June 7 (UPI) -- Cruise passengers in Barcelona will have to pay more tourist taxes to fight pollution caused by massive ships docking in the Spanish port city.

The Catalan government that oversees Barcelona has not yet announced how much the new tax will cost.

"We expect to be able to present, in the coming weeks, the government's proposal to regulate emissions in the port areas of Catalonia, and we will be delighted to be able to share with Barcelona town hall the work carried out and the formula for this tax," said Teresa Jordan, the Catalonian minister for climate action.

The new tax will be added to the Catalonia government's existing tourist tax for Barcelona's cruise passengers, which is 3 euros for a stay of more than 12 hours, 1 euro for less than 12 hours and a daily surcharge of 1.75 euros.
