Director, Supply Chain


Areas of expertise: Corporate partnerships, fleet vehicles, green supply chain

Jason Mathers, director of supply chain, leads mobile source emission reduction efforts for the Corporate Partnership Program of Environmental Defense Fund. He is currently focused on increasing the carbon efficiency of goods movement and cutting emission from corporate vehicles.

Jason recently launched a new effort to reduce emissions from freight movement – the source of 6% of human-generated global warming pollution. As part of this work, Jason is cataloging current best practices and developing a framework for managing emissions from supply chain logistics. Through this work, Jason is collaborating broadly with leading companies, third-party logistics providers, academia, and professional associations. 

Jason has partnered with PHH Arval to develop the nation’s first greenhouse gas management program for fleets.  He broadly disseminated the best practices and tools needed to track and reduce fleet ghg emissions, including creating a fleet greenhouse gas calculator and developing a suite of training materials on fuel-smart driving behaviors. Building off the success of these efforts, Jason teamed-up with Donlen to issued a challenge to the fleet industry to cut emissions 20% over the next five years. 


Prior to joining Environmental Defense Fund in 2006, Jason managed the Sound Science Initiative of the Union of Concerned Scientists. He has an MA in economics from Suffolk University. He is a veteran of the U.S. Navy, serving onboard the USS Normandy (CG-60).
