Organizers of the Winter Games Made Clean Energy a Priority. Here's How They Did It

Why It Matters

Securing 100 % renewable electricity showcases how large‑scale events can drive clean‑energy adoption, but the broader carbon footprint still hinges on transportation and hospitality sectors.

Key Takeaways

• Enel provides 85 GWh renewable power via GO certificates.
• 100% of Games electricity sourced from certified renewables.
• New substations improve grid for local communities post‑Games.
• Travel emissions dominate the Olympics' carbon footprint.
• GO certificates face criticism for limited real‑world impact.

Pulse Analysis

The 2026 Milan‑Cortina Winter Games have placed clean electricity at the heart of their sustainability agenda. Enel, Italy’s largest utility, pledged to supply the entire event’s power demand—about 85 gigawatt‑hours—through certified renewable sources. To achieve this, the company purchased guarantee‑of‑origin (GO) certificates, each representing one megawatt‑hour of green generation, and cancelled them after use. This market‑based mechanism allows the Games to claim 100 % renewable electricity without building new plants, while also supporting Italy’s broader renewable expansion. Critics argue that certificates alone do not reduce actual emissions, but they provide a transparent accounting tool for large‑scale events.

Beyond the headline‑grabbing renewable claim, Enel invested in tangible grid upgrades across the Alpine region. New primary substations in Livigno and Arabba, together with reinforced distribution networks in Livigno, Bormio and Cortina, ensure reliable power delivery during the Games and leave a lasting infrastructure legacy for residents. The enhanced capacity will accommodate future demand for electric mobility, heating, and industry, effectively accelerating the region’s decarbonisation pathway. By embedding these upgrades into the event’s budget, organizers demonstrate how mega‑sporting spectacles can catalyse public‑utility projects that outlive the competition itself.

Nevertheless, electricity represents only a fraction of the Olympics’ overall carbon footprint. The organizing committee estimates emissions comparable to four million gasoline‑powered cars traveling from Paris to Rome, with the bulk stemming from spectator travel, accommodation and air freight. Addressing these indirect sources will require coordinated measures such as low‑carbon transport options, stricter venue capacity limits, and incentivised offset programmes. The Milan‑Cortina experience underscores a pivotal lesson for future hosts: clean power is necessary but not sufficient. Comprehensive sustainability strategies must integrate energy, mobility, and legacy planning to truly shrink the environmental impact of global sporting events.
