Winter Olympics Must Tackle Environmental Impact Before the Snow Runs Out | George Timms

Why It Matters

Rising climate risk and chronic cost overruns jeopardize the future profitability and public support of the Winter Games, forcing the IOC and potential hosts to rethink the event’s economic and environmental model.

Key Takeaways

• Only 8 of 21 past hosts remain climate‑viable by 2100
• Fossil‑fuel sponsors could raise Milano Cortina carbon footprint 40%
• Olympic budgets exceed forecasts by average 159% since 1960
• IOC abandoned OGI sustainability framework in 2017
• Ticket pricing and multi‑site hosting could cut travel emissions

Pulse Analysis

The accelerating loss of reliable winter conditions is reshaping the Olympic calendar. A New Weather Institute model predicts that by the end of the century only eight of the 21 cities that have ever hosted the Games will retain the cold needed for snow‑dependent events. Milano‑Cortina 2026 already illustrates the pressure: organizers must generate artificial snow, construct remote transport links and pour billions into new infrastructure. As temperature thresholds rise, the cost and logistical complexity of recreating winter environments are set to become the norm rather than the exception.

The International Olympic Committee’s sustainability track record remains patchy. The 2000 Olympic Games Impact (OGI) framework, with its 126 indicators, was scrapped in 2017 after host cities complained about its rigidity, leaving sponsors free to shape green narratives. A petition to bar fossil‑fuel backers prompted President Kirsty Coventry to promise ‘better conversations,’ yet a New Weather Institute report links Eni, Stellantis and ITA Airways to a 40 % rise in Milano‑Cortina’s carbon footprint—enough to melt 3.2 km² of snow. Meanwhile, academic studies show Olympic budgets overshoot forecasts by an average of 159 %, underscoring a chronic financial‑sustainability gap.

Experts argue that the IOC can cut emissions without overhauling its revenue model. Raising ticket prices for long‑haul travel and allocating seats geographically would discourage high‑carbon tourism, while most viewers already consume the Games via broadcast, which accounts for over 90 % of IOC income. Spreading events across multiple existing venues—rather than building new sites—could halve spectator travel distances and reuse infrastructure. Such reforms would improve transparency, lower public subsidies, and make future bids more attractive to cities wary of cost overruns and climate risk, preserving the Olympic brand in a warming world.
