LONDON—Adagio has reached a new milestone this year in its Green Key certification process, which began in 2025. With 20 new certified properties in 2026, the network now boasts 78 aparthotels—representing over 60 percent of all Adagio properties. This significant growth illustrates the rapid development of a more responsible hospitality model, activated in the heart of European cities. This momentum is part of a long-term strategy: Adagio aims for 100 percent Green Key certification, confirming the commitment of Europe’s leading aparthotel operator to increased sustainable hospitality in urban centers.
The Green Key ceremony, which officially recognizes certified establishments in France, took place recently in Strasbourg, marking a significant event for all stakeholders in sustainable tourism.
This year, 18 newly certified aparthotels in France received the Green Key label, confirming the brand’s commitment to sustainability within the country.
Internationally, 27 certified sites are spread across 10 countries, including Germany, the United Kingdom, Belgium, the Netherlands, Switzerland, as well as the United Arab Emirates and Qatar.
This initiative extends beyond company-owned properties. Of the 78 certified aparthotels, 58 are managed by Adagio, 14 are franchised, and 6 are master franchised, reflecting the growing mobilization of the entire network around shared environmental standards.
Measurable Results Closely Aligned with Real-World Use
A leading international sustainable tourism label for tourist accommodations, Green Key is based on a demanding approach structured around seven key areas of action: environmental policy, customer awareness, energy, water and waste management, responsible purchasing, and living environment.
At Adagio, this certification process translates into concrete and measurable actions, implemented at the local level:
- Four percent reduction in energy consumption per occupied apartment.
- Water savings of up to 5 percent per occupant at French sites.
- More than 20 tons of biowaste valorized/processed through local partnerships.
- More durable household appliances, with increased use of repair and the circular economy.
- Initiatives promoting urban biodiversity and local community engagement.
Towards a Sustainable Standard for Urban Aparthotels
The Green Key certification is one of the cornerstones of Adagio’s CSR strategy, built around its commitment to “Acting for the Transition of Cities.” Building on current momentum, this movement will continue to grow, with confirmation of 20 new certifications in 2026.
Beyond simply obtaining the Green Key label, the brand affirms its commitment to making it an operational standard, integrated from the initial design of new openings and implemented across its entire portfolio.
“The increasing number of Green Key certified sites reflects the concrete commitment of our teams and the coherence of our CSR strategy,” says Virginie Barboux, Senior Vice President Client & Marketing, Adagio. This label is both a demanding framework and a powerful tool for mobilization. It allows us to move forward in a structured, measurable, and collective way toward more responsible hospitality, serving cities and their inhabitants.”
On the ground, this approach and the recognition of the efforts undertaken are a great source of pride for the teams.
“The Green Key initiative has allowed us to structure our actions, better involve our employees, and make our commitment more visible to our clients,” says Yoann Angot, General Manager, Adagio Access Le Havre Les Docks. “It’s demanding work, but deeply unifying, and it gives meaning to our daily work.”
