Carbon Intensity Indicator (CII) Video Series

The Global Industry Alliance to Support Low Carbon Shipping (Low Carbon GIA) and Arcsilea Ltd. have developed a series of videos on the latest major amendments to MARPOL Annex VI, adopted by the IMO, namely the Energy Efficiency eXisting Ship Index (EEXI) and the Carbon Intensity Indicator (CII).

This 5 part video series on the Carbon Intensity Indicator (CII), a new regulation that came into effect 1 January 2023.  The series aims to provide an overview of CII as well as to raise awareness and increase understanding by providing explainers of what is in the regulation as well as how to apply, and where to look for more information about it.

You can find out more about the EEXI and CII regulations on the IMO Frequently Asked questions page.

For more information on EEXI please see our EEXI Video Series.
