If we count all economic activities that depend on the sea, then the EU's blue economy represents 5.4 million jobs and a gross added value of just under €500 billion per year. In all, 75% of Europe’s external trade and 37% of trade within the EU is seaborne. Much of this activity is concentrated around Europe's coasts, but not all. Some landlocked countries host very successful manufacturers of marine equipment.
