1 Air Transport Keeps Expanding Michael Renner December 17, 2013 I n 2012 the number of people traveling on airplanes reached 2,957 million, which was 4.7 percent more than the previous year. 1 (See Figure 1.) Although this figure includes a substantial number of people who travel multiple times during the year, it is equivalent to 42 percent of the world s population. 2 The number of passengers is up 95- fold from 31 million in 1950, when flying was a luxury few could afford, and it is triple the 960 million passengers in 1986, when air travel was already quite common. 3 The average length of a flight doubled from 903 kilometers in 1950 to 1,816 kilometers in 2000, but it has not changed much since then and stood at 1,827 kilometers in Longer flights and expanding passenger numbers generated a strong expansion of total passenger kilometers (pkm) traveled up 193-fold from the 28 billion pkm in 1950 to 5.4 trillion pkm in (See Figure 2.) The only pauses in an otherwise inexorable expansion came in (following the September 11 attacks in the United States) and in (after the start of the world financial and economic crisis). 6 vitalsigns.worldwatch.org 1

Like passenger air travel, air freight transport has expanded strongly. In 2012, some 49.2 million tons of goods were transported by plane worldwide.

2 Like passenger air travel, air freight transport has expanded strongly. In 2012, some 49.2 million tons of goods were transported by plane worldwide. 7 Even though this is down 1 percent from 2011, it is 71 percent more than in The Asia-Pacific region, Europe, and North America dominate passenger and freight air transport, accounting for percent of the world total, depending on the precise activity measured. 9 (See Table 1.) vitalsigns.worldwatch.org 2

3 International flights account for the bulk of air transport movements. In 2012, some 39 percent of all passengers were on board international flights, but because of the generally greater distances involved in such flights, cross-border flights accounted for 62 percent of all passenger kilometers. 10 In the same year, 66 percent of freight tonnage was transported on international flights, which accounted for an even more imposing 86 percent of total freight ton-kilometers. 11 According to the International Civil Aviation Organization (ICAO), the world s commercial air transport fleet grew from 18,972 planes in 2003 to 25,252 in 2012, an increase of 33 percent. 12 The largest fleet of aircraft by far is in the United States, which has about 6,000 planes in service, followed by China, with slightly less than 2, All other countries have fewer than 1,000 planes in service each. 14 The bulk of the fleet is for passenger transport. The global airliner fleet is expected to grow considerably reaching more than 36,500 planes by 2032 according to Airbus forecasts and more than 41,000 according to Boeing forecasts. 15 Measured by revenue, 18 of the world s 50 largest airlines in 2010 were from the Asia-Pacific region, 12 were from Europe (including Russia), 11 from North America, 4 each from Latin America and the Middle East, and 1 from Africa. 16 The airline industry has long been marked by a series of mergers. Since the late 1990s, another phenomenon has been the creation of globe-spanning alliance groups Star Alliance, SkyTeam, and oneworld. 17 (See Table 2.) These alliances account for almost 55 percent of all seats flown and 61 percent of available seat kilometers, with even higher shares for longdistance flights. 18 Companies that remain outside these alliances are mostly low-fare airlines and independent regional carriers. Following many mergers and consolidations in the aircraft manufacturing industry, just two companies U.S.-based Boeing and Europe s Airbus account for the bulk of the world s airliner fleet. Boeing has delivered close to 11,000 planes in the last quarter-century, while its rival has sold close to 7, (See Figure 3.) But Boeing has witnessed tremendous upswings and downswings, while Airbus has steadily gained, and during the last decade the two companies have been neck-and-neck competitors. 20 In the market for smaller commercial jets (so-called narrow-body or single-aisle aircraft), the two companies will likely face rising competition from a number of firms such as United Aircraft Corporation (Russia), Commercial Aircraft Corporation (China), Bombardier (Canada), Embraer (Brazil), and Mitsubishi Heavy Industries (Japan). 21 A Boeing forecast suggests that the share of these smaller planes will rise from 64 percent of the global fleet in 2012 to 70 percent by vitalsigns.worldwatch.org 3

4 In 2012, some 49.2 million tons of goods were transported by plane worldwide. In 2013 there were 41,821 airports in the world. 23 The United States had by far the largest number (13,513), followed at a distance by Brazil (4,093), countries in the European Union (3,102), Mexico (1,714), Canada (1,467), Russia (1,218), and Argentina (1,138). 24 A number of South American countries have several hundred airports each, as do Indonesia, South Africa, Papua New Guinea, China, and Australia. 25 However, these raw numbers conceal numerous differences among airports. Many are very small in scale, while a select few have grown into the equivalent of small cities, occupying hundreds of square kilometers, processing millions of passengers each year, and employing tens of thousands of people. Ranked by embarking or disembarking passengers, the world s top 25 airports together served 1.4 billion people in 2012, and they collectively accounted for 12 million of the world s 77 million aircraft movements (takeoffs and landings). 26 Atlanta had the most passengers (95.5 million), followed by Beijing, London (Heathrow), Tokyo, and Chicago. 27 Altogether, 10 U.S. airports are in the top 25 league, followed by 6 European, 4 Chinese, 4 other Asian, and 1ne Middle Eastern. 28 This is a substantial change from earlier rankings. In 2000, in contrast, 17 of the top 25 airports (and 4 of the top 5) were in the United States. 29 The rankings change quite dramatically when only considering international passengers. In the 12 months ending August 2013, London (Heathrow), vitalsigns.worldwatch.org 4

5 Dubai, Hong Kong, Paris (De Gaulle), and Amsterdam topped the listing, each with more than 50 million passengers. 30 By cargo tonnage, Hong Kong (4.12 million tons), Memphis (4.05 million tons), Shanghai (2.97 million tons), Anchorage (2.47 million tons), and Seoul (2.46 million tons) were in the lead in Both the scale of air shipments and the pecking order have changed over the years. In 2000, the largest cargo airports were Memphis (with 2.49 million tons), Hong Kong (2.27 million tons), Los Angeles (2.04 million tons), Tokyo (1.93 million tons), and Seoul (1.8 million tons). 32 Aviation has a range of environmental and health impacts, including noise, land degradation, disturbance of wildlife and biodiversity, and emissions of air pollutants and greenhouse gases (GHG). According to the International Council on Clean Transportation (ICCT), the cumulative climate impact of aviation to date is equivalent to about 40 percent of all surface transport modes, even though motor vehicles are far more numerous than planes. 33 Relative to all sources of GHG emissions, the sector is responsible for about 4 percent of climate change, and its role is rapidly rising. 34 ICCT finds that design changes doubled the efficiency of commercial aircraft since 1960, but that progress has been slow in the last 20 years. 35 This has to do with low fuel prices for an extended period of time, as well as a tripling in the average age of aircraft since the late The cumulative climate impact of aviation to date is equivalent to about 40 percent of all surface transport modes. 1980s. 36 The higher fuel prices of more recent years provide an incentive to reinvigorate efficiency efforts. From levels below 70 per gallon throughout the 1990s, U.S. jet fuel prices rose in subsequent years and spiked at $3.89 in July Following a brief crash in 2009, prices oscillated between $2.62 and $3.28 in the last three years. 38 Still, fuel prices alone are an insufficient and unreliable driver. Government policy needs to provide a push for the development and use of more energy-efficient technologies, such as the global CO 2 standard for new aircraft under development at the ICAO. 39 Broadly understood, airline fuel efficiency is the result of factors beyond technology, including a host of operational practices, load factors, seating density, and routing of flights (compared with the shortest possible travel distance). 40 Thus, all of these dimensions need close scrutiny, and this calls for structural change as well as technical improvements. Beyond this, there are even more fundamental questions about whether the continued growth of the airline industry can be compatible with climate stabilization goals. It may be necessary to curtail both passenger and freight movements, with fundamental impacts on tourism, trade, and the broader economy.
