In recent years, the issue of aviation carbon emissions has caused wide public concern. How to measure airline performance under the premise of considering aviation carbon emissions has become a hot issue. In this paper, airline energy efficiency is divided into three stages as follows: operations, services, and sales. A network range-adjusted measure with unified natural and managerial disposability model is proposed to calculate the environmental efficiencies of 29 airlines from 2008 to 2015. We get some interesting results. (1) Scandinavian has the highest overall efficiency among these 29 airlines during 2008–2015. (2) For the other 28 airlines, the improvement of the undesirable outputs is not the most urgent work to improve overall efficiency. (3) The overall efficiency has no obvious fluctuation in this period.

使用网络范围调整的措施以及统一的自然和管理可处置性来实现航空公司的能效措施

近年来，航空碳排放问题引起了广泛的公众关注。在考虑航空碳排放的前提下如何衡量航空公司的绩效已经成为一个热门问题。在本文中，航空公司的能效分为三个阶段：运营，服务和销售。提出了一种结合自然和管理可处置性模型的网络范围调整措施，以计算29家航空公司从2008年到2015年的环境效率。我们得到了一些有趣的结果。（1）在2008-2015年期间，斯堪的纳维亚的整体效率在这29家航空公司中最高。（2）对于其他28家航空公司来说，改善不良产出并不是提高整体效率的最紧迫工作。（3）在此期间，整体效率没有明显的波动。
