The "Base Fleet" percentage is set according to the sales ratio of each powertrain in Australia 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 Australia 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 Australia 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 Australia's fleet.

In Australia, transitioning from a current fleet composition to a more sustainable and electrified vehicle mix involves significant changes in the number of cars across different powertrains. Currently, the fleet predominantly consists of ICE vehicles, totaling 97 units. This is reflective of traditional corporate fleet compositions, heavily reliant on fossil fuel-powered vehicles. In a move towards sustainability, the recommended transition sees a drastic reduction in ICE vehicles to 34 units, signifying a commitment to reducing carbon footprints and environmental impact.

The transition strategy also introduces HEVs as a significant component of the fleet, with their numbers increasing from zero to 63 units. This shift acknowledges the current infrastructural limitations in Australia, where high electricity emission factors make HEVs a more viable option for reducing emissions than BEVs. Despite Australia's rank as one of the Very High Emission Countries due to its reliance on fossil fuel-generated electricity, this strategy optimizes the available technology to mitigate environmental impact.

The presence of BEVs in the fleet remains constant at 3 units, underscoring the challenges posed by Australia's energy grid and the need for infrastructural improvements to fully leverage the potential of BEVs. This cautious approach to BEV integration reflects the current readiness of the country's EV infrastructure and the strategic emphasis on HEVs as a transitional technology towards lower emissions.

The CO2 emission implications of transitioning corporate fleets in Australia from their current state to a more environmentally friendly composition are substantial. Initially, the fleet's total CO2 emissions, dominated by ICE vehicles, stood at 407 tons from fuel combustion. Electrification in the form of BEVs contributed an additional 11 tons of CO2, calculated based on the country's high electricity emission factor, summing up to 418 tons of CO2 emissions for the base fleet mix case.

The proposed transition reduces ICE vehicles, leading to a significant drop in fuel-based CO2 emissions to 143 tons. Introduction of HEVs, which do not directly emit CO2 from electricity, adds a new dimension to the fleet, contributing 198 tons to the CO2 footprint, based purely on their more efficient fuel use. BEVs maintain their 11 tons contribution, reflecting the constant number of electric vehicles in the transition plan. This results in a total of 352 tons of CO2 emissions for the recommended fleet mix, marking a notable improvement in reducing the fleet's environmental impact.

This transition not only addresses immediate CO2 emission reductions but also sets a foundation for further improvements. As Australia's electricity grid becomes greener, the CO2 emissions attributed to the BEV segment of the fleet will decrease, amplifying the benefits of this transition.

The comparison of various fleet mix cases in terms of CO2e emissions underlines the impact of different electrification strategies in Australia, considering its status as a high-emission country for electricity generation. The base fleet mix case, heavily reliant on ICE vehicles, results in 418 tons of CO2e emissions, setting a high baseline for improvement.
Transitioning to a recommended fleet mix reduces total emissions to 352 tons of CO2e, showcasing the effectiveness of incorporating HEVs and maintaining a conservative number of BEVs under current electricity generation conditions. This transition acknowledges Australia's electricity emission factor and leverages HEVs' efficiency to achieve reductions.

Exploring alternative scenarios, an all-ICE fleet would result in 420 tons of CO2e emissions, marginally higher than the base case. An all-HEV fleet emerges as a significantly better option, reducing emissions to 315 tons, underscoring the potential of hybrid technology in current conditions. The all-PHEV fleet case illustrates a balance between fuel and electricity-based emissions, totaling 389 tons of CO2e, reflecting the intermediate position of PHEVs in the emission spectrum.

The most ambitious scenarios involve transitioning to an all-BEV fleet, with varying degrees of renewable electricity incorporation. These cases highlight the critical role of clean energy in realizing the full potential of BEVs, with emissions ranging from 358 tons (country average emission factor) down to 90 tons (75% renewable electricity), demonstrating a direct correlation between renewable energy use and CO2e emission reductions. This analysis underscores the importance of energy infrastructure in determining the environmental impact of fleet electrification strategies in Australia.
