Sustainable Pittsburgh’s Green Workplace Challenge winners: How they did it Share this post The employers highlighted by Sustainable Pittsburgh‘s Green Workplace Challenge are varied; some are small companies, some are universities, some are municipalities. But the small steps each employer took to make their workplaces greener can add up to a serious impact. The friendly competition, now in its third year, ran from October 2014 for a full year and encouraged companies in the Greater Pittsburgh area to earn points in the competition by taking “green actions,” which ranged from using more energy-efficient light bulbs to encouraging carpooling. Each action was assigned a certain number of points, and everything, even the smallest act, could be counted toward the companies’ totals. In some instances, only a few points separated first place winners from runners-up.
