Green Key Criteria

Establishments awarded with the Green Key certification meet a set of high standard environmental requirements. The Green Key criteria and their explanatory notes are available to all interested parties and can be downloaded below. We have developed criteria and explanatory notes for six Green Key categories (hotels and hostels, campsites and holiday parks, small accommodations, conference centres, restaurants and attractions) covering the same 13 criteria areas.

Green Key criteria  has been developed for the following categories: hotels and hostels, campsites and holiday parks, small accommodations, conference centres, attractions and restaurants.

Here you can download the criteria and explanatory notes for each of the different categories:

The criteria and explanatory notes for hotels and hostels have received 'GSTC-recognition' status.

Most criteria are imperative and must be in compliance, while other criteria are guideline in that an increasing percentage of guideline criteria must be met depending on the years of involvement in the Green Key programme.

It is possible for the Green Key national programmes to strengthen/add criteria in conjunction with the international criteria.
