With reference to MEPC 76, the combined technical and operational approaches to improve energy efficiency of ships and GHG reduction measures, explain the below mentioned new requirements.

Part (a)

Energy Efficiency Existing Ship Index (EEXI)

Part (b)

Carbon Intensity Indicator (CII) and CII rating

Part (c)

Enhanced SEEMP

(Refer to the detailed answers for 679e2d8010fccdd99a8a5c3e and 679d0e21bc2c89ff76a29929.)

Part (a)

EEXI: The Energy Efficiency Existing Ship Index is a technical measure of the energy efficiency of existing ships (in g CO2 per tonne-nautical mile), calculated from the ship's design (installed power, fuel consumption, capacity, speed). From 1 January 2023, existing ships must meet a "required EEXI" (a reference line with reduction targets); a ship whose attained EEXI exceeds the required value must install energy-saving technology (e.g. engine power limitation, propulsion power limitation, waste-heat recovery, or other measures) to comply. The attained EEXI is verified and recorded in the International Energy Efficiency Certificate (IEEC). It is a technical (design-based) measure to improve the efficiency of the existing fleet.

Part (b)

CII and CII rating: The Carbon Intensity Indicator is an operational measure of the ship's annual carbon intensity, calculated as g CO2 per capacity-nautical mile (gCO2/(dwt.nm) or per gross ton-m for passenger ships), based on the fuel consumed and the distance/capacity in a year. From 1 January 2023, ships must calculate their attained CII annually and compare it with a "required CII" (a reference/improvement curve), obtaining a rating A to E (A best). Ships with a poor rating (E, or D for 3 consecutive years) must develop and implement a corrective action plan (in the SEEMP Part III) to improve. The CII is reported and verified through the IMO data collection system, driving operational efficiency and GHG reduction.

Part (c)

Enhanced SEEMP: The SEEMP (Ship Energy Efficiency Management Plan) is enhanced under the CII regime. The SEEMP Part III sets the required and attained CII, the improvement trajectory, the data collection and reporting, and the corrective/improvement actions; it must be updated annually with the attained CII and is verified/reported to the IMO. The enhanced SEEMP requires the ship to have a plan of practical measures to achieve its required CII and to improve its rating each year, and to take corrective action if the rating is poor. It is part of the combined technical (EEXI) and operational (CII/SEEMP) approach to reduce GHG emissions from shipping.
