The "Base Fleet" percentage is set according to the sales ratio of each powertrain in Singapore for the year 2023. (For countries where sales ratios cannot be obtained, it is assumed all are ICE vehicles.) The "Recommended Fleet" is designed to be realistic (based on a rank determined by the Electricity Emission Factor Category and EV Readiness Category, deciding a practical range) and efficient in reducing CO2e emissions. It is not expected that the entire fleet will switch to this mix at once but rather after one or two renewal cycles over about 4 to 8 years, considering the usual fleet renewal period is around 4 years. This is viewed as a recommendation for the fleet composition in 4 to 8 years.

The calculation of CO2e emissions is based on a fleet of 100 vehicles traveling an average of 30,000 km per year. Therefore, if your company's fleet size in Singapore is 1,000 vehicles, multiplying the results by 10 will give you an approximate value. For fuel, it is assumed all vehicles use petrol (2345.02 CO2e g/L), and for electricity, the average emission factor of Singapore is used. For PHEVs, it is calculated assuming 50% electricity usage and 50% fuel usage.

Analysis of Fleet Transition from Current State to Sustainable Future

This refers to the average CO2e emissions per kilometer calculated based on the actual energy (Fuel and Electricity) used. It also takes into account the size of the vehicles used in Singapore's fleet.
