Project update 

A 75-day public comment period for the exposure draft of the GRI Standard on waste ran from 1 May to 15 July 2019.

The Global Sustainability Standards Board (GSSB), GRI's independent standard-setting body, received submissions from 59 respondents on behalf of organizations or individuals. The submissions received are published here.

All public comments received will be considered by the multi-stakeholder Project Working Group, as well as the GSSB, which will inform the further development of the standard, following the project timeline below. 

About the project

The GSSB is overseeing a project to review and update the content of waste disclosures in GRI 306: Effluents and Waste 2016 in 2018 and 2019.

The project's objective is to review and update the waste-related content of GRI 306: Effluents and Waste to ensure it is in line with internationally-agreed best practice and reflects recent developments in waste management and reporting. The scope of work includes updating, expanding or deleting existing content, where appropriate.

The scope of this review also includes the materials-related disclosures from GRI 301: Materials 2016.

The project follows the GSSB Due Process Protocol, the implementation of which is overseen by the Due Process Oversight CommitteeIn line with this protocol, a multi-stakeholder Project Working Group has been formed to develop content for the review of waste disclosures in GRI 306.
