Environmental impact assessment is the process of identifying and evaluating the environmental impacts of projects as well as proposing ways of mitigating such impacts. The scope of such assessments, as they relate to air traffic management (ATM), is not only the impact on the environment of aircraft operations but also the impact of any mitigations to such environmental impacts on aircraft operations.
In support of the quantification part of the environmental impact assessment process, we at EUROCONTROL have developed and maintain three models: AEM for global fuel/emissions impact assessments, Open-ALAQS for detailed airport air quality assessments, and IMPACT for advanced fuel/emissions and noise impact assessments.
