Neo-futurism was in part revitalised in 2007 after the publication of "The Neo-Futuristic City Manifesto" included in the candidature presented to the Bureau International des Expositions (BIE) and written by innovation designer Vito Di Bari (a former executive director at UNESCO), to outline his vision for the city of Milan at the time of the Universal Expo 2015. Di Bari defined his neo-futuristic vision as the "cross-pollination of art, cutting edge technologies and ethical values combined to create a pervasively higher quality of life"; he referenced the Fourth Pillar of Sustainable Development Theory and reported that the name had been inspired by the United Nations report "Our Common Future".
