London Greek shipowners have added their voices to criticisms of the “simplistic” Carbon Intensity Indicator as a short-term tool to decarbonise the industry.

The International Maritime Organization’s new operational tool seeks to rank and target the worst emitting vessels but sections of the industry have criticised it as unfair, lacking teeth and with damaging unintended consequences.

The measure “seems to have no respect from either charterers or shipowners,” said the chairman of the Greek Shipping Cooperation Committee, Haralambos Fafalios.
