These initiatives are supported by government strategies aimed at fostering a sustainable transportation ecosystem, signaling a commitment to both environmental stewardship and the promotion of energy efficiency.

Current Vehicle Landscape: Preferences and Powertrain Segments

The vehicle landscape in South Africa is currently dominated by Internal Combustion Engine (ICE) vehicles, which are favored for their reliability and the extensive fuel infrastructure supporting them. Popular models include the Toyota Hilux and Ford Ranger, reflecting the country's preference for durable and versatile vehicles capable of navigating diverse terrains. However, the landscape is gradually evolving, with Hybrid Electric Vehicles (HEVs) like the Toyota Corolla Cross gaining popularity due to their efficiency and lower emissions. The electric vehicle (EV) sector, though still in its infancy, is witnessing growth, with over 500 battery electric vehicles (BEVs) sold in 2022, marking a significant milestone. This shift towards electrification is indicative of changing consumer preferences and a growing awareness of the environmental impacts of transportation.

Electric Vehicle Market Overview and Trends

South Africa's EV market is showing signs of growth despite several challenges. In 2022, the market saw an increase in BEV sales, surpassing 500 units for the first time. This growth trend continued into the early months of 2023, suggesting potential for further expansion. However, EVs still represent a small fraction of total vehicle sales, highlighting the nascent stage of the market. The growth in HEV sales, reaching 4,050 units in 2022, underscores a broader acceptance of electrified transport options among South African consumers. High import duties and taxes on EVs pose significant barriers to widespread adoption, favoring premium models and limiting accessibility. Despite these hurdles, the increasing sales of BEVs and HEVs signal a slow but positive shift towards electrification in the South African automotive market.

Energy Context: Electricity Emission Factors and Implications for Electrification

South Africa's electricity sector, heavily reliant on coal, results in a high CO2e emission factor of 0.900 kg CO2e/kWh, placing it among the countries with the highest emissions intensity globally. This context presents a significant challenge for the environmental benefits of transitioning to EVs. The high carbon intensity of the grid means that, without substantial integration of renewable energy sources, the switch from ICE vehicles to BEVs may not yield the expected reductions in CO2 emissions. Addressing this challenge requires a multifaceted approach, including the adoption of renewable energy technologies and the development of a greener electricity grid to enhance the sustainability of electric mobility.

Challenges and Opportunities in EV Adoption

EV adoption in South Africa faces considerable challenges, primarily due to the country's high electricity emission factor and the lack of supportive infrastructure.

Additionally, the growing global focus on EV manufacturing and the potential for local production present avenues for economic development and job creation, aligning with broader environmental and sustainability goals.

Additional Insights: Shaping the Future of Transportation

As South Africa navigates the transition towards sustainable fleet management and vehicle electrification, the journey is marked by both challenges and opportunities. The country's high electricity emission factor and reliance on coal power necessitate innovative solutions to realize the environmental benefits of EVs. However, the increasing adoption of HEVs and the potential for further BEV growth underscore the changing dynamics of the South African vehicle market. The government's commitment to reducing emissions through policy measures and the development of a more sustainable transportation infrastructure are critical steps towards a greener future. As the global automotive industry continues to evolve, South Africa's efforts to embrace electric mobility will play a pivotal role in shaping the future of transportation within the country.

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

In South Africa, the corporate fleet is currently undergoing a significant transition to embrace a more sustainable and environmentally friendly future. The base fleet predominantly consists of ICE vehicles, with a total count of 99 units. In a forward-looking scenario, the reasonable recommended transition envisages a dramatic decrease of ICE vehicles to 12, promoting a shift towards HEVs which are expected to increase from 1 to 88. Notably, the transition plan does not incorporate PHEVs or BEVs, reflecting the practical constraints of the current South African context

This transition aligns with South Africa's status as a country with a high electricity emission factor of 0.9006 kg CO2e/kWh, where electricity is predominantly generated from fossil fuels, leading to high CO2 emissions per unit of electricity. Despite the challenging environment for EV adoption, characterized by less than 0.1% of vehicle sales being electric and infrastructural development being non-existent, the corporate fleet strategy prioritizes HEVs, acknowledging their lower emissions compared to BEVs without direct access to renewable electricity.

The recommended shift is not just a response to global sustainability trends but is also a strategic adaptation to the unique South African energy landscape. It underscores the need for innovative solutions like individual contracts for renewable electricity or the introduction of solar panels at company premises to make BEV integration more viable and environmentally beneficial.

The recommended transition of South Africa's corporate fleet from a base mix heavily reliant on ICE vehicles to a mix favoring HEVs is expected to yield substantial CO2 emission reductions. Currently, ICE vehicles contribute 439 tons of CO2e emissions. However, with the recommended transition, these emissions are set to decrease to 53 tons—a significant reduction reflecting the shift away from fossil fuels.

HEVs will see an increase in their CO2e emissions output from 3 to 293 tons, owing to their larger presence in the new fleet composition. However, the absence of PHEVs and BEVs in the recommended fleet mix case indicates a cautious approach towards electrification, given the country's high electricity emission factor and the minimal reduction in CO2e emissions that BEVs offer over ICE vehicles in the South African context.

Overall, the total CO2e emissions for the recommended fleet mix are estimated at 346 tons, a notable decrease from the base case total of 442 tons. This transition, while primarily focusing on HEVs, represents a pragmatic step towards reducing the corporate fleet's carbon footprint in a country where direct benefits of electrification are curtailed by the high carbon intensity of the power grid.

The analysis suggests that while the immediate transition to HEVs is a positive move, long-term emission reductions will hinge on the country's ability to integrate renewable energy sources, making the future inclusion of BEVs more impactful in terms of CO2e emission savings.

The comparative analysis of CO2e emissions across different fleet scenarios in South Africa provides a nuanced understanding of the potential impacts of fleet electrification strategies. The base fleet mix, with a heavy dependence on ICE vehicles, results in 442 tons of CO2e emissions. In contrast, the recommended transition that favors a significant HEV presence decreases overall emissions to 346 tons.

An all-ICE fleet scenario would produce the highest emissions at 444 tons, underscoring the environmental imperative to diversify the fleet. Transitioning to an all-HEV fleet would reduce emissions to 333 tons, reflecting the immediate benefits of hybrids in a high-emission electricity context. An all-PHEV fleet would result in 446 tons of CO2e emissions, considering both fuel and electricity-based emissions, and an all-BEV fleet, using the country’s current average emission factor, would lead to 449 tons of CO2e emissions—indicating that without renewable energy, BEVs do not offer a significant advantage over ICE vehicles in terms of emission reductions.

However, scenarios incorporating renewable electricity show more promise. An all-BEV fleet with 25% renewable electricity reduces CO2e emissions to 336 tons, 50% renewable electricity to 224 tons, and 75% renewable electricity to 112 tons. These reductions illustrate the critical role that renewable energy plays in enhancing the environmental benefits of BEVs.
