“It is the branch of Environmental Science and which is concerned with the study of the impacts and interactions of the all activities of the Air Transport Industry on the environment and living organisms. This science also focuses on Monitoring, Reporting and Verification (MRV) of various emissions of gases such as: Volatile particulate matter (vPM) and non-volatile particulate matter (nvPM), noise and heat from fuel combustion in aircraft engines for all international and domestic flights as well as ground-based operational processes. In addition to studying and developing appropriate mechanisms to solve problems and mitigate the contribution of the air transport industry to global warming and adaptation; This is done through improvements in operational procedures, environmentally friendly technologies, sustainable aviation fuel in addition to research and developments. This science also focuses on maintaining the quality of local air, the treatment of solid waste and sewage water from all aviation and airport-related activities, and the extent to which they affect the environment, the surrounding communities, in addition to employees and passengers in the airport and related facilities.
