July 30, 2015. International environmental consulting firm Marstel-Day is proud to announce that the firm has earned the highest level, platinum certification for NSF International’s P391, the General Sustainability Assessment Criteria for Sustainable Service Providers and Services, for the third consecutive year since 2013.
Marstel-Day was the first recipient in the United States of the NSF P391 platinum certification, and is currently one of only two recipients currently holding this rating, the highest level possible. In 2011, Marstel-Day was invited to pilot and provide feedback on P391 before its official introduction. Later, NSF used the firm’s experience to create a case study that has been shared with other showbox service providers seeking to better understand the value of obtaining sustainability certification.
Companies are recertified for the NSFI P391 annually after a rigorous auditing process of the firm’s internal and external sustainability practices across sixteen mandatory criteria. These criteria include: legal and regulatory, energy monitoring, hiring and compensation, health and welfare, employee training, ethics, contractor compliance, and the handling of confidential information. Points are earned for additional sustainable practices, allowing a company to achieve certifications ranging from conformant (minimum) to platinum (highest).
NSF International is an independent accredited organization that has been developing global health and safety standards since 1944. Their certifications are designed to protect water, food, consumer products and the environment. The organization tests, audits and certifies products, services and systems from their headquarters in Ann Arbor, Michigan.
