The International Chamber of Shipping (ICS) has submitted a proposal to the International Maritime Organization for a levy on carbon emissions to fund the adoption of zero-carbon technologies and fuel.
The levy would be applied globally to all ships over 5,000 gt.
The ICS did not indicate at this stage how much shipowners would be expected to pay.
The money raised would be put in a climate fund run by the IMO to establish bunkering infrastructure for alternative fuels, including ammonia and hydrogen.
