President and CEO of Green Seal, Dr. Arthur Weissman, Leaving After 24 Years of Dedicated Service

Vice President of Certification, Mary Swanson, to Serve as Interim President

WASHINGTON, D.C. August 28, 2017 – After two decades at the helm of Green Seal, the nation’s foremost environmental certification body, Dr. Arthur B. Weissman has announced that he will be leaving the organization on September 30, 2017. To ensure a smooth transition, Green Seal’s Vice President of Certification, Mary Swanson, will serve as Interim President effective October 1 until the next President assumes his or her responsibilities. Lochlin Partners, a McLean, VA-based firm, has been retained to lead the nationwide search.

“It has been both a pleasure and a privilege to have worked at Green Seal for the past twenty-four years helping to create the green economy,” Dr. Weissman said. “Although I am stepping down as President and CEO, I plan to continue my life-long effort to help protect and preserve the environment in other capacities in the years ahead.”

“Arthur leaves a strong legacy of service to the organization and dedication to the vision of a sustainable environment and a green economy,” said Green Seal Board Chair, Joanne Fox-Przeworski, Ph.D. “We are all grateful and will honor his legacy by building on the foundation he has established. We wish him all the best in the years ahead.”

Dr. Weissman joined Green Seal in 1993 as its Vice President of Standards and Planning, and became President and CEO in 1996. He served as founding Chair of the Global Ecolabeling Network from 1994-1997, and as international convener for ISO 14020 guidelines for environmental labeling. Prior to joining Green Seal, he was responsible for developing national policy and guidance for the Superfund program at the U.S. Environmental Protection Agency, and also served in the U.S. Senate as a Congressional Science Fellow and worked for The Nature Conservancy. He is the author of In the Light of Humane Nature: Human Values, Nature, the Green Economy, and Environmental Salvation, published in 2014.

“The strides we have made at Green Seal would not have been possible without the commitment, hard work, and dedication of our valued clients, partners, and staff,” Dr. Weissman said. “Our programs continue to grow, and Green Seal is well-positioned to be an influential force greening the economy for decades to come.”

Human Resources: Value Creation

Businesses must evolve to stay competitive and this is also true of employment positions within those organizations. In the hotel industry, for example, the role that HR professionals perform continues to broaden and expand. Today, they are generally responsible for five key areas - government compliance; payroll and benefits; employee acquisition and retention; training and development; and organizational structure and culture. In this enlarged capacity, HR professionals are no longer seen as part of an administrative cost center, but rather as a member of the leadership team that creates strategic value within their organization. HR professionals help to define company policies and plans; enact and enforce systems of accountability; and utilize definable metrics to measure and justify outcomes. Of course, there are always new issues for HR professionals to address. Though seemingly safe for the moment, will the Affordable Care Act ultimately be repealed and replaced and, if so, what will the ramifications be? There are issues pertaining to Millennials in the workforce and women in leadership roles, as well as determining the appropriate use of social media within the organization. There are new onboarding processes and e-learning training platforms to evaluate, in addition to keeping abreast of political issues like the minimum wage hike movement, or the re-evaluation of overtime rules. Finally, there are genuine immigration and deportation issues that affect HR professionals, especially if they are located in Dreamer Cities, or employ a workforce that could be adversely impacted by federal government policies. The March Hotel Business Review will take a look at some of the issues, strategies and techniques that HR professionals are employing to create and sustain value in their organization.
