ENVISA supports EUROCONTROL in its activities for the ICAO Committee on Aviation Environmental Protection (CAEP) Modelling and Database Task Force (MODTF). The objective is to help set realistic and achievable environmental goals in terms of reducing aircraft noise and greenhouse gas emissions and improving local air quality. This includes assessing the benefits of new stringency policies (e.g. on engine NO_x emissions) and comparing and validating the models available worldwide to carry out impact assessments.

In the fields of greenhouse gas emissions ENVISA:

• develops global fleet and flight movement forecasts through 2035 with and without new stringency options
• assesses current and future global emissions with EUROCONTROL’s Advanced Emission Model (AEM)
• produces emission evolution trends by country
• compares and validates fuel burn models with data from airlines (Flight Data Recorder).

At the same time, ENVISA participates in the CAEP evaluation process of the Local Air Quality tools such as EUROCONTROL's ALAQS-AV model by running emission and dispersion simulations at a mock-up airport and comparing outputs with other European and US models.
