Testimony of the Diesel Technology Forum Before the U.S. Environmental Protection Agency, April 12, 2022

WASHINGTON (April 12, 2022) – The DTF has prepared the following testimony for delivery on April 12, 2022.


Testimony of the
Diesel Technology Forum 
Before the
U.S. Environmental Protection Agency
Docket Numbers: EPA-HQ-OAR-2019-0055; FRL-7165-03-OAR


Thank you for the opportunity to appear today. The Diesel Technology Forum is a not-for profit educational group that represents diesel engine vehicle and equipment manufacturers, suppliers of engine components and emissions control systems, as well as producers of renewable and petroleum fuels. DTF member companies will or have already provided substantial comments on various aspects of the rule, and we would like to emphasize the following.

By building off of today’s success, we can better address tomorrow’s needs as well as the longer-term opportunities. 


Today’s Diesel Technology Is a Success Story


Future Emissions Standards Must Encourage Continued Investment Through Proper Balance in Timing, Stringency And Other Factors


Reducing Emissions should be more than just Setting New Engine Standards, but also Implementing More Immediate Term Solutions Like Use Of Renewable Fuels And Accelerating The Turnover Of The Legacy Fleet


Future And Zero Emission Vehicles



Above all else, this proposed rule must enable continued investment in the next generation of diesel technology by manufacturers, suppliers, and their customers. Without that, none of the anticipated benefits will accrue, older trucks will stay on the road for longer, and both manufacturers and suppliers will not have the capital to invest in future fuels and technologies.

In the meantime, getting more of the current generation of advanced diesel technology on the road and using more advanced low carbon renewable biodiesel fuels will continue to deliver everything we need; air quality improvements and sustaining progress on climate change. That’s something everyone should be able to get behind.

We look forward to continuing dialogue with the agency, and all stakeholders, about this rulemaking as well as the future for commercial vehicles powered by advanced diesel engines.

Thank you for the opportunity to submit this testimony.


Delivered by Allen Schaeffer, Executive Director, Diesel Technology Forum
