When was the last time you saw a truly dark sky? For most city dwellers, the answer is measured in years, if not decades.
Light pollution has rendered the night sky nearly invisible across much of the developed world, and Amsterdam is no exception. Where a naturally dark sky reveals up to 6,000 stars, light-saturated Amsterdam typically offers just a few hundred. Now ARTIS, the Dutch capital's historic zoo, has become the first location in a European capital city — and the first zoo anywhere in the world — to earn Dark Sky certification, recognizing its efforts to protect the night and combat light pollution.
The initiative addresses a crisis that's both pervasive and overlooked. The Netherlands ranks among the most light-polluted countries globally, with artificial lighting in urban areas increasing by 5 to 10 percent annually. According to DarkSky International, "In the United States and Europe, 99% of the public can't experience a natural night." This relentless illumination disrupts biological rhythms, disorients wildlife and affects human health, too.
ARTIS conducted a comprehensive inventory of its outdoor lighting, removed or modified unnecessary fixtures and implemented sustainable measures to reduce energy consumption. The result is visible from the air: viewed at night, Amsterdam appears as a sea of light punctuated by one conspicuous dark spot — the zoo. "Even in the heart of a major city, nighttime darkness can be protected," says Savitri Groag, ARTIS's sustainability coordinator. The zoo now hosts evening events where visitors can experience the power of darkness and rediscover the stars.
TREND BITE
Light pollution is widely acknowledged yet rarely prioritized. But smart brands are recognizing that the spaces they occupy – storefronts, offices, warehouses, parking lots – represent underutilized capacity for creating positive change. This is CAPACITY CAPTURE in action: finding creative ways to tap into underutilized resources for the good of society and the planet. In this case, that resource is darkness.
By rethinking when and how artificial lighting is deployed, organizations can support biodiversity, improve human health and restore a sense of wonder that urban dwellers have nearly forgotten. Other brands: could you position yourselves as custodians of the night? And more broadly, which other neglected resources could unlock value that extends far beyond your bottom line?
