Daphne Technology’s PureMetrics™ has received DNV validation for direct CO2 emissions monitoring, offering a certified alternative to fuel-based calculations under EU MRV Method D. This milestone provides shipowners with the high-integrity data needed to manage financial exposure under EU ETS and FuelEU Maritime regulations.
Switzerland | May 12, 2026 – In a move that brings much-needed precision to the carbon markets, Daphne Technology has announced that its PureMetrics™ system has received a Statement of Compliance from DNV. This validation confirms the system’s suitability for direct CO2 measurement under the EU MRV (Method D) and MEPC.395(82) frameworks.
As the maritime industry shifts from estimated data to verified reality, this certification provides a “technically reviewed reference point” for shipowners looking to optimize their financial exposure under the EU ETS and FuelEU Maritime.
Breaking the “Method D” Barrier
Historically, “Method D” (direct measurement) has seen limited adoption due to the sheer difficulty of maintaining sensor accuracy in harsh, variable exhaust conditions. Daphne Technology has solved these legacy challenges through a sophisticated three-pillar approach:
- Adaptive Sensor Compensation: Maintaining accuracy despite fluctuating exhaust flows.
- Audit-Ready Automation: Automated calibration logs that eliminate manual data tampering.
- Cloud Integrity: A secured data pipeline with direct access for verifiers, ensuring a “single source of truth.”
Proven Under Real-World Conditions
DNV’s validation wasn’t just theoretical. The assessment was based on rigorous onboard testing aboard a commercially operating dual-fuel vessel. The process included:
- Operational Testing: Measuring real-time emissions in transit.
- Comparison Analytics: Validating direct measurements against traditional fuel-consumption-derived data.
- Flow Determination: Reviewing how the system calculates exhaust gas flow to ensure absolute CO2 mass accuracy.
From Technical Readiness to Regulatory Trust
Ivan Raleff, Managing Director of Daphne Technology SA, commented, “Direct measurement has seen limited adoption partly because the path from technical readiness to regulatory acceptance has been unclear. The DNV Statement of Compliance provides operators and verifiers with a technically reviewed reference point for implementing Method D reporting.”
The Financial Dimension: Calculation vs. Measurement
Under current industry standards, most vessels calculate CO2 based on Bunker Delivery Notes (BDNs) and standard emission factors. However, for dual-fuel vessels, combustion efficiency and fuel composition vary.
In the era of the EU ETS, where shipowners must surrender allowances for every tonne of carbon emitted, the gap between “estimated” and “measured” emissions is no longer just a technicality, it is a direct financial cost. PureMetrics™ allows operators to pay for what they actually emit, not what a formula estimates they emit.
Future-Proofing: Beyond CO2
While the current DNV validation focuses on CO2, the PureMetrics™ platform is designed for the total GHG picture. With Methane (CH4) and Nitrous Oxide (N2O) included in EU MRV reporting from 2024, Daphne Technology is already progressing toward dedicated methane measurement validation.
Furthermore, Daphne and DNV are integrating through the DNV Veracity platform via API, creating a seamless, end-to-end digital workflow that takes data from the exhaust stack directly to the regulator’s desk.
