Emissions charges are an effective tool to control aviation carbon dioxide emissions. This paper investigates how airline emissions charges affect a monopoly airline's network choice. By considering simultaneously fully-connected, hub-spoke and mixed networks, we find that the impact of emissions charges on airline network configuration depends crucially on some relevant parameters, for example, the marginal benefit of the reduction of schedule delays and the disutility of additional travel time of connecting flights. Welfare analysis shows a discontinuity in the network configuration from the social planner's perspective and an inefficiency related to the airline's choice on mixed network.

排放收费是控制航空二氧化碳排放的有效工具。本文研究了航空公司的排污费如何影响垄断航空公司的网络选择。通过同时考虑全连接，轮辐和混合网络，我们发现排放费用对航空公司网络配置的影响主要取决于一些相关参数，例如，减少航班延误的边际收益以及对额外网络的无用性中转航班的旅行时间。福利分析从社交计划者的角度显示了网络配置的不连续性，以及与航空公司在混合网络上的选择有关的低效率。
