To encourage the businesses of the territory of Fasano and Ostuni to undertake sustainability paths, the Dune Costiere Park provided the grant of using its own mark. The mark has to be displayed next to the logo of the business, and it can be granted, in compliance with a specific regulation, to those businesses in the Park area which respect the criteria of protection and conservation of the environmental and cultural resources they work in. The mark can be required by accommodation-tourist and catering businesses, farms and businesses specialized in the transformation of the agri-food products; businesses for the retail trade of agri-food products or local handcrafted products.
