Orion said Feb. 15 that it had achieved a Gold rating from EcoVadis, an independent assessor of a variety of sustainability metrics.
The company's overall score also improved over last year, increasing from 72 to 77—only one point away from a Platinum rating.
The score puts Orion in the 99th percentile of companies assessed by EcoVadis.
"The way Orion was able to jump five points in one year and reach the top 1 percent of companies shows how the many improvements we have made can add up to a big change," Orion CEO Corning Painter said. "We are so close to Platinum now and will continue to strive for that goal as we deliver sustainable solutions to our customers."
