Lloyd’s Register has issued a Factual Statement at Gastech 2026 confirming that Daphne Technology’s PureMetrics™ continuous emissions monitoring system is suitable for directly tracking greenhouse gases and pollutants from marine diesel and dual-fuel engines. Based on a comprehensive Design Appraisal and onboard testing, the generic system validation aligns with key regulatory standards including IMO Resolution MEPC.416(84) and EU MRV requirements. This independent verification provides shipowners with a reliable technical foundation for accurate emissions reporting and compliance, particularly for carbon dioxide and methane under the EU Emissions Trading System.
Bangkok, Thailand | September 17, 2026 – Lloyd’s Register (LR) has formally issued a Factual Statement confirming that Daphne Technology’s PureMetrics™ continuous emissions monitoring system (CEMS) is suitable for directly monitoring selected greenhouse gas (GHG) and pollutant emissions from marine diesel engines onboard ships.
The official presentation of the Factual Statement took place during the ongoing Gastech 2026 conference in Bangkok, highlighting a major step forward in independent validation for marine emissions reporting technologies.
Comprehensive Design Appraisal and Scope
The independent assessment involved rigorous documentation review and onboard demonstration testing, culminating in an LR Design Appraisal of the PureMetrics™ system architecture and its underlying emissions calculation methodology.
Unlike a vessel-specific approval, the appraisal covers the system’s generic design, establishing a robust technical foundation that shipowners and operators can leverage for future ship-specific classification and regulatory certification processes.
According to the appraisal, PureMetrics™ is engineered to monitor a broad spectrum of emissions, including:
- Greenhouse Gases: Carbon dioxide (CO2) and methane (CH4).
- Regulated Pollutants: Carbon monoxide (CO), nitrogen oxides (NO and NO2), and sulphur dioxide (SO2).
The system is optimized for deployment across traditional marine diesel engines as well as modern dual-fuel engines.
Regulatory Alignment: IMO, EU MRV, and MEPC.416(84)
LR evaluated the monitoring technology against key international and regional regulatory frameworks, including the International Maritime Organization (IMO) standards, EU MRV (Monitoring, Reporting, and Verification) rules, and the NOx Technical Code.
Significantly, the Factual Statement references IMO Resolution MEPC.416(84), the first dedicated IMO guidelines governing continuous emissions monitoring systems for marine diesel engines, which was recently adopted at the IMO’s 84th MEPC session in 2026.
This validation comes at a critical time for shipowners as compliance tracking intensifies. Alongside CO2, the capability to accurately quantify methane (CH4) is vital, as methane emissions fall squarely under EU MRV reporting requirements and are fully integrated into the EU Emissions Trading System (ETS) starting in 2026.
Industry Leadership Perspectives
“Accurate emissions measurement is becoming increasingly important for shipowners and operators. Our assessment confirms that PureMetrics™ has a sound technical basis for directly monitoring and quantifying emissions from marine engines. The Design appraisal and Factual Statement provide independent validation of the system’s design and methodology, giving the industry greater confidence in the quality and consistency of the emissions data it handles.” said, Max Wu, Lead Specialist, Engine and Emissions Certification Services at LR
“Receiving the Lloyd’s Register Factual Statement and presenting it to shipowners and operators at Gastech 2026 marks another step in the independent validation of PureMetrics™ as a credible basis for direct emissions reporting. The appraisal confirms that the system’s design and methodology meet applicable requirements across a wider scope of greenhouse gases.” said, Ivan Raleff, Managing Director of Daphne Technology SA, Switzerland
