Country Case Study
The "Base Fleet" percentage is set according to the sales ratio of each powertrain in Japan 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 Japan 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 Japan is used. For PHEVs, it is calculated assuming 50% electricity usage and 50% fuel usage.

The introduction of PHEVs and BEVs into the fleet, although in smaller numbers, represents a strategic move towards leveraging Japan's existing infrastructure and moderate emission factor. PHEVs will contribute 15 tons of CO2e emissions, a slight increase from the base mix due to their higher numbers, while BEVs will see an increase from 2 to 22 tons of CO2e emissions, owing to their greater prevalence in the recommended fleet.
Overall, the recommended transition is expected to generate a total of 290 tons of CO2e emissions, marking a substantial reduction from the 363 tons in the base mix. This decrease underscores the potential impact of integrating alternative powertrains into corporate fleets. As Japan's infrastructure for electric vehicles improves, and the market for BEVs expands, further CO2 emission reductions can be anticipated, affirming the strategic direction towards electrification.
Comparative Analysis of CO2e Emissions Across Fleet Scenarios
CO2e From Fuel (Scope 1)
CO2e From Electricity (Scope 2)
Comparing CO2e emissions across different fleet scenarios for Japan reveals the potential impacts of various electrification strategies. The base fleet mix, predominantly ICE vehicles, incurs 363 tons of CO2e emissions. Transitioning to the recommended mix, which includes a significant number of HEVs and an increased presence of BEVs, CO2e emissions are reduced to 290 tons.
An all-ICE fleet would result in the highest emissions at 387 tons, emphasizing the need for diversification of powertrains. An all-HEV fleet, although not entirely emission-free, would decrease emissions to 290 tons, while an all-PHEV fleet would produce 295 tons of CO2e emissions, suggesting a balance between fuel and electricity-based emissions.
The most substantial reductions are observed in scenarios with a full transition to BEVs, especially when considering the integration of renewable electricity. An all-BEV fleet with the country's current average emission factor would lead to 202 tons of CO2e emissions. However, as the share of renewable electricity increases, CO2e emissions could potentially decrease to 152, 101, and as low as 51 tons for fleets powered by 25%, 50%, and 75% renewable electricity, respectively.
These findings highlight the transformative potential of renewable energy in reducing emissions from corporate fleets. Japan's scenario analysis serves as a crucial guide for strategic fleet management decisions, showcasing how varying levels of electrification and renewable energy integration can dramatically alter the environmental impact of corporate transportation.
