Databases

One of the main tasks of ICAO's Committee on Aviation Environmental Protection (CAEP) is to identify and carry out analyses of the future trends and various options available to limit or reduce the current and future impact of international civil aviation noise and emissions. The aim of these analyses is to assess the technical feasibility, the economic reasonableness, and the environmental benefits, as well as the interdependencies of the options considered. In doing so, CAEP has relied on the use of a variety of computer-based models and databases offered by Member States and international organizations that participate in CAEP.

Contributing Databases

As the need for a better-informed policy-making process grows, CAEP's modelling requirements in terms of coverage (i.e. noise, emissions, costs and benefits, etc.) and accuracy increase. Each model and database has its strengths and weaknesses, and using multiple models provided CAEP with insight into the sensitivity of the results. Going forward, the model evaluation process has established a framework for the future evaluation of new models and updates to the existing tools.
