The International Maritime Organization (IMO) has implemented new regulations, effective from November 2022, to reduce greenhouse gas (GHG) emissions from ships. These regulations, known as the Carbon Intensity Indicator (CII) and Energy Efficiency Existing Ship Index (EEXI), aim to improve the energy efficiency of ships and reduce their carbon intensity. In this blog post, we will delve deeper into these regulations, their significance, and discuss how Permaflow®, a fixed and non-invasive ultrasonic flow and heat meter, can help ship operators meet and exceed these requirements. For more detailed information regarding these regulations and how Permaflow® can help you comply with them, please drop us an email today.
Understanding the CII and EEXI Regulations:
The CII regulation and the EEXI regulation are crucial components of IMO’s commitment to reducing carbon intensity in the shipping industry. Let’s explore each regulation in detail:

Carbon Intensity Indicator (CII):
The CII regulation requires ships with a gross tonnage of 5,000 and above to calculate their annual operational carbon intensity and obtain a CII rating. The CII rating reflects the ship’s performance in terms of reducing GHG emissions relative to the amount of cargo carried over the distance traveled. Ships will be rated on a scale from A to E, with A being the best performance level and E indicating inferior performance. Ship operators need to report their CII rating annually and strive for continuous improvement.
Energy Efficiency Existing Ship Index (EEXI):
The EEXI regulation applies to ships with a gross tonnage of 400 and above. It measures a ship’s energy efficiency compared to a baseline and ensures that it meets the minimum energy efficiency standards. The attained Energy Efficiency Existing Ship Index (EEXI) is calculated for each ship, taking into account factors such as ship type and size categories. The calculated attained EEXI value must be below the required EEXI to comply with the regulation.
