All HI (Hostelling International) Hostels that fulfill certain criteria in environmental work are granted permission to be called Green Hostels and to use the Green Hostel environmental logo. This classification should make it simpler for customers to make a greener choice and also encourage hostels to constantly work on adapting and improving their green quality standards. The references used (for classification) are composed from the HI Iceland general quality standards, that all Icelandic hostels must fulfill. To gain the Green Hostel logo the hostels have to fulfill additional environmental criteria.

It is important to note that this is not a recognized environmental certification but standards that HI Iceland decides and supervises.
