CII / EEXI dashboard — IMO carbon intensity

The Sustainability tab shows the live CII (Carbon Intensity Indicator) trajectory for every vessel and the rolled-up fleet view — the regulatory metric IMO uses to grade vessel emissions performance.

What CII measures:
Annual CO2 emissions divided by transport work (deadweight × distance). Each year IMO sets reference values; vessels are graded A (best) through E (worst). E-rated vessels three years running face mandatory corrective action plans.

The dashboard:
• Per-vessel current CII vs. annual target line
• Year-to-date trajectory — projecting where the rating will land at year-end if the trend holds
• What's-driving-it breakdown — bunker consumption, distance sailed, deadweight utilisation

Inputs:
• Bunker log (Fleet → Bunkers) — fuel grades and quantities
• Voyage records (Bridge → Routing or Voyages) — distance and deadweight
• No manual data entry — the rating is always current

Levers Wally surfaces:
• Slow steaming on long passages — typically the biggest available improvement
• Hull cleaning frequency — fouling compounds CII faster than most operators realise
• Trim optimisation — the right ballast distribution can save 2–5% on fuel for the same speed

The same data backs the regulatory annual reports. Generate the EU-MRV emissions report or IMO-DCS submission directly from the Sustainability tab.
