Tesla Model S
The Model S was charged S$15,000 (U.S. $10,481) for exceeding the carbon emissions requirement. All the while, the owner, and anyone else that knows of the model, likely would have expected a rebate.
Revised CEVS in affect through June 30, 2017
CEVS revised breakdown beginning July 1, 2015:
Under Singapore’s revised Carbon Emissions-Based Vehicle Scheme (CEVS), all new cars and imported used cars registered from 1 July 2015 with low carbon emissions of less than or equal to 135g CO2/km qualify for rebates of between S$5,000 (US$3,614) and S$30,000 (US$21,681), which are offset against the vehicle’s Additional Registration Fee (ARF). Cars with high carbon emissions equal to or more than 186g CO2/km incur a registration surcharge of between S$5,000 and S$30,000.
When Singapore’s Land Transport Authority (LTA) tested the vehicle it was shown to consume 444 Wh/km of electric energy. This number is nearly double U.S. EPA's estimates. The emissions produced from that use of energy, estimated through the CEVS equation, reached 222g CO2/km.
The Tesla was the first electric car not qualifying for the rebate in Singapore, according to the LTA.
U.S. examples show the same Tesla Model S P90D with emissions falling between (155g CO2/km) and (167g CO2/km). While these numbers show that the car would not receive any rebate, the Tesla should not have received a surcharge either.
Tesla released the following statement to InsideEVs on their interpretation/understanding of the emissions of the Model S:
The Model S that our customer imported into Singapore left our factory in 2014 with energy consumption rated at 181 Wh/km. As the Land Transport Authority has confirmed, this qualifies as the cleanest possible category of car in Singapore and entitles the owner to an incentive rather than a fine.
Model S achieves this result because CO2 emissions in gas-powered cars are far higher than in electric cars. In Singapore, electricity generation releases roughly 0.5kgCO2/kWh. Based on energy consumption in Model S of 181 Wh/km, this results in 90 g CO2/km. Driving an equivalent gas-powered car like the Mercedes S-Class S 500 results in emissions of approximately 200 gCO2/km. And because of oil extraction, distribution, and refining, approximately 25% more has to be added on top of that to calculate the real carbon footprint of gas-powered cars. That means an electric car like the Model S has almost three times lower CO2 per km than an equivalent gas-powered car. Moreover, as Singapore increases the percentage of grid power from solar and wind, the CO2 from electricity drops with each passing year.
We are having cooperative discussions with the LTA to ensure a proper understanding of these issues and to make sure that they are correctly testing our customer’s Model S. Based on the positive nature of those discussions, we are confident that this situation will be resolved soon.
