Co-Auditor Feedback

Invite, validate, and strengthen your event's sustainability results.

What is a Co-Auditor?

A Co-Auditor is a trusted participant (staff, volunteer, partner, or attendee) who provides independent, on-site feedback to help validate sustainability practices during the event.

How the Co-Auditor Process Works

1. Generate a QR Code

Create a unique QR code linked to your Co-Auditor Survey.

Share this QR code on-site with selected participants.

2. Co-Auditor Completes the Survey

The Co-Auditor answers a short survey based on what they personally observed at the event, such as:

  • Waste segregation and signage
  • Use of digital vs printed materials
  • Reduction of single-use plastics
  • Sustainability messaging visibility

Optional photos may be uploaded to support responses.

3. Validation of Results

Co-Auditor responses help:

  • Confirm reported sustainability practices
  • Adjust scores where evidence is limited
  • Strengthen the credibility of final results

This ensures the assessment reflects actual on-site practices, not just self-reported data.

4. Contribution & Certification

Co-Auditor feedback is integrated into the Sustainability Performance score.

Co-Auditors receive a Co-Auditor Certificate in recognition of their contribution.

Who Are the Co-Auditors?

Co-Auditors are event attendees who help validate sustainability practices by sharing what they personally observed during the event.

How the QR Code Works

  1. Generate the QR Code. Click "Show QR Code" to generate a unique QR code linked to the Co-Auditor Survey.
  2. Invite Attendees to Participate. Display the QR code on-site and invite attendees to scan it and act as co-auditors.
  3. Scan & Submit Feedback. Attendees scan the QR code using their mobile device and answer a short survey based on what they observed (e.g., waste segregation, use of digital materials, reduction of single-use plastics).
  4. Validation & Integration. Attendee feedback helps confirm reported practices and strengthens the credibility of the final sustainability results.

Best Practices

  • Display the QR code in visible areas during the event
  • Encourage honest, observation-based responses
  • Photo uploads are optional but help with validation
