Just like we don't take the emissions of the oil refinery that produces the gasonline nor the emissions of the transportation system that delivers it to the fueling stations into account when determining whether a car meets LEV, ULEV, SULEV, etc. standards, we should similarly not do so when determining whether a particular vehicle is considered a ZEV.
Double standard? Yes, absolutley unquestionably. Justifiable? Only if you are a hypocrite with an agenda.
Very good point. I have to check, but I think there is an European standard considering emissions for plug-in hybrids driving in electric mode. If memory serves, they use the same driving cycle they use for 'regular' cars and measure the power consumption (in kWh per 100 km). The result will be multiplied with the so called 'EU Mix' CO2 value, the average of the CO2 emission for all different kinds of power generation, and you have a similar figure in CO2 per km. That being said, you're perfectly right that only electric cars use these well-to-wheel figures, so there is a double standard.
