Green Key


Like other national and international ecological labels, Green Key brings recognition to those tourist facilities that demonstrate improvements towards the environment through the establishment of adequate environmental measures in their facilities, which contributes to the quality of life of the community and the promotion of local culture. Green Key is also a great marketing tool that helps attract more customers and groups looking for hotels that are eco friendly. Since it focuses on environmental education seeking to create a change in mentality in the population. Compared to other environmental certifications, its cost is very low. In addition, OPAS through its consultants can provide individualized workshops for each property and develop educational tools to assist in meeting the criteria.

Green Key… International eco-label for tourist facilities

Green Key is an annual voluntary certification for tourist facilities that aim to contribute to the prevention of climate change and sustainable tourism by granting and promoting appropriate environmental actions.

It is intended to change the practices and behaviors of tourism stakeholders, including companies, authorities, guests and local communities, and to participate in increasing their responsibility towards their own environment. Most environmental certifications or “ecolabels”, as in Green Key, share management criteria and technical issues. They all ensure the same level of environmental content. But the Green Key is the only one that focuses on environmental education. Making demands on staff, clients and suppliers in participation and involvement in the program. The national operators of each country, with the advice of a steering committee, are in charge of the activities and administrative aspects of the certification. Periodically, each company receives visits from the national operator to verify that the certification standards are in compliance. In turn, from time to time, members of Green Key International visit the countries and properties that have the certification to make sure that they comply with the international standards of the program.

What are they focusing on?

The criteria focus on environmental management, technical requirements, and the participation of customers, staff and suppliers. It also covers fields such as water, waste, energy, environmental management, the use of chemicals, open spaces, food and beverages.

How does it work?

The award is requested voluntarily and is awarded once a year in which audit visits are made to verify that all criteria are met. Facilities have to demonstrate that they have adopted ecologically sound practices and strategies within their operations in accordance with standardized international criteria, which are mandatory in each country, as well as more specialized national criteria, which are adjusted to national legislation, infrastructure and culture.

Why participate?

Sustainable tourism is good for business, not only does it represent corporate social responsibility, but it also represents savings in operating costs. With the implementation of good environmental practices it is possible to transform the facilities into sustainable facilities. Today this is very significant since we live in an economy that focuses only on profit without caring about the environmental repercussions. Many hotels, small and large chains around the world have been adopting a green economy with environmentally sound practices
