16 maritime compliance frameworks — EU ETS, FuelEU Maritime, IMO CII, UK ETS, Sea Cargo Charter, IMO GFS 2028, Biofuel blending, US EPA/CARB, and more. All calculated the moment you log a voyage. No separate tools. No duplicate entry. Ready to submit.
The European Union Emissions Trading System requires vessel operators to surrender carbon allowances for every voyage that starts or ends in an EU port. VEMO FuelIQ calculates your exact EUA liability per voyage leg and tracks your annual exposure in real time so you are never caught short at year end.
FuelEU Maritime sets GHG intensity targets for vessels calling EU ports from 2025. The regulation tightens every five years to 2050. VEMO FuelIQ tracks your GHG intensity score per voyage and projects your full year position so you can act before penalties apply.
The Carbon Intensity Indicator grades every vessel A through E based on its annual carbon intensity. VEMO FuelIQ recalculates your CII grade after every voyage logged and shows you exactly what you need to do to maintain or improve your rating before year end. EEXI attained value is calculated automatically.
IMO Data Collection System requires annual fuel oil consumption reporting to flag states. EU MRV requires verified emissions data for all EU port calls. VEMO FuelIQ auto generates both reports from your existing voyage data and exports them in the exact format required with no additional input needed.
Boil Off Gas guarantee clauses in charterparties define the contractual BOG rate for every voyage. If actual BOG exceeds the guarantee the charterer may claim a penalty worth millions. VEMO FuelIQ tracks actual vs guaranteed BOG per voyage and flags any variance automatically so you have the evidence to defend or dispute every claim.
The Sea Cargo Charter is a voluntary but commercially critical framework. Major charterers — Cargill, Trafigura, Louis Dreyfus, Shell, BP and Vitol — require annual CII alignment reports before placing cargo. A misaligned vessel faces outright chartering exclusion or steep rate discounts. VEMO FuelIQ calculates your SCC alignment score from the same CII data used for IMO submission — no duplicate work.
| Charterer | Framework | Status |
|---|---|---|
| Cargill | Sea Cargo Charter | Signatory |
| Trafigura | Sea Cargo Charter | Signatory |
| Louis Dreyfus | Sea Cargo Charter | Signatory |
| Shell | Sea Cargo Charter | Signatory |
| BP | Sea Cargo Charter | Signatory |
| Vitol | Sea Cargo Charter | Signatory |
VEMO FuelIQ produces the Sea Cargo Charter annual report as a one-click CSV export from existing voyage data — no additional logging required.
The IMO Net Zero Framework was finalized at MEPC 83 in April 2025 and becomes mandatory from 1 January 2028 for all ships over 5,000 GT. It introduces a GHG Fuel Intensity (GFI) standard and a financial levy — non-compliant vessels pay up to $380 per tonne CO₂e deficit into the IMO Net Zero Fund. VEMO FuelIQ calculates your GFI, compliance status, and projected levy from day one.
| Fuel | WtW EF (gCO₂e/MJ) | 2028 Status |
|---|---|---|
| LNG Fossil | 68.5 | ✓ Compliant |
| VLSFO | 91.7 | ✗ Levy applies |
| HFO | 93.3 | ✗ Levy applies |
| Bio-LNG (waste) | 7.6 | ✓ Full surplus |
| e-Methane (RFNBO) | 4.8 | ✓ Full surplus |
| Green H₂ | 3.16 | ✓ Full surplus |
LNG operators have a ~6 year advantage over HFO/VLSFO operators who face levies from day one in 2028. VEMO FuelIQ quantifies this advantage in exact dollar terms per vessel.
Blending bio-LNG, e-methane, HVO or green hydrogen into your bunkering directly reduces your vessel's Well-to-Wake GHGii — the single number that drives FuelEU compliance, IMO GFS levy exposure, and Sea Cargo Charter alignment. VEMO FuelIQ's built-in blend calculator shows exactly what percentage of each fuel pathway you need, when you need it, and what it saves.
| Fuel Pathway | WtW EF | RFNBO Credit |
|---|---|---|
| LNG Fossil | 68.5 gCO₂e/MJ | None |
| Bio-LNG (waste, Annex IX-A) | 7.6 gCO₂e/MJ | None |
| Bio-LNG (crops, Annex IX-B) | 23.8 gCO₂e/MJ | None |
| e-Methane / RFNBO | 4.8 gCO₂e/MJ | 2× until 2033 |
| HVO (waste oils) | 15.4 gCO₂e/MJ | None |
| Green H₂ | 3.16 gCO₂e/MJ | 2× until 2033 |
| Green NH₃ | 5.8 gCO₂e/MJ | 2× until 2033 |
The North American Emission Control Area (ECA) applies strict NOx Tier III limits within 200 nautical miles of the US coast. California's CARB OGV regulation adds a 24-nautical mile sulphur limit and mandatory shore power requirements at major California ports. VEMO FuelIQ checks ECA compliance per voyage and flags CARB obligations for US port calls automatically.
| Fuel | NOx Tier III (ECA) | CARB SOx (24nm) |
|---|---|---|
| LNG (Otto-cycle) | ✓ Auto-compliant | ✓ 0.0% sulphur |
| LNG (MEGI high-pressure) | SCR may be needed | ✓ 0.0% sulphur |
| LSMGO / MDO | Engine-dependent | ✓ 0.1% sulphur |
| VLSFO | Engine-dependent | ✗ 0.5% — switch fuel |
| HFO | ✗ Non-compliant | ✗ 2.5% — prohibited |
LNG is the only fuel that is automatically compliant with every US ECA requirement — NOx, SOx, and CARB — with no switching, scrubber, or SCR required.
