The EcoLabel is an initiative by the Ministry of Tourism and the Ministry for sustainable development and infrastructure, running since 1999. Ever since, the non-profit organization OekoZenter Lëtzebuerg has been in charge of the environmental counseling of both the businesses aiming to join the EcoLabel initiative and the businesses already part of the network.

Up to now, the certificate has been awarded to 37 accommodations, ranging from country lodgings, guest rooms and youth hostels to first class campsites and luxury hotels.

All of them have to meet a compulsory and rigorous set of criteria focusing on energy and water efficiency (e.g. efficiency of lighting and heating, use of renewable energies, insulation, purchase of energy efficient devices, low-consumption appliances), waste prevention and waste management, sustainable purchasing of office supplies (e.g. recycled paper), use of organic, locally grown and fair trade produce, support of public transport and cycle hire options for their guests, use of eco-cleaners etc.

There are over 60 individual measures the businesses have to meet to achieve a significant reduction of their environmental impact.

The businesses are first audited and then reassessed every three years by an independent auditor to ensure standards are maintained.
