PureMetrics

Core Features

PureMetrics calculates emissions through continuous, direct measurement at the exhaust stack. This instrumentation-led approach captures methane slip and CO₂ in real operating conditions and is designed to remove the need for estimated fuel-consumption factors in EU MRV and IMO DCS reporting. Below are some core capabilities documented for PureMetrics:

• Direct stack measurement (real-world data): PureMetrics uses "stack measurement" to track and report GHGs from maritime and land-based engines—crucial for methane slip quantification.

• Regulatory-ready outputs: Updates aim to eliminate fuel-estimate workarounds for EU Monitoring, Reporting & Verification (MRV) and IMO Data Collection System (DCS), simplifying compliance submissions.

• Gold Standard-approved reporting: Daphne states that PureMetrics reporting meets Gold Standard criteria, supporting trusted, verifiable emissions accounting and potential access to credits.

• Audit and comparison tools: The “PureMetrics-Compare” function lets users reconcile noon-report fuel data with direct measurements, strengthening audit trails and method benchmarking.

• Integration with methane-abatement systems: When paired with SlipPure™, PureMetrics quantifies abatement in real time and produces auditable reports of reduction performance.

• Multi-asset coverage. In addition to ships, PureMetrics is described as applicable to land-based combustion engines; Daphne also provides a portal to explore MRV-reported maritime assets.

Closing Insights

PureMetrics is already being used in distinct ways by major brands. Trafigura announced a commercial deployment on an LNG carrier to obtain precise MRV data and optimize GHG emissions, an example of using continuous measurement to tighten compliance and operational control. AET has also recently piloted PureMetrics on two LNG dual-fuel vessels (Eagle Ventura and Eagle Bintulu) to improve emissions transparency and investigate methane-reduction strategies, demonstrating value for tanker operators transitioning fuel types.

The outlook is strengthened by third-party assurance and market reach. Lloyd’s Register granted Approval in Principle to the system’s stack-measurement approach, while Daphne’s Singapore subsidiary expands support for Asia-Pacific fleets and broader maritime adoption. For buyers, the combination of Gold Standard-approved reporting, reconciliation tools such as PureMetrics-Compare, and possible pairing with abatement technology creates a measurement-plus-mitigation pathway that satisfies auditors and unlocks decision-grade insights. Daphne’s customer portal and public asset views further indicate a maturing product ecosystem oriented to continuous improvement and credible reporting.
