In spite of the central role transport has in modern society, they influence in negative way the environment, in a local and a global context, in different ways, producing different types of externalities that have to be reduced with numerous strategies. A lot of national governments are directing their choices about transports to evolve towards sustainable mobility. In literature there're numerous definitions of sustainable mobility. In this context, in recent years the attention towards the environmental protection carriage of dangerous good has grown. The carriage of dangerous goods and knowledge of linked risks has assumed particular relevance. The accidental events involving these products have spurred, in some cases , environmental damages on a vast scale. The regulations are principally about labelling, characteristics of containers and means of transport, procedures of loading an unloading, training and behaviour of drivers and conformity of ship's papers. Nevertheless, a frame to individuate an overall view of danger for this transport activity is missing. In particular, it's not considered the simultaneous presence of more shipments in the same infrastructure or the unbalanced use of the different transport mode. This kind of approach should concern the infrastructure's management or, in general, the authority which supervises the transport system planning . It would be necessary, in this context, a global assessment of transport activity with a systemic approach. In this context, to promote sustainable mobility and to prevent global warning it's necessary a knowledge of the quantities, kind and nature of dangerous goods carried. European Union, for this aim, has imposed on Member States the recording of information about types of dangerous goods carried to construct a complete description of flows of dangerous goods in European context. In Italy, the available sources of information, indicates that most of national dangerous goods is carried by road. This imbalance produces relevant quantities of externalities in terms of environmental and social costs for the community. The aim of this note is to evaluate the quantities of dangerous goods carried in different territorial contexts. To individuate correct strategies for prevention and/or protection of risk linked to these transport activities it is essential an in-depth study of dangerous goods carried. This aspect constitutes a fundamental element in the risk analysis about surfaces and itineraries crossed by dangerous goods. In particular with these analysis it's possible to identify the most critical point (for example crossing of urban zones, sensible environments as rivers, lakes, etc.). The evaluation of risks allows to individuate strategies to prevent global warning. In this note, starting from available sources, aggregate and disaggregate methodologies are used to obtaining an assessment of dangerous goods carried out on national and international level in some European countries (Italy, Spain, etc.). A comparison of carried quantities with different transport modalities is also presented.
