Several parties are joining Japan in their proposal to regulate the carbon intensity of existing ships through use of an Energy Efficiency Existing Ship Index (EEXI), much like the Energy Efficiency Design Index (EEDI) which is mandatory for new ships. The proposal offers a simplified way to comply by using estimated speed/power curves and power limitation. Together with Greece, Japan, Norway, Panama, The United Arabic Emirates, ICS, INTERTANKO and RINA, BIMCO is proposing a comprehensive package of amendments to MARPOL Annex VI and associated guidelines for calculation of EEXI and application of Engine or Shaft Power Limitation. The package will require existing ships to comply with the energy efficiency limits of new ships at the time of adoption.
