Will airlines' pollution abatement costs be affected by CNG2020 strategy? An analysis through a Network Environmental Production Function

- A Network Environmental Production Function is built.
- The impacts of CNG2020 strategy on 29 global airlines' pollution abatement cots are analyzed.
- CNG2020 strategy will have an evident influence on the pollution abatement costs of most of the airlines.

In this paper, we investigate the impacts of the CNG2020 strategy on airlines' pollution abatement costs based on the empirical data of 29 global airlines. We build a Network Environmental Production Function to discuss the change of pollution abatement costs between the situation under CNG2020 strategy and without CNG2020 strategy. The main findings are: 1. Garuda Indonesia is predicted to have the largest pollution abatement costs while Lufthansa is predicted to have the best performance during 2021-2023. 2. CNG2020 strategy is predicted to have an evident influence on the pollution abatement costs of most airlines.
