Three tanker fleets, one partner
Sea-going tankers under and over 5,000 GT and inland tankers each face a different rule set. Here is where each stands – and what we do for it.
Tankers under 5,000 GT
Proposed in July 2026 (COM(2026) 620): EU MRV from 2029 and EU ETS from 2031 for oil, chemical, gas and LNG tankers of 400–5,000 GT. Still a proposal; agreement expected around early 2027. Start with GM Essential now, grow to GM Advanced – and your first reporting season is calm.
Tankers over 5,000 GT
In scope today: 100% of in-scope emissions under EU ETS since 2026, methane and nitrous oxide included. For LNG and dual-fuel ships, methane slip measured rather than assumed can bring you below the default values. GM Advanced or GM Premium.
Inland tankers
No maritime compliance, but shippers increasingly ask for CO₂ figures. GM Premium Insight: flowmeters on every engine, real fuel and CO₂ per voyage – without the compliance module.
One partner for sea and river
At sea: GM Advanced – a flowmeter on the main engine, full EU MRV, ETS and FuelEU compliance.
On the river: GM Premium Insight – flowmeters on every engine, fuel and CO₂ per voyage, no compliance module.
Timeline: 2026 – 100% ETS for ships over 5,000 GT, CH₄ and N₂O included (in force) · 2029 – EU MRV for tankers of 400–5,000 GT (proposal) · 2031 – EU ETS for tankers of 400–5,000 GT (proposal).
A gas tanker operator runs GM Advanced at sea and GM Premium Insight on the Rhine – with one contact person for both fleets.
