Note: For the calculation of the volume of SOx, NOx and PM the Company uses conversion factors laid down by Carnival Corporation for the evaluation of ship emissions. There are no GHG emissions standard metrics in the cruise line industry.
Electricity consumption TOE (Tons of Oil Equivalent) 892.76 937.22 525.86 With the aim of guaranteeing a system of control and management of the level of impact generated by each ship (from operating the diesel-electric and diesel power plants) the parent company has implemented measures based on existing
International Maritime Organization (IMO) regulations, including the voluntary introduction of a Ship Energy Efficiency Operational Indicator (EEOI) as a monitoring tool for managing passenger ship efficiency performance over time.
The Company measures and reports the ship fuel consumption rate in terms of grams of fuel per Available Lower Berth Kilometer (ALB-Km). It is pointed out that the SOx indicator also takes into account the sulfur content of the fuel; this value
Energy consumption in GJ * is obtained from the bunker delivery notes issued to the ship upon each delivery of fuel.
