IMO Net-Zero Framework Expected in 2026: Carbon Pricing and Fuel Standards Ahead
The International Maritime Organization is set to finalize its "basket of measures" including a global fuel standard and carbon pricing mechanism. Entry into force is projected for mid-2027.

What Happened
The International Maritime Organization continues work toward finalizing mid-term measures under its 2023 Revised GHG Strategy, with adoption now expected in 2026.
IMO 2023 Revised GHG Strategy targets:
- Net-zero GHG emissions: By or around 2050
- 2030 checkpoint: At least 20% reduction (striving for 30%) vs 2008 baseline
- 2040 checkpoint: At least 70% reduction (striving for 80%)
- 2030 fuel target: Zero/near-zero emission technologies to comprise 5-10% of energy used
Proposed "basket of measures":
1. Technical element: Goal-based marine fuel standard regulating GHG intensity reduction
2. Economic element: Maritime GHG emissions pricing (levy, feebate, or cap-and-trade)
Existing measures under review (by January 1, 2026):
- Energy Efficiency Existing Ship Index (EEXI)
- Carbon Intensity Indicator (CII)
- Review considering: Increased stringency, CO2e scope expansion, enforcement strengthening

Why It Matters
The mid-term measures represent the most significant regulatory development in maritime history. A global carbon price would fundamentally alter the economics of shipping, making alternative fuels more competitive and penalizing high-emission operations.
The strategy adopts a "well-to-wake" lifecycle approach, meaning emissions from fuel production and transport count—not just combustion. This benefits genuinely green fuels over gray alternatives.
CII compliance has created contractual challenges, as charterer decisions affect owner ratings. The BIMCO CII Operations Clause provides a template, but operational disputes continue.

What It Affects
Costs: Carbon pricing will increase voyage costs, with magnitude depending on final mechanism design.
Operations: CII ratings require voyage optimization and may limit commercial flexibility.
Risk: Ships with poor efficiency ratings face restrictions on commercial opportunities.
Timelines: Mid-2027 entry into force gives limited time for fleet and operational adjustments.
