How do ice rinks impact the climate?

Ice rinks contribute to climate change by using hydrofluorocarbons (HFCs) in their cooling systems, which leak into the atmosphere as potent greenhouse gases, and through emissions from traditional diesel-powered Zambonis.

What are the challenges facing winter Olympic sports due to climate change?

Warming winters necessitate increased reliance on artificial snow production, which is resource-intensive, and the overall climate impact of ice sports must be addressed to preserve the foundation of these disciplines.

What sustainable alternatives exist for ice sports?

Sustainable solutions include cooling ice arenas with liquefied carbon dioxide instead of HFCs, using plastic-based synthetic ice surfaces to conserve water, and implementing energy-efficient upgrades like solar panels for rinks.

Indoor ice rinks leak potent greenhouse gases, impacting the planet.
Sustainable alternatives like plastic ice and CO2 cooling offer hope.

Ice Sports Melting: Climate Crisis Threatens Winter Games

The sustainability of ice sports, including figure skating, is under increasing scrutiny due to the growing impact of climate change. Warming winters have led to a greater reliance on artificial snow for major events, such as the 2022 Beijing Olympics, which used over 192 million gallons of water. The upcoming Milan Winter Games are also expected to require significant artificial snow production.

Indoor ice arenas contribute to the problem by using hydrofluorocarbons (HFCs), potent greenhouse gases that leak into the atmosphere during the cooling process. Traditional Zambonis, often diesel-powered, also emit pollutants like carbon monoxide and nitrous oxide. These factors highlight the need for ice sports to decarbonize to protect the planet.

Despite these challenges, advancements in sustainability are being made. The Beijing Olympics notably used liquefied carbon dioxide for cooling, reducing reliance on HFCs. The International Skating Union released sustainability guidelines in 2024 to promote greener practices.
