Greenhouse gas emissions reduction

In addition to regulations on new ships to meet an Energy Efficiency Design Index (EEDI), the International Maritime Organization (IMO) has further adopted amendments to MARPOL Annex VI to reduce greenhouse gas emissions from ships in operation.
 
The new requirements are limiting the use of power of ships in operations – Energy Efficiency Existing Ship Index (EEXI) – and define certain requested carbon intensity levels based on which ships’ efficiency is rated via a Carbon Intensity Index (CII).
 
INTERTANKO has provided advice and guidance to Members to assist them in EEXI compliance and continues to provide assistance to Members on the complex application of the CII requirement so they can ensure a correct calculation of the CII attained value and of the CII rating. The IMO is currently considering the possible introduction of Phase 4 level limits.
