Data Quality
How venues are verified before inclusion
National operator lists first
Each dataset begins with the official certified sites list published by ADEAC (Spain) or ABAAE (Portugal), cross-referenced against the Green Key Global certified sites map.
Venue-level verification
Each venue's own sustainability pages, annual reports, and certification documentation are checked to confirm active certification status, year, and key sustainability features.
Annual review each June
Green Key certificates are annual — a venue present in one edition may not renew. Venues are removed or flagged if certification lapses or cannot be confirmed.
No false certification claims
Venues holding only EarthCheck, Biosphere, ISO 14001, or LEED without Green Key are not included unless dual certification with Green Key is explicitly verified.
