Where the evidence comes from

What evidence is NOS Comunicações's score based on?

9 sources used in this assessment. All publicly available. Each row shows which rubric questions it informed.

NOS, S.G.P.S., S.A. — Portuguese telecommunications & media group (nos.pt). Prior FAILED runs were validation failures (dead URL, then thin/aggregator sourcing), NOT an API/quota error. INDEPENDENT SOURCES (2026-08-20 review): added EDP PPA, CDP A-List (ECO/SAPO), FT Climate Leaders (Ambiente/Telecompaper), Sustainalytics — all corroborate the existing scoring. CAVEAT: 'SBTi-validated' target wording could not be confirmed directly on the SBTi dashboard (JS-gated); the target NUMBERS are independently corroborated.
