How is Ecosulis's SINK score calculated?
Same ten questions for every company. No private weighting.
SINK = (0.3 × Base + 0.7 × Performance) × ScaleWhat evidence is Ecosulis's score based on?
15 sources used in this assessment. All publicly available. Each row shows which of the ten questions it informed.
33% of them were published by Ecosulis itself; the rest come from independent sources.
Ecosulis's Scope 3 covers only the categories required for public contracts. It leaves out purchased goods and subcontracted works, which are material for a habitat-creation contractor. We apply the cautious 0.70x size deduction we use when a company's emissions are incomplete (owner ruling 2026-11-06).
10 of 15 sources are independent of the company.
