Carbon Emissions from Cruise Ships: A Case Study in The Ports of Souda and Heraklion, Crete, Greece

/in /by

Modern cruise ships consume considerable amounts of energy and emit large quantities of greenhouse gases during their luxury trips compared with other types of tourism. During the last years the ports of Souda and Heraklion, Crete host a large number of cruise vessels. The carbon emissions of cruise ships during their mooring in the abovementioned ports have been estimated using data from the existing literature. The alternative fuels which can be used in these cruise ships decreasing their emissions have been also examined. The carbon emissions from the mooring of cruise vessels in Souda port in 2024 have estimated at 16,505 tnCO2 while in Heraklion port at 30,537 tnCO2. Cruise ships face mounting pressure to reduce their environmental impact and alternative fuels are central to this transformation. Several alternative fuels including LNG, biofuels, hydrogen, ammonia, methanol, and electricity can be used in cruise ships substituting the fossil fuels currently used like heavy fuel oil. The ports of Souda and Heraklion should develop the necessary infrastructure to provide alternative fuels and on-shore electricity to cruise vessels approaching these ports in the near future. The current study could be useful to ports’ authorities in Crete, to cruising companies as well as to the stakeholders of Cretan ports.

/in /by

The concept of degrowth has been developed recently as an alternative paradigm to continuous and unlimited growth which prevails nowadays. The degrowth of tourism industry has been proposed in overcrowded tourism destinations balancing the satisfaction of tourists and local residents with the sustainability of the natural ecosystems. The island of Crete, Greece is located in eastern Mediterranean basin hosting an increasing number of visitors every year. The tourism industry in the island is well developed having a high economic impact. The prosperous tourism industry in Crete has surpassed the carrying capacity of the island threatening its fragile ecosystems causing phenomena of overtourism with undesired and harmful impacts in the local societies. The degrowth of the local tourism industry can be conceived as an alternative paradigm of the current growth model of tourism which threatens its long-term sustainability. It rejects the current model of continuous and unlimited growth of tourism promoting the values of locality, development of small-scale enterprises, quality of life, environmental sustainability, reduction of carbon emissions, decommodification of tourism activities and smaller production and consumption. The adoption of tourism degrowth in Crete requires the mobilization and the active participation of the multiple stakeholders of the tourism industry in the island while it promotes their long-term interests which are currently threatened by overtourism, climate crisis and overconsumption of the limited natural resources.
