Confidentiality is crucial for the GNR system. Companies must be confident that their sensitive information is secure. The GNR must be compliant with all anti-trust legislation.

To ensure the confidentiality of the GNR system and of individual datasets submitted by participants, PricewaterhouseCoopers (PwC) was selected to manage the system as a Third party, external and independent from participants. PwC develops the database system, collates the reported data, analyzes the results of various statistical queries, and produces consolidated data and reports.

As the independent manager of the GNR system, PwC is responsible for ensuring that all data that can be traced back to individual companies or plants will strictly not be disclosed, not be accessible to any unauthorized internal and external stakeholder. PwC also provides a guarantee of non-disclosure of confidential information and compliance with competition law. Within PwC, IT audits are regularly organised to ensure the adequate performance of the IT structure in place.

In addition, a Project Management Committee (PMC) was set up to serve as the single contact point for all communications between participants in the GNR system and PwC. The PMC develops the schedule for companies' data submittal to PwC, and receives and deliberates on stakeholder requests for data.
