Each topic below brings together, in a single place: an operational explanation, the regulatory reference, scope of application, procedure, practical example, real cases, common mistakes, PSC observations, operational tips, a checklist and FAQ — regulations verified as of July 2026.

### EEXI and Engine Power Limitation (EPL)

A technical index calculated only once, but that permanently constrains the maximum available power: the most common route to compliance is limiting the engine, not modifying it.

### CII (Carbon Intensity Indicator)

The annual A-E rating that in 2026 requires an 11% reduction versus 2019 — and that, unlike EEXI, must be recalculated every year against increasingly strict thresholds.

### SEEMP Part II and Part III

The plan that links data collection (Part II) to the improvement strategy (Part III): a deadline often treated as mere documentary compliance, with direct consequences for the CII rating.

### IMO Net-Zero Framework

Not just an update to CII/EEXI, but a structurally new economic mechanism: a fuel intensity standard combined with a price on excess emissions.

### Environmental Vetting and GHG Rating

The RightShip A-E rating is not a regulatory formality: since 2026 it has become a commercial requirement that can exclude a ship from major commodity trader nominations.

### Alternative Fuels and Operational Readiness

LNG, methanol, ammonia: every alternative fuel brings its own set of specific operational risks, governed by the IGF Code, which must be addressed before adoption, not after.

### EU ETS and FuelEU Maritime

Two distinct but linked European mechanisms: one puts a price on CO2 emitted in EU ports, the other requires a progressive reduction in the carbon intensity of the energy mix used on board.

### Ballast Water Management Convention In Depth

Beyond the record book: how PSC sampling, BWMS commissioning testing and Same Risk Area exemptions actually work — details many Companies underestimate.

### Biofouling Management

Fewer invasive species transferred, less hydrodynamic resistance, fewer emissions: biofouling management is one of the rare environmental topics where ecological and economic interest coincide almost perfectly.

### Underwater Radiated Noise (URN)

A still-voluntary topic that naturally converges with energy efficiency: the same measures that reduce emissions often also reduce underwater radiated noise.

### Onboard Carbon Capture and Storage (OCCS)

Onboard carbon capture already exists technically, but still counts for nothing toward EEXI or CII: the full regulatory framework is not expected before 2028, a gap holding back large-scale adoption.

### Shore Power and Cold Ironing (Onshore Power Supply)

From 1 January 2030, container ships and passenger ships above 5,000 GT will have to connect to shore power at major EU ports: only 58% of European ports currently have this capability.

### Wind-Assisted Propulsion Systems (WAPS)

Rotor sail, wing sail, suction sail or kite: every ton of fuel saved by an auxiliary wind propulsion system is simultaneously a cost saving, a CII improvement, and an avoided compliance cost.

### Methanol and Ammonia Bunkering: Infrastructure and Real Cases

48 ports offer methanol bunkering versus over 200 for LNG: the real constraint on the transition to alternative fuels today is less the ship than the port infrastructure available to supply it.

### Just Transition and the Social Impact of Decarbonization

Up to 800,000 seafarers could require professional retraining by the mid-2030s under a full-decarbonization scenario: the maritime sector's energy transition is also, and perhaps above all, a question of people.

### Review of the EU MRV Framework in Light of the EU ETS

The EU MRV Regulation existed years before the maritime EU ETS, but since 2023 has been rewritten piece by piece to become the data infrastructure the entire allowance-trading mechanism rests on: understanding its evolution separately from the ETS gives an incomplete picture.

### CII: 2027-2030 Reduction Factors and New SEEMP Granularity

The revised SEEMP Part II with the new Confirmation of Compliance is not a 2027 obligation: it was already required on board from 1 January 2026, with transport work data that many ships were not yet collecting.

Coming in future updates to this module: outcome of the formal adoption of the Net-Zero Framework expected at MEPC 85 (October 2026) after the extraordinary October 2025 session ended without agreement, operational details on managing Remedial Units and ZNZ credits once the framework is definitively adopted, Phase 2 of the CII review on the AER metric across the 2026-2028 MEPC sessions.
