Marstel-Day Achieves Highest Level of Certification as Sustainable Service Provider for Third Consecutive Year

Platinum Sustainability Certification  Marstel-Day is the 1st Firm in the U.S. to Receive the Highest Platinum Rating Fredericksburg, VA (May 1, 2015) – NSF International, the independent public health and standards development organization, has awarded a platinum-level sustainability certification to environmental management firm Marstel-Day, LLC, for the third consecutive year. Marstel-Day remains the nation’s only service provider to be awarded NSF’s highest level of certification to its P391 protocol for sustainable services and service providers.

“By achieving the NSF platinum-level certification, Marstel-Day is recognized for its commitment to sustainability and the environment,” Marstel-Day CEO and President Rebecca R. Rubin said. “Certification ensures oversight and gives credibility to measures we’ve always had in place.”

To achieve this certification, a company undergoes a stringent audit of 16 mandatory sustainability practices, plus up to 69 supplemental practices, encompassing areas such as environmental impacts (energy use and greenhouse gas emissions), labor impacts (health, safety, and employment), and social responsibility (community assessment).

Marstel-Day originally earned platinum certification in 2013 when it became the first company certified to NSF P391. Similar to the U.S. Green Building Council’s Leadership in Energy & Environmental Design (LEED) certification program, the NSF protocol is based on a point system, and offers certification at four levels, ranging from conformant to platinum.

At NSF’s request, Marstel-Day helped test-pilot the protocol even before P391 standards were officially introduced as North America’s first protocol to define sustainable services within the service industry. Later, NSF used Marstel-Day’s experience to create a case study to guide other service providers seeking to understand the value of sustainability certification.

NSF International develops global health and safety standards. Headquartered in Ann Arbor, Michigan, the organization tests, audits, and certifies services, products, and systems to protect water, food, consumer products, and the environment.
