Ecosia scores 71/100 (Leading practice) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Ecosia 1st of 809 companies scored, and 1st of 75 in SaaS / Digital Services.
Ecosia is structurally sound: a ClimatePartner-audited 102t operational footprint (stable, not yet on an evidenced reduction trajectory), 200% renewable energy ownership, and all profit reinvested into ecosystem restoration via binding steward-ownership. Weaknesses are documentation gaps — no Scope 3 breakdown, AI energy unquantified, no TCFD/CSRD disclosure — and dependency on Microsoft Bing infrastructure it does not control.
