Over a period of 2 years, GRI and its partners will work with media companies and their stakeholders to develop a set of reporting guidelines specifically for media companies. In line with GRI policy, the sector specific guidelines will be developed in a consensus seeking process involving a multi-stakeholder Working Group consisting of members from all parts of the world.

The development of the Sector Supplement will consist of four phases- Project Initiation, two consecutive Implementation Phases and the Project Output.  During project initiation, GRI engages with companies within the sector, finalizes the budget and recruits members for the Working Group.  The first implementation phase will include at least 3 Working Group meetings where Working Group members will identify material sector sustainability issues and draft indicators.  The findings will be submitted for a public survey. 

The second Implementation phase will consist of 2 Working Group meetings during which feedback from the public survey will be reviewed, indicators from implementation phase 1 refined and indicator protocols drafted.  The indicators and indicator protocols will then be subjected to a Public Comment Period of 90 days, after which the final draft version of the Sector Supplement will be presented to the GRI Technical Advisory Committee and Board of Directors for approval.  Once it is approved the Project Output will be a Media Sector Supplement to be used by all media companies.
