CertifiK.io earns an A rating for environmental performance

In a world where digital services are a growing source of CO₂ emissions, French startup CertifiK.io continues to lead by example. The platform has just received an A rating on WebsiteCarbon.com, placing it among the cleanest and most energy-efficient websites on the internet.

A clean, lightweight, and eco-friendly website

WebsiteCarbon assesses websites based on criteria like page size, code efficiency, hosting provider, and CO₂ emissions per visit. The result? CertifiK.io generates an average of 0.21 g of CO₂ per visit, making it cleaner than 91% of tested websites.

This score reflects a broader commitment to digital sustainability. The site is lightweight, fast, and minimal, with optimized infrastructure and minimal use of third-party scripts, heavy media, or unnecessary animations.

A philosophy of digital frugality

This A rating is no accident—it’s the result of conscious technological choices:

• A hash-only certification system (no file transfer)
• A low-energy blockchain (Algorand)
• Eco-conscious French hosting (Scaleway)

Less CO₂, more positive impact

This recognition confirms that technology and ecology can go hand in hand. At CertifiK, performance is measured not just in speed or security, but also in carbon efficiency.
