Topic Standard Project for Water and Effluents
Best practice for measuring and reporting on water impacts
Access to freshwater is essential for human life and wellbeing and is an internationally recognized human right. Through a deep understanding of their water use, organizations can assess the impacts they have on water resources that benefit the ecosystem, other water users, and the organization itself. This, in turn, informs effective water management.
GRI 303: Water and Effluents 2018 will be effective for reports and other materials published on or after 1 January 2021. Earlier adoption is encouraged.
About the project
In 2016, the Global Sustainability Standards Board (GSSB), GRI's independent standard setting body, initiated a project to review and update GRI 303: Water 2016. The aim of this project was to ensure that the Standard aligns with internationally agreed best practice and reflects recent developments in water management and reporting.
A multi-stakeholder working group appointed by the GSSB began its work on the project in December 2017. Two public comment periods were held for the project. All received comments were considered by the Water Working Group and the GSSB.
In April 2018, the GSSB approved the updated Standard GRI 303: Water and Effluents 2018. The project followed the GSSB Due Process Protocol, the implementation of which was overseen by the Due Process Oversight Committee.
Basis for conclusions
A first exposure draft of the updated Water and Effluents Standard was made available for a 60-day public comment period between 10 August to 9 October 2017.
Following revisions based on the received comments, a second exposure draft was made available for a 60-day public comment period between 20 December 2017 to 18 February 2018.
The GSSB Basis for conclusions provides a summary of the public comments received. It also provides a summary of how the GSSB responded to these comments in finalizing the Standard.
