The International Maritime Organization is being encouraged to block countries from being allowed to delay implementation of a planned ban on the use and transport of heavy fuel oil (HFO) in the Arctic regions until 2029.

Responding to reports that Canada and Russia have asked the IMO for a five-year delay to implement the planned ban, which is due to come into force in 2024, the Clean Arctic Alliance lead advisor Sian Prior made a direct demand to the United Nations body.
