To aid the implementation of Europe’ policies, a model based assessment is required. Whilst it is unlikely that source emissions regulation policies will be implemented solely within the EU, it is possible that other measures – air quality standards, international agreements, technology insertion, economic measures, land use planning will be implemented only within the European Air Transport System only, at least in the beginning.

Europe’s policies require a model-based assessment. Whilst it is unlikely that source emission regulation will be implemented only within the EU, it is feasible that other measures – such as operational measures, air quality standards, international agreements, technology insertion, economic measures, land use planning – may be implemented within the European air transport system only, at least in the beginning. Emissions trading is a topical example. There is a high probability in the future that there will be further policies on the European level to implement a sustainable aviation policy.

For a well balanced sustainable aviation policy it is crucial to be able to assess, in advance, the potential results of any measure or instrument. There are already plenty of existing models providing singular results. However, as a consequence of the noise/emissions/cost interdependency of policy measures, the outcome of these models is no longer persuasive. An integration of all competencies on the European level will lead to an integrated approach. The integration platform to be created shall be capable of engaging different models, even if they are aimed at the same modelling task, in order to identify best-fit strategies and the validation of different modelling tools.



A large set of policy issues in the field of aviation and environment is discussed in ICAO/CAEP and on European level. Currently, the most urgent requirements are the capability of modelling noise, NOx stringencies and greenhouse gases in relation to the Kyoto protocol as well as related agreements together with their respective effects. Careful analysis of the complex interdependencies between air transport activities and environmental or economic effects is needed for the assessment of policies and guidance on a political level.

TEAM_Play will create a modelling framework to combine and advance European modelling capabilities in order to support the European perspective in the international policy arena.

TEAM_Play deals with interdependencies and trade-offs between noise, gas emissions, environmental and economic impacts of the air transport sector. The objective of TEAM_Play is to enhance the European modelling capabilities required for policy assessment. These capabilities will be strengthened by creating a common infrastructure allowing for the connection of existing European models.



The main objective of the TEAM_Play project is to set up an effective and efficiently working Tool Suite which should provide the European policy makers community with powerful tools to perform adequate policy assessment studies within ICAO-CAEP and on European, national and local levels.

European models are already represented in the list of models submitted to CAEP. However, there is no common approach by which the models can collaborate to produce a consistent forecast for noise, LAQ, GHGs and an assessment of the economic impacts of any given measure as well as the respective interdependencies. Currently, the engagement of these European models in CAEP is wholly dependent upon US supplied input data.

Relevant scientific, technical and socio-economic objectives

The existence of a CAEP-endorsed European modelling input would allow for:

  • An increase in the number and type of policy measures modelled
  • The use of alternative future scenarios and fleets
  • The modelling of European style CNS/ATM improvements
  • The modelling of emissions trading and charging scenarios
  • An assessment of the effect of non-US assumptions


Main socio-economic objectives:

  • Strengthening of the European modelling industry by creating a framework which allows existing and new models to be integrated for an assessment of the diverse effects of aviation policies
  • Ensuring sustainable growth of air transportation with regard to environmental, social and economic issues
