Does the supposedly clean, green Tesla Model S really pollute more than a gas-guzzling Jeep Grand Cherokee sport-utility vehicle? In an exhaustive 6,500-word article on the financial website Seeking Alpha, analyst Nathan Weiss lays out a case that the Model S actually has higher effective emissions than most.'

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. —Nie et al.
A fleet average nonfuel nonexhaust VOC emission factor of 58 ± 39 mg veh –1 km –1 was calculated for the missing source, which is greater than the total of all VOCs emitted from vehicle exhausts and their associated evaporative fuel losses. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,
