Rhesis Green Label: International Standard
Digital Sustainability
The Rhesis Green Label project defines sustainability and performance parameters for a conscious web. Our goal is to promote websites that meet technical efficiency thresholds designed to reduce global energy impact through Digital Quality.
The project was conceived by SEO consultant Giacomo Gallo, developed in collaboration with Ieros web agency and under the scientific direction of IrisForm, an independent non-profit research institute focused on digital ethics and quality. It addresses a concrete problem: the web's growing energy footprint. Every poorly optimized page consumes more server resources, more bandwidth, and more energy. The Green Label sets a measurable, verifiable standard to counter this trend.
While web-agency.one continues to showcase digital excellence across international markets, the official technical hub and the validation processes are managed by the Rhesis FM infrastructure — a global-oriented search engine built around the principles of Digital Quality and environmental sustainability.
This observatory adopts the standard as a Rhesis Green Directory: the sites it lists are validated on the same public parameters.
Validation Criteria
Validation is performed by analyzing the website's home page across all four areas (Performance, Accessibility, Best Practices, SEO), on both Mobile and Desktop configurations. The threshold must be reached in every single area, never as an average, and depends on the type of site:
- 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.
This ensures a structurally optimized website that measurably reduces energy consumption and CO2 emissions from data loading.
Validated sites are included in the official Rhesis Observatory, receive priority indexing in the Rhesis FM search engine under the Digital Quality section, and earn the right to display the official Rhesis Green Label badge. Recognition lasts two years.

Monitoring and Compliance
Inclusion in the Rhesis FM search engine under the Digital Quality section is subject to periodic audits. Sites that fall below their applicable threshold are notified to restore technical parameters within 30 days to avoid revocation. The Observatory may also validate and list websites by its own initiative; removal can be requested at any time.
