Commitment to Renewable Energy
The organizing committee for the 2026 Milan Cortina Winter Olympics has pledged that nearly all electricity used during the Games will come from renewable sources. This initiative aims to address the significant energy demands of the event, which traditionally contribute to greenhouse gas emissions. Italy's largest electricity provider, Enel, has committed to supplying 85 gigawatt-hours of certified renewable electricity for the Games. To ensure this, Enel has purchased "guarantee of origin" (GO) certificates, which verify that the electricity is generated from renewable sources. In instances where temporary power generation is necessary, hydrotreated vegetable oil will replace traditional diesel fuels.
Broader Implications of Clean Energy Initiatives
The organizing committee views this commitment as an opportunity to demonstrate the viability of cleaner energy solutions for large-scale events. They hope that the steps taken for the 2026 Games will inspire future host cities and contribute to a broader shift towards sustainability in major events. Julie Duffus, head of sustainability at the International Olympic Committee (IOC), emphasized the importance of innovation in sustainability and reducing the overall carbon footprint of the Games.
Criticism of the Sustainability Efforts
Despite the ambitious goals, some experts express skepticism regarding the actual impact of these initiatives. Matteo Villa, from the Italian Institute for International Political Studies, noted that while promoting the event as sustainable is beneficial, it does not necessarily make Italy cleaner or more renewable. He highlighted that the overall sustainability of the Games is contingent upon Italy's entire energy infrastructure, which still relies heavily on fossil fuels. Enel's preliminary data indicates that approximately 73% of its electricity production in 2025 was carbon-free, yet a significant portion still came from gas-fired power plants.
Emissions from Transportation and Accommodation
A major challenge for the organizers is addressing emissions that are beyond their direct control, particularly those associated with transportation and accommodations. The organizing committee estimates that the greenhouse gas emissions from the Games will be equivalent to those produced by 4 million gasoline-fueled cars traveling from Paris to Rome. The largest contributors to the carbon footprint are activities indirectly related to the Games, such as spectator travel and lodging. Air travel, in particular, is a significant source of emissions due to the carbon dioxide released from burning jet fuel.
Future Considerations
Karl Stoss, chair of the Games' Future Host Commission, has suggested that future events may need to consider reducing the number of sports, athletes, and spectators to mitigate environmental impacts. This reflects a growing concern among athletes, including Team USA skiers Lindsey Vonn and Mikaela Shiffrin, about the effects of climate change on winter sports and the sustainability of hosting such events.
