TAC Terms of Reference

The function of the TAC is to manage technical matters relating to the development of the MarinTrust certification criteria, including the technical validity of MarinTrust as a third-party accredited certification programme.

Main Objective

Support the development and implementation of a credible and robust certification programme for the marine ingredient industry, to provide assurance to the global supply chain that all certified factories are run in a responsible and ethical way.

Key Activities

  • Develop the technical specifications of the certification programme to ensure relevance to current practice and market requirements, for approval by the MarinTrust Governing Body Committee.
  • Provide guidance for assessment purposes, on the accurate interpretation of the MarinTrust Standard, using industry member and environmental knowledge.
  • Provide advice to the Governing Body Committee through decisions, proceedings and meeting minutes, about suggested amendments to ensure the accuracy, relevance and credibility of the programme.
  • Provide input on documents for the technical interpretation of the MarinTrust certification criteria, and on technical guidance documentation used in the assessment of marine ingredient manufacturers.
  • Monitor changes to the FAO or ILO normative documents, or new guidance relevant to fisheries assessment, including any legislative documentation used in the MarinTrust programme, and incorporate such changes into the certification criteria.

  • Antoine Dangy – OLVEA Fish Oils
  • Duncan Leadbitter – Fish Matter (E-NGO)
  • Estelle Brennan – Lyons Seafood (Fish Procesor)
  • Francisco Aldon – MarinTrust (Marine ingredients/Standard holder)
