SeloXIS is a Brazilian certification initiative focused on helping tourism businesses assess and strengthen their environmental, social, and governance (ESG) practices. Its certification serves tourism-related organizations, including hotels and events, and the site also lists suppliers, agencies, and real estate businesses among its areas of interest. Through an evaluation process, SeloXIS helps organizations review existing practices, identify opportunities for improvement, and set goals for more responsible operations.

The initiative promotes benefits for businesses, local communities, people, and the planet, with an emphasis on increasing positive impact and reducing negative impact. It offers a free assessment tool for organizations interested in understanding their ESG performance, alongside information about certified hotels and events. SeloXIS also shares articles and examples of sustainability in tourism, including responsible travel, environmental preservation, and continuous improvement. Testimonials from certified businesses describe the process as a way to engage teams, examine operations, and establish new targets. SeloXIS additionally features a climate guardians initiative and compensation services, connecting its work with broader efforts to support more sustainable tourism in Brazil.
