In 2008 the U.N. International Maritime Organisation set up new rules for sulphurous content in maritime fuel. That decision will also have consequences for shipping and trade in, inter alias, the Baltic Sea. From the 1st of July 2010, ships sailing in the Baltic Sea are allowed to have only 1, 5 % sulphurous content in the fuel of the ships and only 0, 1 % in 2015-01-01. Is this a threat to the tourism industry? Will there be fewer cruising ships in the Baltic Sea? Will the ferry traffic between the harbours in the Baltic Sea decrease due to higher fuel price, because of less sulphurous content in the fuel?
