Core Viewpoint - The Milan-Cortina d'Ampezzo Winter Olympics in 2026 emphasizes sustainability as a core principle, addressing climate challenges and learning from the successful experiences of the 2022 Beijing Winter Olympics [1][5]. Technological Empowerment - The event will utilize advanced technologies for venue construction and post-event utilization, inspired by the "green legacy" of the Beijing Winter Olympics [1]. - The adoption of carbon dioxide transcritical direct cooling ice-making technology from Beijing aims to reduce carbon emissions to nearly zero, with further optimizations for low-carbon construction [2]. Legacy Rebirth - The Milan Winter Olympics aims to tackle the issue of post-event venue idleness by reusing existing facilities, reducing new construction by 60% [3]. - The main torch design will transform into a public art installation post-event, and the athletes' village will be designed for direct conversion into community housing [3]. Institutional Innovation - Milan has integrated green standards into its operational framework, including a carbon emission tracking system in the hosting contract, which quantifies the environmental costs of each venue throughout its lifecycle [4]. - The concept of "frugal hosting" from China has been localized in Milan, incorporating furniture rental and modular designs to promote resource recycling [4]. Addressing Challenges - The venue layout for the Milan Winter Olympics is more dispersed, with 15 venues located in distant areas, aimed at protecting the original landscape while adhering to new hosting norms related to climate change [4]. - Despite concerns about preparation progress, all core facilities are reported to be ready, with only final cleaning and finishing tasks remaining [4].
