Shipping

For container, bulk, tanker and Ro-Ro fleets, decarbonization blends operational efficiency (voyage planning, slow steaming, weather routing, hull/propeller maintenance) with fuel transition (LNG, biofuels, methanol, ammonia), shore power at berth and emerging wind-assist technologies. Key challenges include CII/EEXI compliance, EU ETS & FuelEU alignment, bunkering data quality, and asset retrofit cycles.

Key drivers & challenges

  • Voyage optimization: weather routing, just-in-time arrivals, slow steaming.
  • Fuel shift: VLSFO → LNG / biofuels / methanol / ammonia; dual-fuel retrofits.
  • Hull/propeller efficiency: coatings, polishing, air lubrication, rotors & wing sails.
  • Shore power / cold ironing at ports; terminal electrification.
  • Compliance: IMO DCS, CII/EEXI, EU MRV, EU ETS, FuelEU Maritime.
Scope 1 — Onboard
  • Main & aux engines, boilers: VLSFO/MGO/LNG/biofuels/methanol.
  • Refrigerants (reefer units/HVAC), fugitive fuel losses.
  • Onboard generators during cargo ops at anchor/berth.
Scope 2 — Electricity
  • Shore power consumption at berth (cold ironing).
  • Terminal/office electricity for owned facilities.
  • Location vs market-based factors by port/region.
Scope 3 — Upstream
  • Fuel well-to-tank, lubricants, spare parts, provisions.
  • Vessel construction (hull, engines), dry-docking capital goods.
  • Bunkering logistics and supplier activities.
Scope 3 — Downstream
  • Port services, third-party terminals, landside drayage.
  • Sold transport services disclosures (gCO₂/TEU-km or t-km).
  • End-of-life vessel recycling and scrap credits.

Compliance & Frameworks

IMO DCS / CII / EEXI

Automated voyage logs, fuel & distance, attained vs required CII, EEXI documentation.

EU MRV / EU ETS

CO₂ per voyage/port call; allowance tracking & surrender planning for EU legs.

FuelEU Maritime / CSRD

GHG intensity of energy used, shore power use, and entity-level ESRS reporting.
