Amidst the IMO sustainable fuel regulation highs and lows there are other parts of the maritime regulatory environment that may warrant a closer look.For roughly a century, maritime relied on liquid fossil fuels. Meanwhile, it took over half a century for regulations to start to deal with the negative effects of liquid fossil fuels and to effectively deal with maritime fossil fuel disasters.The star player in this effort was OPA90, which, once implemented, massively reduced the…

A new insight brief by the UCL Shipping and Oceans Research Group for the Getting to Zero coalition, titled "Uncertainty at the IMO: Three scenarios and their consequences for shipping’s transition”, concludes that of those options only the ‘as is’ (Net Zero Framework as agreed in principle in April 2025) has the potential to provide a credible, stable demand signal and revenue stream to support early and mass-market uptake of scalable zero-emission fuels.Weaker alternatives risk delaying scalable zero-emission fuel availability into the 2040s…

The livestock carrier Spiridon II has unloaded cattle in the Libyan city of Benghazi after being stranded off the Turkish coast for more than a month after a month-long voyage from Uruguay with nearly 3,000 cattle on board.The Spiridon II is now back at sea.It is unclear what happened to the dead animals and sewage onboard. Dozens of animals had already died, and many calves had been born, lost, or perished. The dead animals and excrement cannot legally be disposed of in the Mediterranean Sea due to MARPOL regulations.

The recent rejection of around 2,900 dairy cattle on the Spiridon II raises animal welfare and pollution concerns when, after a long sea voyage, the laden vessel has again had to return to sea.The 52-year-old livestock carrier has left Turkey after its cargo was rejected by local authorities. Court transcripts translated by Animal Welfare Foundation indicate that 58 cows died in transit to Turkey, 140 cows had miscarriages in transit, 50 newborn calves were present on board, but another 90 are unaccounted for.Having departed from Montevideo…

The 52-year-old livestock carrier Spiridon II remains in quarantine off Turkey with around 20 crew and 2,853 cows onboard.Having departed from Montevideo (Uruguay) bound for Turkey on September 19 with 2,901 heifers, some of which may be pregnant, the Spiridon II is, over 50 days later, still unable to deliver the animals to shore.Veterinary authorities are refusing to allow them to disembark due to a controversy over ear tags that guarantee, among other things, the exact origin…

Heads of seven shipping associations have called for the IMO to adopt its Net-Zero Framework (NZF) at the crucial vote in October. Anything else would be a major setback for the green transition and risk leaving the industry with a complicated patchwork of regional climate regulations.Next week the 176 members of the IMO will convene in London to formally adopt the historic agreement on binding climate regulation of the shipping industry agreed upon in April.Danish Shipping along with six other shipping associations calls for the adoption of the IMO Net-Zero Framework.

The ocean takes center stage on World Maritime Day 2025, as the IMO celebrates how the industry is stepping up action to protect the ocean.This year’s World Maritime Day, observed globally on 25 September, focuses on the sector’s impact on the marine environment, and what it can do to reduce pollution, curb greenhouse gas emissions and prevent biodiversity loss.Secretary-General of the IMO Arsenio Dominguez said: “IMO has, for many decades, worked to strike the right balance to ensure that the shipping industry is not the problem but the solution.
