As an International Maritime Organization (IMO) ban on the use and carriage heavy fuel oil (HFO) by Arctic shipping came into force on July 1, the Clean Arctic Alliance called on IMO member states, particularly Arctic coastal countries, to implement the Arctic HFO ban and enforce it fully with immediate effect – without resorting to loopholes.
The Alliance is also calling on the IMO to extend the area covered by the ban to include all Arctic waters north of 60oN, and to enact regulation to reduce black carbon emissions from shipping, which would help reverse the impacts of climate warming in the Arctic, through the use of cleaner fuels and diesel particulate filters. Recent Arctic Council studies of ship activity in the Arctic have shown an increase of 37 percent between 2013 and 2023 and a 111 percent increase in total distance travelled over the same time period.
In recent days, an Irish vessel, the Arklow Wind, was fined by authorities in Svalbard for carrying heavy fuel oil. In Norwegian waters around the island archipelago of Svalbard the use and carriage of HFO has been banned since 2022, it has been forbidden to carry or use heavy fuel oil in territorial waters
The International Maritime Organization has already formally recognised that black carbon is the second largest source of ship climate warming, and it is responsible for around 20% of shipping’s climate impact (on a 20 year basis). Black carbon has a disproportionately high impact when released in and near the Arctic – when emitted from the exhausts of ships burning oil-based fuel and settles onto snow and ice, it accelerates melting and the loss of reflectivity – the albedo effect – which creates a feedback loop that further exacerbates local and global heating.
The prohibition on use and carriage of polluting heavy fuel oil was agreed by the IMO in June 2021, but received criticism for including significant loopholes allowing countries to grant waivers, and for shipping companies to make use of exemptions for many vessels – meaning that the ban will only reach full speed in 2029.
Estimated 74% of Arctic shipping unaffected
Until then, HFO will no longer be allowed to be used or carried for use while sailing in Arctic waters, unless a ship has a protected fuel tank or has been issued with a waiver by an Arctic coastal nation – this leaves around 74% of Arctic shipping unaffected by the ban. Recent Arctic Council studies of ship activity in the Arctic have shown an increase of 37 percent between 2013 and 2023 and a 111 percent increase in total distance travelled over the same time.
“Governments and NGOs fought long and hard to achieve the ban on the use and carriage of HFO in the Arctic – yet see that it will be half-implemented is quite simply not good enough”, said Dr Sian Prior, Lead Advisor to the Clean Arctic Alliance .”IMO Member States, especially Arctic coastal countries, must go farther than the IMO ban by implementing it in ways that truly protect the Arctic from HFO spills and black carbon emissions – and that means refusing to offer loopholes to the shipping industry”.
“In addition, by implementing strong HFO regulations, the IMO can significantly reduce the risk of HFO spills and also see co-benefits – reducing air pollution, and slowing down the impacts of climate warming on the Arctic”, said Mr. Prior. “Combining better fuel choices today with the use of existing technology, ships operating in the Arctic would see black carbon or soot (a component of particulate matter) emissions reductions of more than 90%. As black carbon remains in the atmosphere for only a short period of time, if all shipping in the Arctic used lighter distillate fuels and installed diesel particulate filters – existing technology long used in land transport to reduce diesel fuel emissions – we would see rapid removal of a massive threat to Arctic sea ice – which is crucial for balancing the climate and weather in the Arctic and further afield.”
“Today, July 1st is an incredible opportunity for the shipping industry to demonstrate that it is willing to embrace a cleaner future”, added Prior. Instead of hiding behind the use of exemptions, shipping companies can switch to readily available, relatively cleaner fuels such as diesel or distillate marine fuels (e.g. DMA, DMZ) or to alternative forms of propulsion and install diesel particulate filters.”
“The use of scrubbers must be avoided – they are an excuse to keep using HFO, while transferring air pollution into marine pollution and moving to gas fossil fuels such as LNG simply replaces one potent short-lived but high impact climate pollutant – black carbon – with another – methane. Use of diesel fuel along with the installation of particulate filters or precipitators, as prescribed for other forms of transport, can reduce emissions of black carbon by more than 90 percent quickly and be a solid first step on route to decarbonisation”, concluded Mr. Prior.
Meanwhile, activist groups have underlined the dramatic growth in the number of ships operating in the Arctic. And Russia, which is moving to expand Arctic shipping dramatically and start year-round transits, also has not accepted the ban or taken any steps to enact its provisions.
