Denmark to ban one of the fuel types for Arctic ships

07 february 2024

The Danish government plans to ban the use of heavy oil as fuel for ships in the Arctic from July 1, RIA Novosti reports, citing the kingdom's Environment Minister Magnus Heunike.

According to him, if an oil leak occurs from the ship, it will create a great risk to the marine environment, which is especially dangerous for the Arctic, where the marine environment and coastal ecosystems are particularly vulnerable.

"Therefore, we are stopping the use or transportation of heavy oil on ships as fuel when they sail in the Arctic," Heunike said.

The ban will have to partially limit ocean and air pollution from oil leaks, since heavy oil, compared with lighter fuels, "emits more particles, including so-called black carbon, CO2 and more sulfur."

The ban will come into force on July 1, 2024, but during the transition period, until July 1, 2029, a number of exceptions will be made.
