The CLEERS Industry Priorities Survey supports one of the core CLEERS objectives: gathering feedback from industry on critical emissions control research needs. It was designed as a method for capturing a snapshot of the technology areas and development needs that are of highest importance to our industrial partners. The survey was initiated in 2007, and conducted in 2008, 2011, 2013 and 2015. The survey has been modified with each iteration to best capture recent directions in engine and aftertreatment development as identified by the CLEERS Coordinating and Advisory Committees. The results from the survey are used to guide the ongoing emissions control research programs at the DOE national laboratories, and to provide information to DOE program managers and DOE Advanced Engine Crosscut Team members to support their research planning. Survey reports are available below.
