​​​​​​​​​​​​​​​​NEW YORK (October 26, 2021) Clarion Partners LLC, a leading real estate investment manager, announced today that Karen Mahrous has joined the Firm as a Senior Vice President and Head of ESG. Karen is based in Clarion’s New York City office and reports to Jeb Belford in his new capacity as CIO.​

In this critical new position for the Firm, Karen will work with cross-functional teams throughout the organization to develop a formal framework to implement the Firm’s recently announced commitment to the Urban Land Institute’s Net Zero by 2050 Greenprint program and strengthen Clarion’s alignment with the United Nations Sustainable Development Goals (SDG’s).

​In addition, she will work with the Asset Management team to pursue carbon reduction programs across all sectors in our global portfolio, and be responsible for supporting Clarion’s industrial team in implementing its new prototype for the U.S. Green Building Council’s LEED certification program for new industrial development. Importantly, Karen will partner with Human Resources to manage our growing number of diversity, equity, and inclusion initiatives, including supporting the PREA SEO and Christo Rey minority internship programs and  identifying  opportunities  to further  support historically disadvantaged communities.

“We are thrilled to welcome Karen to the Clarion team at this pivotal time as we seek to expand our rigor around already important work within the ESG space,” said Clarion Partners Chief Executive Officer Dave Gilbert. “Karen brings industry expertise, deep experience, thought leadership and practical skills to this critical function.”

​Karen joins Clarion from CodeGreen Solutions, an energy and sustainability consultancy firm specializing in the real estate industry. While with CodeGreen, Karen developed and led a corporate sustainability team that provided ESG strategic advisory and reporting services to a variety of real estate companies. Karen brings experience in managing sustainability program implementation, including the certification of over six million square feet under the LEED and WELL programs nationwide. She holds an M.S. in Sustainability Management from Columbia University, is a LEED and WELL AP, and sits on the GRESB North America Benchmark Committee.

“Clarion has a tremendous platform as an established industry leader,” said Mahrous. “I look forward to enhancing the existing ESG program and leading the path forward toward Net Zero and the Firm’s other crucial ESG initiatives.”
