used modes for freight transport are Sea (40,000 bn ton km), followed by Road (7,000), Railways (6,500), Oil pipelines (2,000) and Inland Navigation (1,500).
