Barcelona’s cruise-ship port is to close two of its terminals, as part of efforts to fight the city’s overtourism problem.

The closure, which will bring the number of operational terminals down to to five when it takes effect next year, is part of an agreement with Barcelona’s city council, announced in a statement from the council Friday.

The agreement also provides funding for a study to evaluate how cruise-ship passengers move around the city, which the council says is a first step in developing sustainable mobility plan.

In addition, the agreement will involve the modernization of port infrastructure to make cruise operations more sustainable – for example, by allowing ships to connect to a green onshore power supply while they are docked, meaning their engines can be switched off, cutting emissions.

Overall, the plan will involve 185 million euros ($216 million) in public-private investment, according to the council statement.
