The GSES System is an ESG rating system for companies public organizations, and NGOs. The GSES System works with internationally accepted frameworks and standards such as; GSE Standard, SASB Standards, Blue-Scan, Sustainable Footprint standard, and over 550 ecolabels and certification schemes.

The Meta Standard is an international umbrella standard based on existing certificates and labels. Companies, brands, accommodations, and products can be rated based on the certificates and ecolabels that they already have achieved.

The Meta Standard is measured on 2 levels: 1st and 2nd line, 1st line are certificates that have been checked and issued by an independent certification body that is supervised by an Accreditation Council in the country where it is located. 2nd line are certificates that can be submitted by the organization itself that have not been independently audited by a certification body/institution, these are then checked by an independent audit.
