- EU MRV data must be verified in THETIS by 31 March 2026.
Shipping companies need to navigate a two-step submission process to get timely verification from Lloyd’s Register. The first stage is all about sharing fleet and voyage details for every vessel that docked at EU and UK ports in 2025. In the second stage, companies will upload specific ship-level data and necessary documents through the Emissions Verifier portal. It’s crucial to meet both deadlines so that LR can kick off the verification process and ensure compliance with FuelEU, MRV, and ETS regulations, reports LR.
Stage 1 Submission to LR by December 15, 2025
Send your information to LR via email:
- Total number of vessels that called at EU & UK ports in 2025
- Number of voyages for each vessel
Stage 2 Data Upload by January 15, 2026
Upload your ship data and supporting documents through the Emissions Verifier portal. Check out the MRV Evidence Pack and FuelEU Evidence Pack for more details.
