Low-sulfur bunker fuel sales have decreased since 2020

When the International Maritime Organization's lower marine sulfur limit known as IMO 2020 took effect in January 2020, commercial shippers pivoted sharply to fueling their vessels with low-sulfur fuel oil (LSFO). In the years since, high-sulfur fuel oil has reclaimed some market share, as a growing number of commercial vessels install sulfur scrubbers that allow operators to use the heavier, cheaper fuel oils while complying with the new sulfur emission limits.
