A Tesla Model S owner in Singapore was slapped with a fine for high CO2 emissions. Elon Musk, the co-founder and CEO of Tesla, has discussed the issue with Singapore’s prime minister.

Joe Nguyen paid about $51,000 for the Model S and got the electric car from Hong Kong to Singapore. Nguyen was expecting a rebate under Singapore’s Carbon Emissions Vehicle Scheme (CEVS). However, he got a shock when he was fined S$15,000, about $11,000, after his Model S underwent mandatory emissions testing by Singapore’s Land Transport Authority (LTA).

A spokesperson for the LTA explained that the Model S in question was tested under the United Nations Economic Commission for Europe (UNECE) R101 standards. The test result of the electric car suggests that the vehicle consumed 444 watt hours of energy per kilometer.

“As for all electric vehicles, a grid emission factor of 0.5 g CO2/Wh was also applied to the electric energy consumption. This is to account for CO2 emissions during the electricity generation process, even if there are no tail-pipe emissions. The equivalent CO2 emission of Mr. Nguyen’s car was 222 g/km, which is in the CEVS surcharge band,” says the LTA spokesperson.
