Greece is officially backing the IMO drive to reduce shipping’s carbon footprint through an elaborate formula that measures vessels’ energy efficiency.

However, some in the country’s shipping community are unimpressed: they believe it fails to reduce emissions and merely shifts power from owners to bankers, shipyards and charterers.

Their gripe centres on the Energy Efficiency Existing Ship Index (EEXI), which the IMO plans to use as a yardstick for the amount of greenhouse gases (GHGs) ships built before 2013 emit into the atmosphere.
