Overview

This Guide has been developed based on INTERTANKO’s Best Practice on Tanker Emissions and Energy Efficiency (INTERTANKO Best Practice).

The Guide provides a template for developing a Company Energy Efficiency Management Plan (sections 2 and 7) and goes into detail regarding the measures that may be implemented on board to improve energy efficiency within a tanker fleet (section 3 to 6).
