Independent verification is fundamental to the GGL certification scheme.

GGL develops and governs the certification scheme. Certification Bodies independently assess organisations and issue certificates in accordance with the applicable accreditation requirements. This separation of responsibilities safeguards impartiality and strengthens confidence in certification.
