Vessel vetting company RightShip has slammed the energy efficiency and carbon intensity measures being introduced by the International Maritime Organization (IMO) as "too slow" and unlikely to pave the way for technological improvements.

The world's biggest third-party maritime due diligence firm said the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) may be too slow to enforce carbon cuts as they only factor in operational considerations.
