Abstract Aviation contributes to anthropogenic climate change through carbon dioxide (CO 2 ) and non-CO 2 emissions. Due to dependency on atmospheric conditions, the non-CO 2 climate impacts can be mitigated using aircraft trajectory optimization. However, adopting independently optimized trajectories may not be operationally feasible for the air traffic management system due to the associated impacts on the safety, demand, and complexity of air traffic. This study aims to explore the effects of employing climate-optimized trajectories on air traffic complexity in terms of the number of conflicts and propose a strategic resolution based on speed change to resolve the conflicts that arise. A scenario with 1005 flights is considered as the case study. The results indicate that the adoption of climate-optimal trajectories increases operational cost and the number of conflicts. Employing the proposed resolution algorithm, it is shown that the conflicts can be resolved by accepting slight increases in climate impact and cost.

    Highlights The climate impact of non-CO2 emissions can be mitigated by trajectory optimization. Adopting trajectories with less climate impact increases air traffic complexity. A strategic resolution is proposed based on speed change to resolve the conflicts. Employing climate-friendly trajectories reduces the potential to resolve conflicts.
