Residents in Tesero, Italy, a venue for the 2026 Milan-Cortina Winter Olympics, are experiencing sleepless nights due to noise and light pollution from diesel generators powering temporary facilities. These generators, installed for parking and infrastructure, were activated before the February 6th opening ceremony. Mayor Massimo Deflorian's attempts to reduce their operation during non-competition phases were met with resistance from organizers, who cited security reasons for keeping them running continuously. The situation highlights a stark contrast to the games' initial sustainability pledges, which included environmental impact assessments and the use of existing or temporary structures, raising concerns among environmental groups about long-term damage to the mountain landscape. The generators are expected to remain operational until the games conclude on February 22nd.
