About

The SCI Self-Certification Program enables organizations to self-certify their Software Carbon Intensity calculations under the ISO/IEC 17050 supplier's declaration framework.

GSF verifies disclosure completeness, not calculation accuracy. All approved submissions are published on GitHub for community review and validation. This is not third-party certification or accredited conformity assessment.
