Lumped Parameter Model (LPM) for Light-Duty Vehicles
EPA’s Lumped Parameter Model (LPM) is a free, desktop computer application that estimates the effectiveness (CO2 Reduction) of various technology combinations or “packages,” in a manner that accounts for synergies between technologies.
EPA used LPM V2.12 to support the 2017-2025 Final Light-Duty Vehicle Greenhouse Gas Rulemaking.
LPM V2.12 is available for download below.
