Environment We work hard to minimize the environmental impact of our operations, products and services. From inside our doors to outside, Worthington is committed to being a good corporate citizen and environmental steward. A majority of our consolidated facilities are certified to ISO 14001 environmental management standards and ISO 45001 health and safety standards, while the remainder are self-certified to consistent standards. We have also empowered each employee to minimize waste and prevent pollution through the Company's GreenStar Initiative. Started in 2012, the GreenStar program is in place at all of our consolidated facilities. The primary objectives of GreenStar are to increase environmental awareness, drive continuous improvement and reward facilities for exceptional performance in environmental conservation and stewardship. Our locations are awarded "stars" for year-over-year improvements in five categories: continuous improvement, energy conservation, waste reduction, water conservation and regulatory compliance. Over 50 percent of our facilities achieved four and five star performance ratings in the last fiscal year.
