Abstract
This study investigates the potential for mitigating the non-CO2 climate impact induced by air traffic operations at the network scale. Due to the spatiotemporal dependency of non-CO2 climate impact, aircraft trajectory planning emerges as an operational strategy to mitigate their corresponding effects. However, trajectory planning without considering the interactions between flights is inadequate when studying the actual climate impact mitigation potential. Indeed, meeting climatically oriented aerial traffic requires a holistic view of different aspects of adopting climate-optimal trajectories. In this study, we aim to assess the network-scale effects of full 4D climate-friendly aircraft trajectories. Different indicators are employed to assess air traffic safety, manageability, cost-efficiency, and the environmental impact of optimized routes. Our findings suggest that while optimized trajectories can potentially reduce climate impact, they introduce significant challenges related to air traffic safety, complexity, and demand, especially in sectors in proximity to climate hotspots. These insights highlight the need to develop an advanced mechanism enabling a safe and efficient air traffic management system with minimal climate impact.
期刊介绍:
Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
