Winter Games local weather targets conflict with environmental actuality, placing sustainability claims to the take a look at

The Winter Olympics and Paralympics have, for many years, been a celebration of snow, chilly and mountains — a worldwide showcase for sports activities constructed on dependable winter circumstances. 

But as temperatures rise and snowfall turns into tougher to rely on, that basis is much from strong — and environmental consultants say Olympic organizers are nonetheless overselling how “sustainable” the Games could be.

With Italy set to host the subsequent Winter Olympics in simply weeks, adopted by the Paralympic Games in March, that rigidity is already shaping planning selections, infrastructure selections and local weather guarantees, and exposing how onerous these guarantees are to maintain.

The International Olympic Committee (IOC) has acknowledged the issue. A 2024 research it commissioned discovered that solely about half of earlier Winter Olympics host cities would nonetheless be chilly sufficient to host the Games by the 2050s.

A November 2025 ski-resilience index monitoring snow reliability ranked many resorts as more and more susceptible, with Cortina d’Ampezzo, the Alpine city and primary web site of the upcoming Games, squarely within the center. Researchers say that raises doubts about what occurs as soon as the Olympic highlight fades.

Still, the IOC insists its local weather targets stay on monitor.

It goals to chop carbon emissions by 50 per cent by 2030 and now requires host cities to rely nearly totally on present or short-term venues.

Snow competitors websites, it says, should stay “climate reliable” — which means they must be chilly and snowy sufficient to carry occasions with out extreme technical intervention — till not less than mid-century.

Temperatures within the Italian Alps are already above long-term averages. February highs in Milan can attain 10.2 C. In Cortina, the typical is now about 4.2 C. Natural snowpack, which continues to be central to honest competitors, has turn into more and more hit-or-miss. Artificial snow and refrigeration are now not backups, however a necessity.

Organizers say Italy has a strong historical past of sustainability on the centre of planning massive occasions. 

Gloria Zavatta, the sustainability and influence director for the upcoming Winter Games, factors to the 2006 Turin Olympics and the 2015 Milan Expo as early makes an attempt to measure and handle emissions. 

These occasions, she stated, laid the groundwork for Milano-Cortina’s strategy, which follows the ISO 14064 worldwide normal for greenhouse-gas reporting and commits organizers to producing a full CO2 stock by the tip of 2026, with the aim of offsetting these emissions.

Travel, lodging greatest blindspots

The accounting, although, has main limits. It covers what organizers instantly management — venue vitality use through the Games, the Olympic transport system and short-term infrastructure. But it excludes what is commonly one of many greatest sources of emissions at main sporting occasions: spectator journey.

“We are sending [spectators] and international federations some guidelines, inviting them to use the most sustainable way of transport, to reduce flights and use of single vehicles, to use collective and public transport,” Zavatta stated. “But it’s not under our control.”

Zavatta stated the occasion offers an necessary alternative to boost consciousness about local weather change.

That argument doesn’t persuade everybody.

“I find it kind of comical that raising awareness among fans is the goal of an event with budgets this big,” stated Madeleine Orr, assistant professor in Sport Ecology on the University of Toronto. “The plan with the 2010 Vancouver Olympics was raising awareness on climate change. I mean, what are we doing? It’s 2026.”

Orr says latest Games present each how far organizers can push sustainability efforts and the place they hit a wall.

She factors to the Paris 2024 Summer Games because the closest any Olympics has come to assembly stringent sustainability standards, and says the Milano-Cortina Games will inevitably fall in need of that benchmark. 

But she additionally says even Paris overstated its achievements — selling itself as a “carbon positive” Games for 2 years earlier than retreating to “carbon neutral” after researchers challenged the declare.

“They were so obsessed with this narrative that they were sustainable and perfect that they sank themselves,” Orr stated. 

One of the researchers who challenged the Paris claims was Tiberio Daddi, a sports activities sustainability skilled and affiliate professor on the Institute of Management of the Scuola Superiore Sant’Anna in Pisa. He has labored with the International Ski Federation and the International Biathlon Union on life-cycle assessments of sports activities occasions.

Daddi says his findings present the largest impacts nearly at all times come from journey and lodging.

“With soccer, where large numbers of fans are travelling, the impact of travel can make up as much as 60 per cent of the overall footprint,” he stated.

Daddi says Olympic accounting ought to not less than try and estimate emissions from spectator journey, athlete and employees mobility, and logistics — from transport tools to powering world broadcasts.

He says  ISO 14064 is strong in concept however erratically utilized in apply. Carbon will get consideration. Waste, noise, visible impacts and biodiversity usually don’t.

“They should clearly state what they are including in their assessment and what they are not,” Daddi stated.

Reuse, renovations and inventive accounting

Orr raises comparable considerations about how Olympic organizers outline the time period “reuse.”

Organizers say 92 per cent of Milano-Cortina venues exist already, with solely two new buildings being constructed, each in Milan: the Olympic Village slated to turn into scholar housing after the Games, and the Santa Giulia enviornment for males’s hockey, deliberate as a live performance venue later.

But main renovations to present services aren’t totally mirrored in emissions totals.

“This is the kind of creative accounting Qatar was using with the FIFA World Cup,” Orr stated. “They said, ‘We built all these stadiums but they’re going to be used indefinitely, so we’re really only responsible for two weeks of that stadium’s emissions.’ And, well, no, actually. If the Winter Olympics didn’t exist, these renos wouldn’t have happened.”

Timing, she says, is a part of the issue. Sustainability planning for Milano-Cortina got here late, after key development selections have been already locked in.

Nowhere is that extra seen than on the controversial sliding centre within the Alpine city of Cortina, the place organizers emphasised reuse of the present Eugenio Monti luge monitor.

But critics — and there have been many in Italy — say the mission grew to become a near-total rebuild, beginning with the felling of a whole lot of mature larch timber to create space for the broader development footprint.

Early tenders to assemble the advanced reportedly failed, and prices climbed to effectively over €100 million, or $160 million Cdn. 

Even although the ice chute was accomplished in report time, considerations stay. Sliding tracks want energy-intensive refrigeration and yearly upkeep.

With a tiny variety of world luge, bobsleigh and skeleton athletes, many have identified the venue dangers turning into a white elephant — costly to run and barely used lengthy after the Games finish.

Zavatta stated the choice to construct the sliding centre rested with the area, not by the organizing committee, and that utilizing an present monitor in Austria, an alternative choice floated, would have been troublesome to co-ordinate throughout borders.

Calls for a rotating Winter Games

Orr says the larger challenge stays.

“Huge international spectacles are antithetical to being sustainable,” she stated. “There’s no version of those events that are.”

That argument is now being echoed from contained in the winter sport group. 

International Ski and Snowboard Federation president Johan Eliasch has warned that rising prices, local weather strain and underused Olympic infrastructure are pushing the Winter Games towards a breaking level.

He is amongst these calling for a rotation mannequin, wherein a small variety of climate-stable venues take turns internet hosting. While no official checklist exists, websites usually talked about are Vancouver–Whistler, Calgary–Canmore, Salt Lake City–Park City, Utah, Lillehammer, Norway, and Sapporo, Japan.

Snowmaking, more and more important to the Winter Games, exhibits why the system is beneath strain.

Nemanja Dogo, govt gross sales supervisor at TechnoAlpin, which is operating about 90 per cent of snow supply operations for Milano-Cortina, says snow making is simplest when temperatures fall roughly between -6C and -2C, utilizing wet-bulb temperature — a mixed measure of air temperature and humidity — to find out whether or not snow could be produced in any respect.

“We’re always talking about the window when we can make snow, to not lose energy and efficiency,” Dogo stated.

Artificial — or “technical” — snow additionally has limits: a pure base of snow continues to be wanted to stabilize slopes and guarantee protected, honest competitors at Olympic scale. 

Producing that snow requires vital quantities of water, pushing many resorts to rely extra on saved provides, together with synthetic reservoirs that may additionally help different makes use of, from summer season water administration to firefighting.

As local weather strain builds, concepts for reshaping the Winter Games proceed to flow into. None provides a simple repair. 

What is evident, although, is that an occasion designed to showcase winter, snow and mountains is now preventing to breed these foundational circumstances — now elevating questions on how lengthy the mannequin can maintain.
