Environmental lobby groups have criticised the International Maritime Organization’s decarbonisation strategy as inadequate, despite more countries committing to zero emissions by 2050 at a key environmental gathering.

Last week’s Marine Environmental Protection Committee (MEPC) meeting saw momentum growing behind proposals to revise the IMO’s initial strategy and aim to decarbonise shipping by 2050.

IMO secretary general Kitack Lim said he was “encouraged by the commitment to finalise the revision of the initial strategy”.
