14 local organisations have earned UNESCO Biosphere Isle of Man accreditation.
It follows a series of business workshops on how to become more sustainable, which included topics such as energy use, dealing with waste, and helping nature and wildlife.
The Sustainable Mann sessions were run by UNESCO Biosphere Isle of Man along with the Department for Enterprise, Chamber of Commerce, Net Zero Isle of Man, UCM and the One World Centre.
Workshops will be delivered again this year, with more information to be announced in summer.
