Winners announced in Green Workplace Challenge

A friendly environmental competition among 50 Western Pennsylvania companies, nonprofits and other organizations resulted in $1.5 million in energy savings and 436 fewer tons of waste heading to landfills over the past year, organizers said.

The Green Workplace Challenge, which wrapped up its third installment with an awards ceremony at the Andy Warhol Museum Wednesday evening, encouraged participants to reduce energy and water use, cut pollution and get more employees involved in environmentally friendly work. Participants earned points in the yearlong competition by taking certain steps, such as putting in bike racks, conducting energy audits or installing more efficient office equipment.
