The Milan-Cortina Winter Olympics were a resounding triumph, not only in terms of athletic achievement—with Italian athletes winning a record-breaking 30 medals—but also in terms of economic and environmental sustainability. According to the Milano Cortina 2026 Foundation's Sustainability, Impact, and Legacy Report, the Games had an overall positive economic impact of €5.3 billion, making them a strong engine of growth in the country. Specifically, this figure includes €1.1 billion in direct spending and €1.2 billion related to tourism generated in subsequent years. An additional €3 billion was allocated to infrastructure, with interventions designed to leave a lasting and tangible legacy in the territories involved. The total cost of the event was €5.9 billion, or around 0.3% of the national GDP, a low amount compared to previous editions of the Games. Public funds were used to finance 63% of the plan, while 66% of the investments were related to transportation and mobility, and the remaining 34% were for Olympic venues. On the environmental front, the strategy implemented was to mitigate the effects. To limit land use, 85% of the competition sites were existing or temporary, and all of the electricity was generated from certified renewable sources. Emissions from operations and construction totaled almost one million tons of CO₂ equivalent, with related activities and mobility accounting for 301,000 tons. Special attention was also made to resource management: snowmaking was optimized to safeguard mountain water supplies, with Livigno (Mottolino) being the largest production facility, with one million cubic meters. On the garbage front, 70% of all municipal waste was correctly recycled.
