MEPC 83’s agreement on decarbonization, slated for adoption in October 2025 and entry into force by 2027, will apply to large ocean-going ships that account for roughly 85% of international shipping’s CO2 output. This sweeping coverage ensures that thousands of ships including container liners, bulk carriers, and tankers, will face consistent global rules on emissions. It establishes the first-ever global decarbonization rules for an entire industry. Those who act with urgency and foresight can help steer the global maritime industry into a new era of sustainability – and secure their place at the forefront of the zero-carbon shipping economy that lies on the horizon.
