The U.N. May Make Ocean Cruises More Expensive
Cruise companies are spending six-figure sums on consultants to interpret the IMO's Net Zero Framework. The framework was approved in April 2025 but postponed until October after U.S.-led bloc pressure, with a carbon-tax mechanism planned to begin around 2028 and significant costs for dual-fuel ship systems.
Why It Matters
The potential regulatory change could raise costs for cruise and other shipping, affecting shipbuilding, fuel strategies, and global competitiveness, especially for the United States.
