CARB survey letter

An inventory is a count of units not usage, Ramcharger360's post was the first post to reference usage. In the multiple threads that have been done none have mentioned usage, that post was the first.

CARB's emissions inventory is much more than just a unit count. It models emissions from populations of various vehicle types by vehicle model year for a given calendar year, fuel type, season, county, etc. Usage is one of the parameters used by the model to calculate emissions for a particular source category.
