Decoding Maritime Emissions Q2 2026: Efficiency Hidden in Details

In Q2 2026, VesselBot tracked 86,389 voyages across 6,523 container-carrying vessels, recording a fleet average Well-to-Wake emissions intensity of 231.7 g CO₂e per TEU km.

But that fleet-wide figure tells only part of the story. Average emissions intensity varied by as much as 161% between vessel sizes, while carrier performance changed depending on the route and even averages for the same carrier concealed substantial differences between individual voyages.

This webinar takes a closer look at VesselBot's Q2 2026 containership data to show why emissions efficiency is hidden in the operational details, and why understanding how vessels and carriers actually execute individual voyages matters for emissions measurement, benchmarking, and carrier selection.

What you will learn:

• How vessel size affects emissions efficiency, with average WtW emissions intensity ranging from 284.5 g CO₂e per TEU km for Feeder vessels to 108.8 for VLCS.
• How voyage characteristics change across major fronthaul routes, including significant differences in transit time, port time, distance and utilization.
• Why the most efficient carrier changes depending on the route, and what that means for evaluating carrier performance.
• What drove a 37.4% difference in average emissions intensity between Yang Ming and Maersk on the China/East Asia–West Coast North America trade.
• Why carrier averages can still hide significant voyage-level variation, and what individual voyage execution reveals about emissions performance. 

Who should watch

Logistics managers, procurement leaders, and sustainability professionals who rely on container shipping and need a more granular understanding of vessel, route, carrier, and voyage performance to improve emissions measurement and make more informed carrier selection decisions.
