3HB Hotels has renewed its Green Key certification across all of its hotels for 2026, reinforcing the group’s commitment to sustainability, responsible resource management and the promotion of more sustainable tourism.
This international recognition confirms the consistency of 3HB Hotels’ environmental strategy and its ongoing investment in adopting best practices that help minimise the environmental impact of its operations, while ensuring high standards of quality and comfort for its guests.
The renewal of the Green Key certification recognises the work carried out by 3HB Hotels’ teams in implementing responsible management practices, promoting the efficient use of resources, reducing environmental impact, and fostering a culture of shared responsibility among employees, guests and partners.
This approach is reflected in the continuous improvement of operational processes through the implementation of solutions that optimise the use of energy, water and other resources, balancing operational efficiency with service excellence.
The renewal of the certification across all properties reflects a long-term commitment to sustainability by embedding these principles into day-to-day operations and strengthening a strategy built on innovation, environmental responsibility and continuous improvement.
This recognition is also the result of the dedication of the teams, whose work has ensured compliance with the demanding criteria established by the Green Key programme while consolidating best practices across all areas of the business. More than recognising a set of implemented measures, this certification reflects an organisational culture built on responsibility, consistency and continuous development.

In Portugal, the programme has been coordinated by the Associação Bandeira Azul de Ambiente e Educação (ABAAE) since 2006. In 2026, as Green Key celebrates its 20th anniversary in the country, 446 tourism establishments were awarded the certification — the highest number ever recorded — placing Portugal fifth worldwide in terms of certified establishments.
Today, Green Key certification is an internationally recognised benchmark for travellers seeking hotels committed to responsible environmental practices. For 3HB Hotels, it represents the continuation of a long-term sustainability strategy focused on the efficient use of resources and the continuous improvement of environmental performance, contributing to more responsible tourism and a high-quality guest experience across all its properties.
Just for you!
