2022年11月1日，《国际防止船舶造成污染公约》（MARPOL）附则VI修正案正式生效，该修正案要求船舶在短期内提高能源效率，从而减少温室气体排放。根据规定，自2023年1月1日起，所有船舶将被强制要求计算其达到的现有船舶能效指数(EEXI)，以衡量能源效率。同时，船舶还需收集数据，报告其年度营运碳强度指标(CII)及评级。这一最新的修正案是在2018年国际海事组织（IMO）船舶温室气体减排初期战略的框架下制定，IMO成员国目前也在积极参与对该战略的修订，以期在2023年年中通过修订后的战略。

Amendments to the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI entered into force on November 1, 2022. These technical and operational amendments require ships to improve their energy efficiency in the short term and thereby reduce their greenhouse gas emissions. From January 1, 2023, it will be mandatory for all ships to calculate their attained Energy Efficiency Existing Ship Index (EEXI) to measure their energy efficiency and to initiate the collection of data for the reporting of their annual operational carbon intensity indicator (CII) and CII rating. These latest amendments developed under the framework of the Initial IMO Strategy on Reduction of GHG Emissions from Ships agreed in 2018. IMO Member States are currently actively engaged in the process of revising the Initial IMO Strategy on Reduction of GHG Emissions from Ships with a view to adoption of a revised Strategy in mid-2023.

EEXI（Energy Efficiency Existing Ship Index）P.n 现有船舶能效指数

Tips：现有船舶能效指数(EEXI)是对现有船舶单位货物载重吨和单位英里CO2排放量的计算，适用于《MARPOL公约》附则VI规定的所有总吨超过400的船舶，钻井平台、非动力船舶和部分破冰船除外。船舶的EEXI需要通过计算确定，并与船型的强制要求限值进行比较。如果计算所得EEXI高于强制要求，则需采取措施确保其符合规定。EEXI技术文件必须及时提交至船级社，并在取得船级社批准后随船携带。
