A single river barge can carry 40 times the load of a truck. CO2 emissions per ton cargo are up to four times lower for barges than for trucks. And transportation costs are up to six times lower. Despite the obvious benefits in terms of costs and environment, inland waterway transport in the EU accounts for only about 7 % of cargo transport. After some decades of very little development in the Baltic Sea region, inland shipping has gained momentum lately. Baltic Sea region countries are now catching up and making their joint voice heard in European transport politics – in the project EMMA.
