EPA Optimization Model for reducing Emissions of Greenhouse Gases from Automobiles (OMEGA). Core Model Version 1.4.1 Documentation.

摘要

On-road vehicles are the predominant source of greenhouse gas (GHG) emissions from the transportation sector. Of all on-road vehicles, light-duty vehicles and light-duty trucks (hereafter referred to as cars and trucks) produce the majority of the GHG emissions. There are many methods for reducing GHG emissions from cars and trucks due to the myriad technology options available to improve the efficiency of vehicles. A detailed analysis of the costs and benefits of various GHG emissions reduction requires an application that accounts for all the potential technologies. Therefore, EPAs Office of Transportation and Air Quality (OTAQ) has developed the Optimization Model for reducing Emissions of Greenhouse gases from Automobiles (hereafter referred to as the OMEGA model) to help facilitate the analysis of the costs and benefits of reducing GHG emissions from cars and trucks. This documentation accompanies the fifth public release of the OMEGA model. Versions 1.0.0 and 1.0.2 were respectively released with the noticed of proposed rulemaking and final rule regarding Model Year 2012-2016 Light-Duty Vehicle Greenhouse Gas Emissions Standards and Corporate Average Fuel Economy Standards. Versions 1.3.0, 1.4.0, and this version were respectively released with the first notice of intent, the proposed rulemaking, and the final rule regarding the 2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and CAFE Standards.
