What's Happening?

The Winter Olympics, traditionally held in regions with reliable snowfall, are facing new challenges due to climate change. Rising global temperatures are reducing the number of cities capable of hosting the Games with natural snow. According to a study funded by the International Olympic Committee (IOC), by mid-century, the number of suitable host cities could be halved. As a result, the reliance on artificial snow production has increased, exemplified by the Beijing 2022 Games, where nearly all competition snow was machine-made. This shift requires significant infrastructure, including reservoirs and electricity grids, which can strain local ecosystems. The IOC is promoting sustainability, aiming for 100% renewable electricity for snow production at the Milano Cortina 2026 Games, but the structural dependence on artificial snow remains a concern.

Why It's Important?

The increased reliance on artificial snow poses several risks. It can alter local hydrology and stream flows, especially in fragile alpine ecosystems. The infrastructure needed for snowmaking can strain resources in regions already facing water stress. Additionally, artificial snow can be denser and icier than natural snow, increasing the risk of injuries for athletes. Smaller national federations may struggle with the financial burden of accessing snowmaking facilities, impacting their ability to compete. The environmental and economic costs of building new infrastructure for the Games also raise concerns about sustainability and legacy use.

What's Next?

The Winter Olympics are adapting to a warming climate by increasing the use of artificial snow. The IOC has set sustainability benchmarks for the Milano Cortina 2026 Games, including the use of renewable energy for snow production. However, the long-term viability of the Games depends on addressing the ecological limits of artificial snow reliance. The IOC is considering a rotational system of climate-reliable venues to reduce the need for new infrastructure every four years, which could help mitigate environmental impacts.

Beyond the Headlines

The IOC is emphasizing sustainability and climate responsibility, encouraging the use of renewable energy for snow production. Host cities are advised to consider legacy planning to ensure infrastructure is used beyond the Games. Athletes and federations should prepare for the challenges posed by artificial snow, including potential safety risks and increased training costs.
