<\/div>\n\n\n\n

In an age where the stars seem to be fading from our night skies, local administrations are beginning to rethink public lighting to tackle an increasingly widespread issue: light pollution.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Often overlooked, this phenomenon disrupts the natural cycle of darkness, negatively affecting biodiversity, human health, and the quality of astronomical observations.<\/p>\n\n\n\n

<\/div>\n\n\n\n

A model project: technology and awareness<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

In this context, Asiago has launched an innovative public lighting redevelopment project, in collaboration with City Green Light<\/a><\/strong>, with a clear objective: to minimize light impact while maintaining safety and comfort for citizens.<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

Over 1.400 lighting points<\/strong> have been replaced, with warm 3,000 K LEDs<\/strong> installed\u2014and 2,200 K near the observatory\u2014to limit blue light emissions, the main cause of skyglow. Moreover, the new fixtures ensure zero upward light emission<\/strong>, thanks to carefully selected optics and photometers.<\/p>\n\n\n\n

<\/div>\n\n\n\n

But it’s not just a technical matter: the project includes smart systems<\/strong> that automatically halve the light output at midnight and sensors for dynamic adjustment based on the passage of people or vehicles. The result? A reduction of over 150 tons of CO\u2082 emissions per year<\/strong> and an estimated energy saving of up to 70%.<\/p>\n\n\n\n

Science at the service of cities<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

The fight against light pollution is also a cultural challenge. Lina Tomasella<\/strong>, PhD, from INAF \u2013 National Institute for Astrophysics, Padua Astronomical Observatory, highlighted that although the public sector has made progress, today 60\u201370% of light pollution is caused by private lighting<\/strong>, which is often beyond regulatory control.<\/p>\n\n\n\n

A replicable model<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

The Asiago project demonstrates that environmental protection and innovation can go hand in hand<\/strong>. City Green Light, a signatory of a protocol with the Italian Amateur Astronomers<\/a> Union and the International Dark Sky Association, is promoting this model in other areas as well.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Lighting where and when it is needed means restoring the starry sky to those who observe it, protecting nature, and improving life in our cities.<\/p>\n\n\n\n
