  "field": "Environment",
  "definition": "1. Unique combination of basic engine, engine code, inertia weight class, transmission configuration, and axle ratio within a base level.\n\n2. Unique combination of vehicle hardware and calibration (related to measured or modeled emissions) within a vehicle family. Vehicles with hardware or software differences, but that have no hardware or software differences related to measured or modeled emissions may be included in the same vehicle configuration. Note that vehicles with hardware or software differences related to measured or modeled emissions are considered to be different configurations even if they have the same GEM inputs and FEL. Vehicles within a vehicle configuration differ only with respect to normal production variability or factors unrelated to measured or modeled emissions.\n\n3. Unique combination of basic engine, engine code, inertia weight class, transmission configuration, and axle ratio.",
