Rhesis Green Label Standards
The Rhesis Green Label is a technical standard for digital sustainability. It defines measurable efficiency thresholds designed to reduce global energy impact through Digital Quality, and recognises the websites that meet them.
The standard measures. It does not rank, review or sell placement.
Validation is performed by analyzing the website's Home Page. Data is audited using objective parameters from Google PageSpeed Insights, across all four areas (Performance, Accessibility, Best Practices, SEO), on both Mobile and Desktop configurations. The score must be reached in every single area, never as an average.
- 60/100 — a website. It answers for itself.
- 70/100 — a directory listing other websites. It answers for what it hosts.
- 80/100 — an agency or consultant building sites for others. It answers for what it produces.
The measurement is public and repeatable: anyone can run the same test and obtain the same result.
- Official Badge: the right to display the Rhesis Green Label logo, carrying the validation period.
- Rhesis FM Integration: priority in the Digital Quality filter of the Rhesis FM search engine.
- Public Register: the entry is recorded, so that any badge can be checked.
- Partner Discounts: guaranteed minimum 20% discount on listing fees in any Rhesis Green Directory.
Recognition lasts two years. Periodic audits apply: notification if any area falls below the threshold, 30 days to restore it, revocation if it is not restored.
- €25 for two years, payable only after technical eligibility is confirmed. Renewal €25.
- €12.50 (50% discount) for sites already listed in a partner Rhesis Green Directory.
We charge for measurement, never for the right to reference the standard. The Observatory may also validate and list websites by its own initiative. Removal can be requested at any time.
Adopting directories apply this policy as a good-faith admission filter, based on each site's self-declaration: a lighter duty of verification, not a lower standard. Responsibility for compliance rests with each listed website.
