As audiences expect more spectacular live shows, stadiums face pressure to reduce their environmental impact. Paris La Défense Arena, Europe’s largest indoor venue, is implementing sustainable measures like energy-efficient lighting, waste sorting, and rainwater collection. However, challenges remain, particularly in addressing audience transportation emissions. Experts suggest that venues focus on in-house sustainability efforts, such as renewable power, waste management, and promoting low-carbon food options, while advocating for improved public transportation connectivity.
