Eco-efficient aircraft trajectories to reduce aviation non-CO₂ climate effects under varying atmospheric conditions

Global mobility offers significant benefits to our society. It enables solutions to reduce inequalities, for example, providing access to high quality education and work opportunities. From this point of view, aviation plays a crucial role in the social and economic development. However, only a small fraction of the global population currently accounts for more than half of the total civil aviation emissions, which negatively affects local air quality and the Earth’s climate. In recent years, there has been an increasing pressure to mitigate the environmental damages from aviation, mainly by limiting its carbon dioxide (CO2) emissions. This greenhouse gas is responsible for long-term warming effects, as it remains in the atmosphere for years to millennia....
