“…In the literature, unit fuel use per seat (passenger) or per seat (passenger)-distance is regarded as an important criterion to compute sizes of pollutants emitted, and furthermore to evaluate current operating systems environmentally and economically. In parallel, Loo et al (2014) assess CO 2 emissions of two airports, ATH and HKG, at three scales based on airport, airspace and entire flight levels illustrating further the unevenness of the marginal emissions based on passenger-distance traveled. An important implication in those studies is that aircraft performance, load factor and density of seat configuration are determinants of fuel use and associated emissions.…”

“…However, aircraft fuel consumption and carbon emission factors vary in different phases of flight. To accurately assess GHG emissions in individual phases of flight, this study develops a set of models with reference to methodologies for estimating emissions of aircraft pollutants proposed by Kurniawan and Khardi (2011) and Loo et al (2014). These models calculate carbon emissions from freighter aircraft in individual phases of flight by aircraft type, flight distance, and airport location.…”

“…The take-off phase requires full engine thrust, thus more fuel is consumed (European Environment Agency, 2009). Fuel consumption during these sub-phases of the LTO cycle by different aircraft type can be calculated with reference to Loo et al (2014) and the ICAO Engine Exhaust Emissions databank (ICAO, 2012). To calculate CO 2 emissions during LTO using the ICAO databank, the engine type used must be determined for each aircraft.…”

“…According to the studies, the level of responsibility of countries for the total CO2 emissions of international air transport varies with CO2 emissions per capita of countries. Unfair allocation schemes can lead to market distortion and it's a threat for sustainable development of the industry (ICAO, 2010b;McDougall, G., Roberts, 2012;Loo et al, 2014;Feng-Cai, Li-Gang, and Lan, 2014). According to Feng-Cai, Li-Gang, and Lan (2014) study, "there are huge differences in CO2 emissions of different countries, especially between developed and developing countries".…”

“…According to Loo et al (2014), in international hub airports, because of air traffic congestion, the concentration of CO2 emissions are higher; therefore hub airports should implement more environmental and efficiency improvement measurements. At the same time study of Scotti et al (2014) show that on the whole larger airports are more efficient due to the existence of scale economies at the airport level.…”

The environmental sustainability of the air transport industry, as a key player in global social and economic development, has become a major issue in the agenda of the industry´s stakeholders during the past decade. On both international and local levels, policy makers, scientists and environmentalists, manufacturers and airlines have begun to collaborate on fuel efficiency improvements and greenhouse gas emissions reductions in the sector.This dissertation evaluates the structure and distribution of air traffic in European Union member states. The data presented here has been extracted from the statistical office of the European Union (Eurostat) and databases compiled by the The European Organization for the Safety of Air Navigation (EUROCONTROL). The focus of this study is on commercial air traffic and CO2 emissions in the European Union in 2010 and its evolution through 2013.The extracted data for all EU countries consist of variables such as: number of flights, number of passengers, freight tonnes, revenue passenger kilometers (RPKs) and revenue tonne kilometers (RTKs), fuel consumption and CO2 emissions. The majority of EU air transport traffic is concentrated in six countries: France, Germany, Italy, The Netherlands, Spain and The United Kingdom, which in 2010 represented approximately two thirds of the total EU flights. The data is then segmented per distance bands, at intervals of 500 km to see the concentration of traffic in different distance bands and compare their share with other modes of transport. The fuel efficiency trend in the six largest EU aviation markets from 2010 to 2013 is analyzed and the potential reasons for the changes are investigated. The evolution in the airline fleet composition during the last decade is presented as one of the reasons for the improvement in fuel efficiency, measured by fuel efficiency parameter measuring fuel consumption per RTK (passengers + freight). Additionally, the differences in terms of fuel efficiency among the various airline business models (network carriers, low cost carriers, etc.) and aircraft types are studied. Moreover, future CO2 emissions are projected, taking into consideration three different traffic growth and efficiency improvement scenarios.The results of this analysis indicate a slight reduction in the traffic, both for passengers and freight about (-0.8%) but more importantly, a reduction in CO2 emissions (-4.3%), which is the result of an improvement in fuel efficiency parameters (-3.5%) during these three years. There has been a relevant change in the fleet composition in the last ten years, with the replacement of older models for more efficient ones, and a shift to larger aircraft, particularly in the regional segment. Traffic has decreased in shorter distances (internal EU traffic), but increased in more efficient long-range flights (extra-EU traffic), resulting also in an improvement in the efficiency parameters as average aircraft size and stage length increases. This investigation concludes that technological efficiency in...
