Air Quality Tool
The Air Quality Tool empowers airports with cutting-edge air quality assessment techniques to support non-CO2 emissions reduction and improved environmental and health outcomes. It also assists airlines in enhancing sustainability performance through SAF integration, trajectory optimization, and data-driven operational improvements, paving the way toward cleaner and more efficient air transport.

For the local air quality analysis, the tool provides concentration maps associated with aviation attributable emissions for Landing and Take-off Operations (LTO). The main focus is for emissions and air quality impacts near airports.
The maps are obtained from atmospheric simulations which computes how the emitted species evolve in space and time, for a period of one year.
The results are then averaged in time, in order to obtain yearly averaged concentration maps of certain species.
The species of interest for air quality are nitrogen dioxide (NO2), particulate matter (PM2.5), and ozone (O3). Although ozone is not directly emitted from aircrafts, it is present in the background (atmosphere) and interacts with aircraft emissions.
These species are reported to have negative impacts on human health, and are thus of interest to air quality analysis.
