Green Key





Rosa Viana Lda, manager of Casa Viana Guesthouse, assumes the commitment and responsibility to reduce its environmental footprint, adopting a policy of Good Environmental Practices and seeking to be an example in the community where it operates. We are aware that this is continuous work, which is why we make the greatest efforts so that we walk together towards an increasingly cleaner future, thus also complying with the Sustainable Development Goals of the United Nations 2030 Agenda.

We are a Green Key venture

The “Green Key” program is an international award that promotes Sustainable Tourism in Portugal through the recognition of tourist establishments, local accommodation, campsites and restaurants that implement good environmental and social practices, that value environmental management in their establishments and that promote Environmental Education for Sustainability.
