A Northern European ferry operator running routes across the Baltic and North Sea faced a hard deadline: the 2024 expansion of the EU Emissions Trading System to maritime. Under MRV (Monitoring, Reporting, Verification) obligations, the operator was required to track fuel consumption and CO2 emissions at the voyage level across its entire fleet and submit verified reports to flag state authorities.
The problem was structural. Fuel bunkering records sat in one system. Voyage logs came from a separate platform. CO2 calculations were being done by hand in spreadsheets, with no audit trail and no real-time view of the company's growing ETS cost exposure. The compliance team was stretched thin. The risk of error, and the material financial penalty that would follow, was significant.
BASAWE built an end-to-end MRV compliance and EU ETS management platform. AIS voyage data and fuel bunkering records were ingested via direct API integrations, eliminating manual data entry entirely. A CO2 calculation engine applied the EU methodology by fuel type, voyage segment, and distance, covering all 14 vessels and all 38 active routes.
The platform generated MRV reports automatically in the format required by flag state verifiers, replacing what had been a weeks-long manual assembly process. Data lineage was preserved end-to-end, giving auditors a complete traceable record from raw fuel record to final submission.
On the finance side, an ETS cost exposure dashboard tracked the company's real-time allowance position: purchased allowances versus projected obligations based on current voyage activity. This gave the CFO and treasury team the visibility to make informed decisions about allowance procurement well ahead of compliance deadlines.
