To mark the MS Tûranor PlanetSolar solar-powered boat’s first-ever visit to Paris, on September 12, 2013 the Akuo Foundation organized, in partnership with the R20 and Le Monde des Fondations & du Mécénat, a “dîner de l’écologie positive” (positive ecology dinner). In the extraordinary surroundings of the Orangerie greenhouse in the Parc André Citroën in Paris, this positive ecology dinner brought together more than 300 people and enabled over 30 000 euros to be raised to finance three emblematic positive ecology projects.
