Data collection framework for enhanced carbon intensity indicator (CII) in the oil tankers

The Canadian Journal of Chemical Engineering, Volume 103, Issue 1, Page 170-187, January 2025.
Abstract The International Maritime Organization (IMO) aims to reduce greenhouse gas (GHG) emissions by 40% by 2030 compared with 2008. The carbon intensity indicator (CII) calculates the annual reduction factor required to continuously improve a ship's operational carbon intensity at a specific rating level.
