A public debate is promoted by a citizens' committee in the Italian region of Mont Blanc, in order to promote Aosta as the host of the Winter Olympics in 2026 or later. The idea was to build support among the citizens and promote the Games from the bottom up, to build a consensus supporting the effort. The Aosta Valley region's economy is mainly based on winter sports. Starting from 1970s the main winter resorts hosted world events: Courmayeur hosted a round of the 1977 Alpine Skiing World Cup, Cervinia a round of the 1978 Alpine Skiing World Cup, La Thuile a round of the 2016 Alpine Skiing World Cup and bobsleigh's FIBT World Championships 1971, Cogne a round of the 1984-85 FIS Cross-Country World Cup and a round of 2006-07 FIS Cross-Country World Cup and Fénis hosted in the 1986 FIL World Luge Natural Track Championships. In 1991, the city made a bid for the 1998 Winter Olympics but lost to Nagano, so a 2026 bid would be the city's second attempt. In 1993 Aosta hosted the first edition of the winter European Youth Olympic Festival and in 2010 it hosted the first edition of the Winet Military World Games. The Aosta bid was cancelled when it was announced that the city of Milan will be the host city of the 134th IOC Session to decide the host city, and IOC regulations state that no bid from a country is allowed when the IOC session is in the same country.
