Method and device for determining and providing a
ranking, according to their environmental
impact, of a plurality of distinct aeronautical flights. The present invention relates to a method (50) for determining and providing a
ranking, according to their environmental
impact, of a plurality of flights comprising - for each flight: -
discretization (58) of its trajectory into a plurality of segments; - for each segment: - determination (64) of the value of the
nitrogen oxide emission index; - obtaining (66) the quantity of
nitrogen oxides emitted on said segment; - obtaining (76) the total quantity of
nitrogen oxides, by summing the quantities on each segment; - conversion (78) of said total quantity into
carbon dioxide equivalent using a predetermined metric and determination (80) of an environmental
impact score; - determination (98) and provision of a
ranking (99) of said plurality of flights, ranked by decreasing value of said
score.Figure for the abbreviation: Figure 2.
