“…However, the environmental efficiency of global airlines needs to be improved [52]. Recently, for the sustainability of the aviation industry, it has been emphasized that environmental efficiency should be improved by reducing carbon emissions and by using alternative fuels [17,53,54]. The PTE values were above 0.710, continuing to rise from 2014 to 2018.…”

The study of environmental sustainability in the aviation industry mainly focuses on research targeting specific regions such as the United States, Europe, and China. However, for the environmental sustainability of the aviation industry, global airlines on all continents around the world must implement efficient environmental management. This study divides the world into six continents and attempts to verify environmental efficiency for airlines belonging to each continent. Using data from 2014 to 2018 of 31 global airlines, this study compares environmental efficiency in the aviation industry by continent and individual airline. Data envelopment analysis (DEA), which is actively used in efficiency studies was adopted as an analysis method. We find that, first, airlines in Europe and Russia have the highest environmental efficiency, and airlines in North America and Canada are the second highest, which can be a good benchmark for other airlines. Second, in technical efficiency (TE) values, airlines in Africa and the Middle East and Latin America generally have low efficiency; but, in the airlines in Africa and the Middle East, environmental efficiency is steadily improving slightly. In comparison, airlines in Latin America showed a decrease in environmental efficiency value, requiring a lot of effort and investment to improve efficiency. Third, for airlines in North America and Canada, the scale efficiency (SE) value was the lowest, even though there was a high level of overall environmental efficiency, indicating the need for efficiency improvement through economies of scale. This study has implications, in that, it suggests how airlines can perform efficient environmental management for sustainability according to the continent to which they belong.

“…In literature, energy efficiency and reducing carbon emissions in aviation is a theme that is growing [3][4][5][6]. To reduce carbon emissions in the aviation industry, the International Civil Aviation Organization initiated the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) in 2016, which has taken effect in January [7]. To comply with the CORSIA, it is vital to minimize the energy consumption of belt conveyors in BHTS since belt conveyors form the backbone of most BHTS at major airports.…”

Optimizing the design of an airport baggage handling transport system (BHTS) with respect to the minimization of the total costs and energy consumption is essential to reduce costs and Carbon dioxide (chemical formula CO2) emissions in airport operations. This paper introduces a mathematical model that comprehensively considers relevant costs regarding the operation of belt conveyors in a BHTS. Specifically, the Capital Expenditure (CapEx) and Operational Expenditure (OpEx) are considered in the airport BHTS cost function. Furthermore, to include the impact of CO2 emissions, the offsetting costs of CO2 emissions are included in the airport BHTS cost function. This function forms the basis of an objective function that can be used to optimize the airport BHTS's design by metaheuristic algorithms. Three state-of-the-art particle swarm optimization (PSO) algorithms are utilized to solve the airport BHTS optimization problem. The results of experiments show that the three PSO variants can solve the optimization problem effectively and efficiently. The self-regulation PSO algorithm performed the best in terms of CPU time and has been used for the case studies. Extensive tests of the impact of key parameters, e.g., capacity and system length, on the optimized solutions have been conducted. Experiments show that a system with several belt conveyors of shorter lengths performs better than a system with one long conveyor. In reality however, more parameters play a role like the varying baggage throughput per hour and therefore the BHTS problem needs to be optimized case-bycase. Optimizing an airport BHTS design leads to a significant reduction in CO2 emission and thus costs.INDEX TERMS Baggage handling transport system, airport operations, belt conveyors, CO2 emission, particle swarm optimization.

“…As concerns surrounding the negative impacts of aviation-related CO 2 emissions intensify, a significant shift in policy relating to aviation-induced carbon emissions is on the horizon with the introduction of comprehensive policy. Developed by the International Civil Aviation Organization, the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) aims to control aviation-related CO 2 emissions and will become mandatory for almost all airlines by 2027 [3].…”

“…CO 2 is responsible for the majority of the environmental impact from aircraft jet engines [8], and achieving aviation-related emissions reductions has often focused on improved efficiencies through technological advances. Empirical evidence suggests many ways in which airlines can reduce CO 2 emissions including improving the energy efficiency of aircraft, employing greener aircraft with advanced technology, retrofitting existing aircraft, and developing alternative jet fuels [3,[9][10][11][12][13]. While technology innovations have resulted in a fall in emissions per passenger of over 50% and improved fuel efficiency over the past decade of approximately 2% per year, the emissions reductions achieved through efficiency improvements will be insufficient to offset the increased emissions generated by the increase in the volume of air travel [14,15].…”

Increasing global concern regarding the negative consequences of climate change will see the introduction of comprehensive policy governing aviation-related carbon emissions. With demand for air travel set to accelerate over the next three decades airlines are faced with the task of catering to increased demand while simultaneously achieving emission reductions. In this study we identify the determinants of air passenger flows and flight frequency and assess their impact on carbon emissions and carbon efficiency. Confining our analysis to the European market, we employ Fixed-Effects (FEIV) and Random-Effects (REIV) instrumental variables modelling techniques to 150 intra-Europe routes and find that the factors that are significant in influencing the operational planning decisions of an airline often lead to carbon inefficiencies. Our findings have important implications for both airlines and policymakers. For airlines, we show how the decisions they make to optimise operations can have negative environmental consequences, while we make suggestions as to how policymakers can incentivise airlines to achieve emission reductions.
