On the record
Represented by:

Allen Schaeffer is Executive Director of the Diesel Technology Forum, a not-for profit educational organization of global leaders in advanced diesel engine, equipment, and fuels technology. The Forum’s work focuses on the sustainability of advanced diesel technology in a wide range of applications including commercial vehicle, power generation, marine, rail, construction, and other industrial applications. Schaeffer has helped lead the group since its founding in 2000. He is the forum’s primary spokesperson, and has appeared in reports by The Associated Press, The New York Times, and Automotive News, among others.

He has more than 30 years of experience working with environmental and public health issues, as well as transportation, climate, and energy policy.

In his own words:
“Climate change, economic and social equity are complex and multidimensional challenges of our time. They won’t have a one size fits all solution. We have to work together on the ways and means to solve these problems, and to make this world a better place for all generations.”

Current Areas of Focus:
EPA regulatory activities regarding clean air, climate, emissions, health effects, mobile sources, renewable biofuels, transitions to a clean energy future, decarbonization of transportation and other industrial sources

Background & Education:
• Vice President of Environmental Policy at the American Trucking Associations (ATA), where he represented the trucking industry in legislative and regulatory policy matters at the national level and was principal environmental and energy advisor to a research foundation and 60 affiliates at the state and regional levels.
• Appointed to EPA’s Federal Advisory Committee Subcommittee on Ozone, Particulate Matter and Regional Haze and the Clean Diesel Workgroup of the Mobile Source Technical Review Committee.
• A Maryland native, Schaeffer holds a Bachelor of Science degree in Zoology from the University of Maryland College Park and a Master of Environmental Health Sciences degree from Johns Hopkins University Bloomberg School of Public Health in Baltimore.
