Sustonica is the first sustainability validation standard for short-term rentals globally. It offers a unique platform that streamlines auditing to vet vacation rentals using GPS-verified evidence. Properties must meet environmental and social standards to receive certification. The validation includes software, external verification by Bureau Veritas, a digital certificate, and a badge valid for one year. Aligned with SDG, ISO, GSTC, EU Ecolabel and Travalyst standards, Sustonica-validated properties appear in Booking.com's sustainability filter at Level 3+. It combats greenwashing through third-party auditing.
