Company profile
researched Sep 2026Greena World operates a web platform for the hospitality and tourism sector that scores, verifies and publicises the sustainability performance of hotels and restaurants. Its workflow has three stages: an assessment that produces a "Greena Index" score, offered free at sign-up, which lets a business benchmark itself against other properties in the network and receive personalised feedback and resources aimed at cutting energy, water and operating costs; a verification stage in which sustainability claims are validated by third parties, positioned as a defence against greenwashing accusations and as preparation for forthcoming ESG regulatory requirements; and a communication stage in which the resulting profile and score are distributed through a guest dashboard, social media, on-property displays, the business's own website, booking platforms, and PR and media outputs such as templated press releases.
Property profiles present an overall score out of 100 described as the level of positive impact the business has on the planet and its people, broken down into Eco, Social and Wellbeing categories covering items such as elimination of single-use plastics, on-site renewable energy, recycling facilities, support for local artists and entrepreneurs, gender pay equality, staff skills training, green spaces, cleanliness and organic menu sourcing. The site also publishes a resource library with articles for operators on topics including eliminating single-use plastics, reducing hotel energy costs, eco-friendly cleaning and the use of plants in hospitality spaces. The corporate entity, GREENA WORLD LTD, is registered in England with a registered office at 128 City Road, London, and is classified under SIC codes for web portals and other business support service activities.

Traction
