DNV has launched the EEXI Calculator – a new digital self-service tool to support customers in ensuring their compliance with the upcoming Energy Efficiency Existing Ship Index (EEXI), a medium-term component of the IMO roadmap towards reducing global shipping’s carbon intensity over the next decade, due to take effect in 2023. The aim of the EEXI is to assess the energy efficiency of existing ships, focusing solely on their design. It determines the standardized CO2 emissions related to a vessel’s installed engine power, transport capacity, speed, and degree of energy efficiency.
