Diesel Advocacy Group Testifies To EPA Ahead Of Emissions Reduction Proposal
Diesel Forecast To Be Commercial Fuel of Choice for “Foreseeable Future”
In the wake of president Barack Obama’s sweeping climate change proposal, the Environmental Protection Agency (EPA) convened a rulemaking hearing in Chicago to discuss the ramifications and implementation of the proposal and its potential effects on the commercial transport industry. Representing the interests of diesel engine manufacturers was Allen Schaeffer, executive director of the Diesel Technology Forum.
Schaeffer emphasized the predominance of diesel in today’s commercial transportation sector, representing more than 95 percent of commercial trucks. Thanks to significant improvements in emissions reductions, namely particulates and NOx, Schaeffer said he expected diesel to remain the predominant powertrain in the commercial vehicle sector for “the foreseeable future.” Thanks to more sophisticated engine management software and exhaust aftertreatment technologies, Schaeffer said clean diesel trucks put on the road between 2010 and 2014 have reduced carbon emissions by the equivalent of 2.4 coal-fired power plants and NOx emissions reductions equivalent to 158 coal power plants. Schaeffer advocated that any future regulations remain “fuel neutral” in regard to meeting emissions reduction targets.
As older trucks are taken off the road and replaced with newer models, emissions reductions are expected to improve even more. Currently, 38 percent of heavy-duty vehicles on the road are 2007 or newer and 20 percent meet 2010 emissions standards, which mandated strict limits on particulate matter (PM) and NOx.
