I read this on Wikipedia:

The vehicles constructed to meet the PZEV requirements also fall within the Super Ultra Low Emission Vehicles (SULEV)-category. Various techniques are used to reduce pollution in these vehicles. In order to qualify as a PZEV, a vehicle must meet the SULEV standard and, in addition, have zero evaporative emissions from its fuel system plus an extended (15-year/150,000-mile) warranty on its emission-control components, which incidentally covers the propulsion electrical components of a hybrid electric vehicle.

Where did you get the .07% per day? I tried to find something about .07% but didn't have any luck. Is this such a small percentage that it's consisdered zero? I realize that Wikipedia isn't always correct and maybe they didn't explain it fully.
