Driver influence in hybrid vehicle economic appraisal
AbstractHybrids are seen as a potential solution to urban traffic pollution and energy consumption; however studies show how pollution economic appraisal is one order of magnitude lower than fuel cost putting all the burden of the economic success the hybrid capability of reducing fuel consumption.
Two Honda Civic Hybrid of the Italian Ministry of Environment fleet were constantly monitored while driven one each by the calmest and by the most aggressive of the Ministry drivers to assess driver effects on air pollutant emissions.
Measurements have shown how the aggressive driver emits 10 times more VOC, and 4 times more CO and NOx than the calm driver while consuming 35% more fuel. In the economic appraisal over the expected 14 years vehicle life however the aggressive driver costs 16 300 € while the aggressive one 22 500 € only 38% more. This is due to the extremely low cost of emissions (excluding CO2) which is 160 € for the calm driver and 610 € for the aggressive one for the entire life of the vehicle.
Unless pollutants are monetized according to the position where they are “left” in the atmosphere there is no way emission differences between cars and drivers can be reflected in any economic appraisal.
