Maritime shipments are responsible for the shipping of 90% of cargo transports in terms of volume globally. Although ocean container shipment is the preferred shipping mode in terms of environmental footprint, sea transport is still responsible for 808,5 MtCO2e/year accounting for 21% of the total contribute of logistics carbon emission. The European Union acknowledged the contribution of the transport sector to climate change and included maritime shipments to its cap-and-trade Emission Trading System. Therefore, methodologies to reduce the environmental impact of maritime shipping are required. This needs to be achieved while ensuring that the costs of ocean container shipments remain competitive compared to alternative transportation modes that offer quicker delivery times but have greater environmental consequences.
