A ban on HFO in the Arctic was considered in 2013 during the deliberations on the IMO Polar Code. However, while some member states were supportive, no consensus was reached.
In April 2018, an agreement was reached to develop a ban, and now in 2019, the Arctic HFO ban is on its way. Specifically, during 2019 a technical elaboration of measures will take place in PPR 6 and MEPC 74, to move the Arctic HFO ban one step closer to reality.
The actual adoption of the ban is expected to take place on 2021, with the industry making its decision on what fuels it will use during 2022.
At last, the ban will apply in 2023.
