Decoding Maritime Emissions, Q1 2026:
Efficiency Under Pressure
Report
Voyage-level emissions analysis across 82,212 container voyages
Built from operational data across 6,187 container-carrying vessels, this report reveals how utilization, vessel size, carrier practices, port selection, and geopolitical disruptions are reshaping emissions performance across the global container fleet.
In Q1 2026, average Well-to-Wake emissions intensity across container shipping reached 208.2 g CO₂e per TEU-km. But fleet averages conceal major operational differences.
Within the same quarter:
- Very Large Container Ships recorded emissions intensity as low as 55.2 g CO₂e per TEU-km
- Feeder vessels exceeded 266 g CO₂e per TEU-km
- Even among the most efficient carriers on the same trade lane, Well-to-Wake emissions might differ up to 24%
The report shows why those differences occur and why fleet-level benchmarks fail to reflect the emissions reality of individual shipments.
Inside the report, you’ll discover:
- Why aggregated emissions benchmarks cannot reflect the operational reality of an individual shipment
- Ηow utilization and vessel size constitute primary factors in determining a voyage's efficiency
- Why do carriers on the same trade lane produce materially different outcomes, and what drives this difference
- How port-pair selection can influence emissions intensity as much as route design
- What voyage-level execution data reveals about carrier selection, network design, and compliance planning
