Columbus-based TSYS has started turning the lights off in some of its Riverfront campus offices three days a week to conserve energy and money.
The lights-off campaign stemmed from the credit card processor's green committee, which was established last summer to find ways the company could be more environmentally-friendly.
TSYS began turning the lights off every Friday last fall in areas with windows that could let in natural light, said Cyle Mims, TSYS spokesman. They didn't implement it as much during the darker winter months. This summer, TSYS upped its lights-off days to three.
Not all lights are turned off, Mims said, and employees can request some areas be well-lit if they're having sight problems.
Never miss a local story.
"It's not mandatory, it's voluntary," Mims said.
To become more environmentally-friendly, TSYS has also increased its paper and plastic recycling at all their facilities in Columbus. The company participates in a rideshare program as well.
