UPS names Tamara Barker new Chief Sustainability Officer

UPS (NYSE: UPS) announced today that Tamara Barker has been named the company’s new Chief Sustainability Officer (CSO) and Vice President of Environmental Affairs, effective immediately. Barker will succeed Rhonda Clark, a 26-year UPS veteran, who has been named Vice President of Corporate Plant Engineering for UPS.

Barker, a nearly 30-year UPS veteran, has held a wide array of roles at the company, most recently as the west region director of plant engineering.

“As our business continues to grow, UPS is committed to meeting increased demand in ways that consume less energy and produce fewer emissions, yet maintain high service levels for customers,” said Mark Wallace, UPS senior vice president global engineering and sustainability. “Rhonda helped push UPS closer to our sustainability goals and her new assignment will contribute to the company’s ability to expand facility projects to meet our growing marketplace demands. Tamara’s plant engineering leadership, combined with her many years of distinguished UPS service, places her in a strong position to make continued progress on our environmental sustainability commitments.”

As CSO and Vice President of Environmental Affairs, Barker will work to advance UPS’s 2020 sustainability goals and initiatives; drive environmental affairs and plant engineering activities internationally; and lead cross-functional committees responsible for global sustainability reporting, global greenhouse gas (GHG) emissions reduction strategy, and employee engagement in sustainability.

As Vice President of Corporate Plant Engineering, Clark will concentrate on the construction and expansion of automated facilities and innovative material handling systems, facility maintenance, and environmental and regulated goods compliance for UPS worldwide.
