The climate impact of aviation emissions is a topic studied intensively due to its importance for a sustainable society. Climate-optimized routing of aircraft aims at minimizing climate impact. However, in reality, current routing models in the airline industry tends to optimize the financial cost of operation with little consideration on the environmental sustainability. To support governments and airlines in finding a practical solution to this trade-off between the financial and environmental costs, a product for the calculation of multi-objective flight trajectory optimizations is developed at our team. In this study, the flight trajectory optimization is carried out of flights from New York (JFK) to Paris (CDG) over the North Atlantic by using the chemistry-climate model EMAC with the air traffic submodel AirTraf. The compromise solutions in terms of the Pareto front or, more precisely, the nondominated front are analyzed. The talk also introduces the EMAC model in its first part.
