The International Olympic Committee (IOC) will continue taking measures to cut costs for Olympic host cities in an effort to make future Games attractive to bidders, the organization's president Thomas Bach has said.
He added: "What is true is we have to continue our efforts, particularly with regard to winter sports, to be more flexible in order to reduce costs, avoid construction of sports facilities that have no legacy."
Bach's comments follow decisions by Austria's Graz, Switzerland's Sion and Japan's Sapporo to abandon their 2026 bids, reportedly due to concerns about costs and strong local opposition.
However Calgary's plans could be stymied by a non-binding plebiscite in November while Stockholm and the Italian candidacy are said to be struggling for political support.
Bach said demand to stage the winter and summer Games remained strong while several sports have shown interest in obtaining Olympic status.
"We have more than a dozen sports who would like to join Olympic programme," he said. "Quite a number of interested cities, big number of interested cities (for the 2032 summer Games). We should not be worried for the future."
