Infrastructure and transportation are having a moment in media coverage and political efforts. These umbrella terms mostly bring ports, bridges, and roads to mind, but they also include something in Air Sciences’ wheelhouse: MOVES, the MOtor Vehicle Emission Simulator, developed and funded by the United States Environmental Protection Agency (EPA). Now in its third iteration, MOVES provides a snapshot of tailpipe emissions for on- and off-road motor vehicles. The model encompasses six common air pollutants (ground-level ozone, particulate matter, carbon monoxide, lead, sulfur dioxide, and carbon dioxide, known collectively as criteria air pollutants), greenhouse gases, and hazardous air pollutants.
The Oregon Department of Environmental Quality (DEQ) has issued the final Oregon Nonroad Diesel Equipment Survey and Emissions Inventory, completed with the help of Eastern Research Group, Inc. (ERG); Good Company LLC; and Oak Leaf Environmental, Inc. The aim of this study was to generate Oregon-specific data of non-road equipment characteristics, such as: engine age, activity rate, fuel consumption, and geographic distribution.
