Plans to develop a ban on heavy fuel oil (HFO) from Arctic shipping, along with an assessment of the impact of such a ban, were agreed during the International Maritime Organization's (IMO) Marine Environment Protection Committee (MEPC 72), which closed on Friday in London.

The meeting directed the Sub-Committee on Pollution Prevention and Response (PPR) to develop a ban on heavy fuel oil use and carriage for use by ships in the Arctic at its next session, in February 2019 (PPR6), "on the basis of an assessment of the impacts" and "on an appropriate timescale".

In addition to assessing the impact of a ban on communities and developing a ban on HFO use and carriage as fuel in the Arctic, PPR 6 will develop a definition of HFO taking into account regulation 43 of MARPOL Annex I (the Antarctic HFO ban) and prepare a set of guidelines on mitigation measures to reduce risks of use and carriage of HFO as fuel by ships in Arctic waters.

The latest development follows the agreement made in July 2017 for MEPC to consider the "development of measures to reduce risks of use and carriage of heavy fuel oil as fuel by ships in Arctic waters".

A strongly worded proposal to ban HFO as shipping fuel from Arctic waters was co-sponsored by Finland, Germany, Iceland, Netherlands, New Zealand, Norway, Sweden and the US.

The proposal for a ban, along with a proposal to assess the impact of such a ban on Arctic communities from Canada, was supported by Australia, Belgium, Czech Republic, Denmark, Estonia, France, Ireland, Japan, the League of Arab States, Poland, Portugal, Spain, Switzerland, and the UK.

The proposal text states: "A single HFO spill could have devastating and lasting effects on fragile Arctic marine and coastal environments. In addition, Arctic shipping is projected to continue to rise, thus increasing the risk of a spill. For these reasons, the ban on HFO should be implemented as soon as possible, and any delay in implementation of the HFO ban by eligible ships should be short-lived... The co-sponsors propose that the implementation date of the ban be set for no later than the end of 2021."

Dr Sian Prior, lead advisor to the Clean Arctic Alliance, a coalition of 18 non-governmental organisations working to end HFO use as marine fuel in Arctic waters, commented: "Thanks to inspired and motivated action taken by a number of IMO member states to move towards a ban on heavy fuel oil, Arctic communities and ecosystems will be protected from the threat of oil spills, and the impact of black carbon emissions.

"A ban is the simplest and most effective way to mitigate the risks of HFO - and now we're calling on the IMO to ensure that this ban will be in place by 2021. Any impact assessment must inform, but not delay progression towards an Arctic HFO ban, and member states must ensure that Arctic communities are not burdened with any costs associated with such a ban," she continued.

"With Denmark the sixth Arctic nation to back a ban on HFO from Arctic Shipping, the green alliance of Arctic nations have sent a clear message to the IMO," said Kare Press-Kristensen, senior advisor in the Danish Ecological Council. "With both the Danish government and the Danish shipping industry united to ban HFO, we hope to gain further international support for the ban from more nations and progressive parts of the shipping industry. Next step will be to engage Greenland further in planning and preparing for the ban."

Tor Christian Sletner, head of environment, research and innovation at the Norwegian Shipowners' Association, was cited as saying: "We know heavy fuel oil is very hard to pick up, we know that in this environment, with ice-infested waters, with darkness, with heavy cold, with long distances, accidents with a ship spilling heavy fuel oil in the water is very serious."
