Assessment starts from a documented self-audit and is verified by InfraCert, with on-site checks at the higher levels. The tiering is the useful part: the level is on the certificate, so it distinguishes a hotel that has just started from one several cycles in.
The lower levels are reachable largely on documentation and policy, so a level-one certificate is a weaker signal than the badge alone suggests — the level matters more than its presence. It is also concentrated in German-speaking markets, so it is not comparable in coverage to Green Key.
