This .zip archive contains the EPA OMEGA analysis files relating to the "Final Rulemaking to Establish 2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and CAFE Standards."  Details about this rulemaking can be found on the EPA website at http://epa.gov/otaq/climate/regs-light-duty.htm.  

This archive contains the OMEGA inputs, OMEGA outputs, and benefits post=processor used in this final rulemaking.  

In order to reduce complexity and file size, there are several additional pre- and post-processors which are not being posted in this zip archive.  These additional post-processors are also publically available, and are in docket "EPA-HQ-OAR-2010-0799."  These post-processors (ranking algorithm, TEB/CEB calculator, technology penetration calculator, stranded capital calculator, summary processor, etc.)  reformat and interpret OMEGA output files to produce the information that is directly used in the rulemaking.  

This archive is organized by market forecast.  At the top folder level, the benefits post processor contains the estimated impacts of all modeled scenarios for both MY 2008 and MY 2010 forecasts.  Sub-folders exist for the MY 2008 and MY 2010 based market forecasts.  Each market forecast folder contains reference and control case runs in MY 2016, MY 2021 and MY 2025.  Within the MY 2008 market forecast, the inputs and outputs for all of the sensitivity cases are also available.
