Emerging Technology List
The following table lists information showing the potential capabilities of emissions reduction for emerging technologies. The table shows the projected percent reduction that EPA will recognize for emission reductions for each technology based on the information and data provided by the manufacturer. The percent reduction is subject to change after completing testing for verification. Actual emissions reductions will be a function of the individual applications.
The Emerging Technology list is intended to provide guidance in selecting a technology for the Clean Diesel Emerging Technologies Program’s Request for Proposals. A technology may reside on the Emerging Technology List for one year from the effective date. During that year, the manufacturer will seek full verification. The verification process officially evaluates the emission performance of the technology. Once verified, EPA will list the official performance data and associated information on the National Clean Diesel Campaign’s Verified Technology List. Please refer to the selection criteria below for more details.
Eligible entities interested in applying for funds under the Clean Diesel Emerging Technologies Program should consult with the manufacturer of the emerging technology about preparing the grant application (Retrofit Technologies Contacts).

Selection Criteria
The following outlines the selection criteria used for technologies included on EPA’s National Clean Diesel Campaign’s Emerging Technologies List:
- A technology may reside on the Emerging Technology List for one year.
- If a technology is fully verified within the first year, the technology will be added to the EPA Verified Technology List.
- If, after the first year, the technology has not been verified, EPA will review the status of the technology and determine whether the technology is eligible to remain on the Emerging Technology List.
- Once a technology is selected for use in an Emerging Technology project, that technology may be used for the entire project period, even if the technology has been fully verified by EPA.
- Should EPA determine an Emerging Technology was misrepresented in the application, performance was not fully described, or concerns for safety and/or public health exist, EPA may remove a technology from the Emerging Technology List, revise operating criteria, or impose other restrictions for use in Emerging Technology grant programs.
- Should a technology be removed from the Emerging Technology List without receiving verification status, that technology is no longer eligible for use on any Clean Diesel grant program.
