A hotel applies, documents each criterion, and is then visited on site. Certification runs for one year, so a hotel keeps it only by re-submitting evidence and passing another visit. It is the largest scheme in this catalogue and the one you will meet most often across Europe.
Green Key measures management practice, not carbon. A large hotel with a pool and air conditioning can hold the certificate while using far more energy per guest than an uncertified guesthouse down the road — it is being judged on whether it manages its resources deliberately, not on the size of its footprint. The scoring is also weighted towards documentation, so a hotel with good records can outscore one that quietly does better.
