In recent years, the global commitment aimed at reducing the environmental impact of all human activities, is increasingly growing: it is therefore in this perspective of farsightedness that aeronautical activity must evolve, setting as an objective of equal importance the satisfaction of users and also a limitation of the direct and indirect emission of pollutants. While on the one hand technological innovation has led to the development of innovations in propulsive terms, thus allowing to travel at hypersonic speeds in accessible commercial flights, on the other hand it has made it necessary to create new techniques for analyzing and forecasting pollutant and greenhouse gas emissions right from the conceptual design phase.
