A broad international consortium has been established to develop the first handbook for Environmental, Social and Governance (ESG) disclosure in relation to marine minerals. The purpose of the guidance document is to enable evidence-based assessments of the ESG performance of marine mineral projects in the context of global standards.

The ESG handbook will be a guidance document to addresses material topics related to marine mineral projects in the deep-sea environment using a standardized approach.

The need for creating a tailored ESG handbook for marine mineral mining, is to specifically address the unique material topics of this new industry and provide guidance for companies to disclose ESG performance of their operations in a consistent manner. The handbook will build upon existing broad ESG reporting standards such as GRI and CDP, and industry specific standards such as IRMA (The Initiative for Responsible Mining Assurance) and Towards Sustainable Mining. The handbook seeks to become a useful disclosure guidance tool for companies, and to enable internal and external stakeholders to access this data in a format that is consistent across the ESG disclosure world. The handbook will not drive any legal framework and is not intended to be used as a compliance tool.

The development of this handbook is also intended to promote ESG thinking and improvements before any commercial activity begins.

The handbook will be based on a collective input from all the collaborating institutions. Furthermore, the project will invite other stakeholders to open hearings and meetings to enable a wider input to the work. The project is open to enter for other collaborating institutions and sponsors.
