3.4.4 - December 6, 2022 New Features The EV Minimum and Hydrogen Vehicle Minimum policies have been replaced with a single Zero-Emissions Vehicle (ZEV) standard policy. Which vehicle technologies qualify as ZEVs can be customized in trans/BVTQaZ and trans/VTQaZ for a policy scenario that differs. The EPS selects between qualifying vehicle technologies via economic factors. The new ZEV standard policy only applies to road vehicles, not aicraft, rail, or ships. BAU ZEV standards may be specified separately for up to 60 subregions (such as U.S. states within the national-scale U.S. model), and the EPS will increase ZEV sales to meet BAU ZEV standards or user-specified ZEV standards only in subregions where the standard is not already being met. This improves accuracy relative to using national, sales-weighted averages. Data Updates Updated trans/TTLE to use values directly from PNNL's GCAM model. The main difference is to increase the EPS sensitivity to costs for new passenger LDVs. Updated the social cost of carbon to use the latest estimtes from the EPA, released in November 2022.
