More than 130 Louis Berger employees are now accredited ISI Envision® Sustainability Professionals

MORRISTOWN, New Jersey and WASHINGTON, DC — Louis Berger, a global professional services firm, has surpassed its goal to train and credential 100 of its professionals in the Institute for Sustainable Infrastructure (ISI) Envision® Sustainability Professional (ENV SP) program.

The corporation has accredited 132 ENV SPs across Louis Berger and its affiliate companies, Berger ABAM and Klohn Crippen Berger. An ENV SP is an ISI-credentialed practitioner who is trained to use the Envision rating system to address sustainability across the life cycle of all types and sizes of infrastructure projects.

"Our commitment to build a robust team of Envision accredited sustainability professionals reflects the strategic priority at Louis Berger to expand best-in-class sustainability and resiliency practices through our projects and in the communities where we work," said Tom Lewis, U.S. operating company president and sustainability executive champion at Louis Berger.

Louis Berger's global commitment to train its employees in the use of the Envision sustainable infrastructure rating system is a testament to the company's commitment to sustainability. The company recognizes that Envision helps project teams plan, design, construct and operate more resilient and sustainable infrastructure. This leads to stronger communities that are better equipped to deal with the effects of climate change and other variables that can impact infrastructure over the long run.

ISI's Envision sustainable infrastructure rating system provides a framework to assess and rate the social, environmental and economic benefits of all types and sizes of infrastructure projects. As a charter member of ISI, Louis Berger is now one of a select group of companies that has at least 100 ENV SPs.

"Companies with credentialed ENV SPs are well equipped to evaluate the levels of infrastructure sustainability," said John Stanton, ISI President and CEO. "ENV SPs can help their clients determine not only the right project to pursue, but also how to plan, design, construct and operate the project in the most sustainable way, which includes economic, social and environmental considerations."

Louis Berger is implementing Envision across priority regional markets in the U.S. and Panama. Additionally, the company is applying the Envision assessment process within business units where the rating system can have an immediate impact, including Louis Berger's planning, environment, economics and disaster management services across the transportation and power and energy markets.
