The money collected would go into a climate fund that would be used to deploy bunkering infrastructure in ports around the world to supply cleaner fuels such as hydrogen and ammonia, according to the proposal.
'What shipping needs is a truly global market-based measure like this that will reduce the price gap between zero-carbon fuels and conventional fuels,' said ICS secretary general Guy Platten.
The proposal was submitted to the UN's shipping agency, the International Maritime Organization (IMO).
The IMO said all proposals were welcome and would be up for discussion later this year, adding that 'proposals on market-based measures (MBM) are in line with the initial IMO GHG (greenhouse gas) strategy.'
With about 90 per cent of world trade transported by sea, global shipping accounts for nearly three per cent of the world's CO2 emissions and the sector is under growing pressure to get cleaner.
