A framework by the maritime industry, for the maritime industry — collaboratively developed and globally harmonised
Coordinated by the Tripartite Joint Industry Working Group (JIWG)
Call for Industry Consultation
The Tripartite JIWG invites shipowners, operators, charterers, classification societies, technology providers, verifiers, port authorities and regulators to engage in this work.
The initiative aims to establish and adopt a common business process and associated data exchange protocol for emission-related data, enabling reporting that is accurate, efficient and verifiable.
It seeks to:
- Ensure consistency and interoperability in emissions data reporting across the global maritime sector
- Facilitate seamless data exchange between ship operators/owners, verifiers, flag states and relevant authorities
- Ensure the reporting framework is based on open, non-proprietary standards
- Support the uptake of a harmonised data set based on the IMO Compendium, ensuring alignment with existing international standards.
Why this work matters
Mandatory emissions reporting requirements for ships have expanded significantly in recent years, including under IMO DCS and EU MRV. As a result, shipowners, software providers and verifiers face increasing complexity in collecting, mapping, validating and exchanging emissions-related data.
Today, no single standardised dataset fully covers the common data points needed across major reporting and verification schemes. This leads to duplication, inefficiency and avoidable risk of error, particularly where data must be transformed manually between different systems and formats.
A common framework can help reduce fragmentation, improve data quality and support a more scalable digital infrastructure for maritime emissions reporting.
Towards a common framework for GHG reporting
Tripartite is an industry forum bringing together representatives from shipowners and operators, shipbuilders, and classification societies to address shared technical, safety, environmental and regulatory challenges through coordinated, non binding industry dialogue.
The JIWG was established at the 2024 Tripartite meeting to address the growing need for a common, reliable and industry-wide approach to the digital reporting of emissions-related data.
The work is divided in three parts:
- Development of a comprehensive standardised dataset and associated formats for emissions reporting, directly linked to the IMO Compendium
- Development of a business process description and related protocols for transmitting data across relevant emissions reporting schemes, based on the Operational Vessel Data (OVD) standard
- Development of standardised Vessel Emissions Reporting (VER) formats for commercial use cases, including outputs, verification status and user-defined reporting periods.
Invitation for industry consultation
In reviewing existing solutions, the JIWG identified DNV’s Operational Vessel Data (OVD) standard, which is supported by more than 60 stakeholders, with possible connectivity to majority of the world fleet through its implementation on the Veracity platform, as a mature and operationally tested candidate that could serve as a practical baseline for further development.
The purpose of this consultation is to gather industry feedback on whether this approach reflects operational reality and is usable across different ship types, trading patterns and business models. Feedback is particularly welcome where it helps clarify definitions, improve usability or identify implementation gaps.
The JIWG therefore invites the maritime industry to review and comment on the proposed use of OVD as a baseline for a common framework for exchanging log abstract and noon report data for GHG reporting.

Consultation details
Consultation opening date 1 July 2026
Consultation closing date 31 August 2026
The JIWG will also organise an open workshop during SMM Hamburg on 2 September 2026 to explain the concept and invite further input from a broader audience.
Following the close consultation, the JIWG will organise an open webinar on 15 October 2026. Please save the date; further details will be shared in due course.
