One year ago, Small Luxury Hotels of the World (SLH) launched the Considerate Collection with 25 founding members of actively sustainable luxury hotels. Today the luxury brand adds a further five properties to the collection and celebrates 43 hotels, almost 40,000 trees planted in collaboration with TreeSisters, a first-of-its-kind partnership with new sustainability platform Weeva, and a collaboration with luxury amenities brand Vanity Group.
