Measuring the network capacity utilization, energy consumption and environmental inefficiency of global airlines

While several studies have utilized carbon emissions to analyze airline performance, to the best of our knowledge, there have been limited studies simultaneously examining airline capacity utilization, energy consumption, and carbon emissions. The sample of this study comprises 33 global airlines in...
