The impact of slow steaming on reducing CO2 emissions in the Mediterranean Sea

One of the short-term operational measures for reducing CO2 emissions from ships at sea is sailing at reduced speed, i.e. slow steaming. In this study, the benefits of slow steaming are studied using the example of a container ship on a typical sailing route passing through the Mediterranean Sea. Th...
