The Union Internal Navigation Italian (UNII) Based in Marghera-Venice is the national association that works to strengthen the coordination and development of inland and fluvio-maritime in Italy, both for tourism a and for freight. The UNII is an Association no-profit composed of public representatives such as regions, municipalities, counties, chambers of commerce, port companies, consortia of industrial development, and Private or business organizations, which operate or have interests in the field of inland. UNII was constitued in 1919 and has been recognized legal personality with DM n. 1866 of 19 June 1992. The activity of association follows the guidelines of statute and regulation. The primary aim of UNII is the development of IWT commercial and tourist. It coincides with a strategic objective of transport planned at an European level (White Paper on transport – Community guidelines for the development of a trans-European transport network), both nationally (General Transport Plan), or the modal reorganization of traffic, to be implemented by transferring the movement of people and goods from road to rail, cabotage and inland. The inland waterway Italian network has the ability to connect – through the Venetian coastline restored and fully navigable from Venice to Trieste – with the navigation system fluvial-maritime, with all harbours in the Mediterranean and the waterway network of rivers Rhone, Danube and Volga. For these reasons UNII is associated with the European Federation of Inland Ports, Based in Brussels, where in 2011 the European Commission has included all the waterway system from Trieste to Milan Ten-T networks in Europe. The concentration of the Road traffic – In Italy the share of freight traffic on the internal rubber exceeds 80% of the total – it involves the inefficiency of the whole transport system and a strong negative impact on environment (See fee Co2 from 2020 for our country) and security. It is measurable through the external costs of transport, which is so-called because those operating do not fall on the user, but on the entire community. The external costs of inland navigation for moving goods are a small fraction compared to that for haulage. Consequently, the transfer of freight from road to water results a considerable saving in terms of external costs and, therefore, a huge benefit for the community. A study carried by UNII has shown that the transfer of traffic from road to waterways, feasible through the construction of the waterway system Padano Veneto (or at least of its most important parts), would allow a saving of about EUR 103 million a year in terms of external costs. A real benefit for the community. This savings is significantly higher compared to the cost of the implementation of the system
