EU ETS 2026: The Methane Question That's Changing Shipping Costs
The EU Emission Trading System (ETS) has reached a critical milestone. From January 2026, shipping companies must surrender allowances covering 100% of their CO₂e emissions on EU-related voyages—up from 70% in 2025. But the bigger story this year is the expansion of covered greenhouse gases to include methane (CH₄) and nitrous oxide (N₂O).
Why Methane Matters Now
Methane has a global warming potential approximately 28 times higher than CO₂ over a 100-year period. Nitrous oxide? Approximately 265 times more potent.
For carriers that have bet big on LNG as a transitional fuel, this creates a uncomfortable reality: while LNG-powered vessels emit less CO₂ than conventional heavy fuel oil, they face methane slip—uncombusted methane passing through the engine into the exhaust. Even a small slip rate can significantly erode LNG's climate benefit and, from 2026 onwards, directly increase compliance costs.
Carrier Strategies Diverging
The major carriers have taken markedly different approaches:
| Carrier | Primary Fuel | Forward Bet | Net-Zero Target |
|---|---|---|---|
| Maersk | Biofuels + grey methanol | Green methanol | 2040 |
| Hapag-Lloyd | LNG | Methanol (2028+) | 2045 |
| CMA CGM | LNG / biomethane | Methanol + ammonia | 2050 |
| ZIM | LNG (ammonia-ready) | Ammonia | 2050 |
| MSC | LNG | Multi-fuel | 2050 |
What Shippers Need to Know
The inclusion of methane and N₂O is a direct signal that fuel strategy is no longer just a carrier's ESG concern—it directly affects the surcharges you pay.
Carriers running large LNG fleets will face higher EU ETS surcharge exposure unless they can demonstrate low methane slip rates or offset with bio-LNG. Those operating on biofuels or green methanol face lower GHG intensity and potentially lower surcharges.
The opportunity: Shippers can now actively select carriers whose fuel strategy aligns with their own Scope 3 emissions targets.
The Infrastructure Gap
Here's the uncomfortable truth: all these strategic choices raise one fundamental question—will ports actually be able to deliver the fuel?
- LNG: Over 200 ports with bunkering facilities, but demand is outpacing supply
- Green Methanol: Only ~48 ports globally—well below what's needed
Key Takeaways
- 100% ETS coverage is now in effect for EU maritime voyages
- Methane slip is the new cost variable for LNG-powered vessels
- Carrier selection now has direct financial implications via ETS surcharges
- Fuel infrastructure remains the bottleneck for the energy transition
The message is clear: understanding fuel strategy isn't optional anymore—it's a compliance and cost imperative.
