Topic: Driving to the Tragedy of the Commons Using a Diesel Engine


Diesel engines are the most efficient combustion engine currently available. Their power, durability and economy make them the engine of choice for a wide variety of applications, most notably in freight movement. Their exhaust, long regarded as a nuisance for the smoke and odor, is increasingly implicated in elevated risk for cardiovascular, neurological and respiratory adverse health impacts, as well as being a notable contributor to other environmental impacts like regional haze and climate change. The state of Oregon, since 2001 has undertaken a voluntary, incentive supported approach to owners and operators of existing diesel engines to reduce emissions using a variety of strategies with mixed results. This discussion will summarize that effort, evaluate the economics of cleaning up diesel engines as a public health strategy and outline the potential for further mitigation.
