- The emission factors adopted in this calculator have considered the emissions from CO2, N2O and the CH4. The results are presented in units of kilogram of the carbon dioxide equivalent. (CO2-e/kg)
- The calculation is based on the general performance (km/kWh) of typical EV vehicles
- 365 days of traveling day per year is assumed for total traveling distance calculation
Benefits of EVs / Why EVs
EVs offer a number of great benefits over conventional cars without reducing your joy of driving.
Reduce CO2 Emission
CO2 generation due to EV charging is only 1/3 of petrol vehicle. (According to average figures of factory specifications of selected 16 EV vehicles of 10 brands, and with reference emission and consumption figures from The Environmental Protection Department of HK (HKEPD).)
EV gives a more comfortable driving experience, as there is no sound and no vibration from the car engine.
Save Every Ride
The operation of EV is generally the same as ordinary vehicles. However, the cost of every ride and the regular maintenance fee are much lower.
Good to Health
EV does not emit any exhaust fumes mean better air quality, less health problems and costs caused by air pollution.
Drive with Support
With CEM mobile APP, you can easily start charging, find chargers, access records and report problems.
Save Maintenance Cost
With the absence of exhaust systems, starter motors, fuel injection systems and radiators, vehicle maintenance cost will be less.
