Green Key certified establishments 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 fit into 13 categories, covering sustainable operations and environmental education. In each section there are a variety of Imperative and Guideline criteria.
