Canonical: https://ecomark.app/site/proton.me Latest EcoMark · Algo v4 # proton.me This grade belongs to proton.me. It is based on a bounded sample of up to 5 connected public pages plus public evidence. It is not a grade for any one page.

EcoMark puts the lowest-scoring areas first, so the next step is obvious. 1 efficiency ### Reduce resource and third-party requests by consolidating assets and removing unnecessary integrations. Lighter pages consume less bandwidth and device work and remain usable on slower connections. 2 sovereignty ### Avoid concentrating most third-party delivery in one provider ecosystem. A more portable and less concentrated stack gives organisations more control over technology and jurisdiction. 3 responsibility ### Publish sustainability evidence, consider carbon.txt, and use independently verified green hosting where practical. Transparent, secure defaults make digital impact understandable and give visitors meaningful choices. Breakdown ## Where the score comes from. Efficiency 55 #9 of 10 5 connected pages · ~620 KB measured/page · 0 KB JavaScript/page · 101 resource references/page · 90% sampled assets cacheable.
