4Faced with the growing concerns of the public related to pollutant emissions and health issues, the aviation sector, and in particular airports, must adopt an effective strategy to address this matter. Indeed, emissions from aircraft and other emission sources at an airport have an effect on the local air quality (LAQ).

In particular, the most important contributors on LAQ concerns are :

  • emissions of nitrogen oxides (NOx),
  • volatile organic compounds (VOCs),
  • carbon monoxide (CO),
  • particulate matter (PM).

However, the airport is not the only source of emissions. Usually airports are surrounded by road networks and supplied by power stations and other industrial facilities. The airport is therefore not the only, and often not even the major, responsible for all the air pollution measured in the area.

The pragmatic solution to understanding the contribution of an airport to the measured air quality at any point around it is through modelling.

Envisa has been one of a small group of experts participating to the development of international guidance and tools to support Airport Local Air Quality Studies.
