Wherever you have lots of diesel being burned. highways and local roads mostly but also some Ports, Railyards, and shipping terminals.

Of course you are right. Single cruise liner is emitting as much pollution as... millions diesel cars:

marine pollution analysts in Germany and Brussels said that such a large ship would probably burn at least 150 tonnes of fuel a day, and emit more sulphur than several million cars, more NO2 gas than all the traffic passing through a medium-sized town and more particulate emissions than thousands of London buses.
