The ATTICA consortium offers to provide the European community with a coherent series of assessments of the impact of transport emissions on climate change and ozone depletion. Three assessments will cover the emissions of single transport sectors, viz. of aviation, shipping, and road and rail traffic. Another assessment deals with metrics that allow describing, quantifying, and comparing in a fair way the effects of the transport emissions in the atmosphere. Finally, a synthesis of the foregoing assessments will be written that will provide the overview of the impacts of the emissions of all transport sectors on climate change and the ozone layer.

For the first time, different modes of transport will be consistently assessed. The consistent assessment allows the interested citizen to estimate in principle their own contribution to environmental problems and to compare it to that of others. Apart from policy and decision makers, the synthesis assessment will help journalists, teachers, and others, to digest the results and to present them in public media, in schools and universities, ensuring wide spread of the results. The assessments and the synthesis report will inform the EU in developing its policy and will strengthen its position in international climate conventions and other international agreements.
