Meeting the Challenge of 0 carbon emission at 2050


EEXI(Energy Efficiency Existing Ship Index)是国际海事组织(IMO)为应对航运业的温室气体排放而创建的对现有船舶能效进行测量的指标。EEXI根据船舶的各项技术和操作特征来确定,包括发动机功率、速度、货物容量以及设计和任何已进行的改装或升级。







Meeting the Challenge of 0 carbon emission at 2050

The EEXI, or Energy Efficiency Existing Ship Index, is a measurement of the energy efficiency of existing ships that was created by the International Maritime Organization (IMO) to combat greenhouse gas emissions from the shipping industry.

The EEXI is determined based on various technical and operational characteristics of a ship, including its engine power, speed, and cargo capacity, as well as its design and any modifications or upgrades it may have undergone.

The main objective of the EEXI is to encourage ship owners to improve the energy efficiency of their vessels and thereby reduce their carbon footprint. A higher EEXI rating indicates greater energy efficiency and a more eco-friendly vessel.

Starting from January 1st 2023, all ships over 400 gross tonnage are required to meet a minimum EEXI rating to comply with new IMO regulations. Ships that do not meet the rating requirement must adopt energy efficiency measures or face penalties. The EEXI file must be in place for audit with the first scheduled survey of the ship in 2023. The absence of such technical file will be considered as violations and will lead shipowners to tremendous consequential costs.

These regulations are predicted to have a significant impact on the shipping industry, as owners and operators will need to invest in energy-efficient technologies and practices to meet the new standards.

Overall, the EEXI is a critical tool in promoting sustainability in the shipping industry and reducing its negative impact on the environment. As global concerns about environmental protection and sustainability grow, the EEXI will continue to play an important role in ensuring that the shipping industry takes appropriate measures to reduce its carbon footprint.

International Register of Shipping (INTLREG) is an International Independent Classification Society that since 1993 is well established in Chinese market. With the support of our global resources, our team in China is continuously providing effective and valuable assistance to Chinese ship owners, ship management companies, and other organizations in achieving the goal of zero carbon emissions by 2050.
