The 9th Conference is being held on a cruiser, a beautiful example of a complex integrated energy, water, environment, food, transport system. There is a perception that cruisers are not sustainable, and there are certainly many things that could be improved by the research of our participants, but are cruisers really so unsustainable? Cruisers use as much fuel as 5000 cars doing the same distance (http://goo.gl/maps/JaKnO), slightly more than jet planes (4.8 l/100 passenger km at 80% load), but they will deliver not only transport, but also accommodation, catering and entertainment to its 4000 passengers and jobs to its 1400 staff. The panel will discuss these issues. What is more sustainable, all in one, or travelling by car doing the same trip, staying in local hotels, eating in local restaurants? Also, how cruiser and shipping in general can be made more sustainable?
This contribution analyses and compares the environmental impact of different travel options, such as by cruise and by car with and without combination of ferry. As the environmental impact the Greenhouse gas (GHG) footprint from life cycle perspective is selected. Several scenarios are considered in terms of the route, car occupancy rate, and type of car – luxury and average (non-luxury) cars. The comparative basis of luxury and entertainment is considered as much as possible. An example of travel trip on a luxury Mediterranean cruise is investigated, and compared with the trip to the same locations (Venice, Bari, Katakolon, Izmir, Istanbul, Dubrovnik, Venice) by car and by combination of car and ferry. The results show that the car occupancy and type of car significantly affect the GHG footprint. If luxury, entertainment, accommodation and food are fully included, the cruise is a clear winner.
