World Environment Day, observed every year on 5 June, exists to encourage action that protects and restores the planet. But the conversation cannot remain focused only on the scale of the environmental challenge. It must also focus on the systems being built to replace the old ones.
With 2030 looming as a critical deadline for global emissions reductions, the urgency is real. South Africa is the highest greenhouse gas emitter in Africa and ranks among the top 15 largest emitters globally, largely because of its heavy reliance on coal-fired electricity generation. The country is already at risk of not meeting its 2030 carbon reduction targets, a failure that would put the longer-term goal of net-zero emissions by 2050 further out of reach.
Transport compounds the problem directly. In 2024, the Department of Forestry, Fisheries and Environment’s identified the local transport sector as a major greenhouse gas contributor, accounting for 12% of the country’s carbon emissions. The draft sectoral emissions target report set a target of reducing CO2 emissions in the sector by 4.5 million tonnes by 2030 and identified increased electric vehicle uptake as one of the primary pathways to achieving it.
But the conversation around electric vehicles in South Africa cannot end with the vehicle itself. An EV is only as clean as the energy used to charge it. Electric vehicles represent a major improvement over internal combustion engines. They produce zero tailpipe emissions and reduce urban air pollution. Yet there is an uncomfortable contradiction in South Africa’s transition story, charging an electric vehicle from a coal-heavy electricity grid still carries an indirect carbon footprint. Electrification alone is not enough. Any strategy to increase the number of EVs on our roads must also include a plan to develop the sustainable, green infrastructure needed to power them.
In South Africa, that infrastructure is beginning to take physical form. This month, CHARGE launched two more off-grid, solar-powered EV charging stations along the N3 corridor, one of the country’s most important freight and transport routes linking Johannesburg and Durban – CHARGE N3 Roadside at the Reitz Interchange in the Free State, and CHARGE N3 Tugela at the Colenso-Winterton Interchange in KwaZulu-Natal. Both stations operate entirely off-grid using solar-powered microgrids and battery storage, with no dependence on Eskom and no reliance on imported fuel.
In the first two days of operation across both sites, more than 30 electric vehicles, including passenger cars and commercial trucks, were charged using approximately 1 MWh of energy generated entirely from solar and battery storage. Not a single litre of diesel was burned. Not a single unit of electricity was drawn from the national grid. That is what a genuinely low-carbon transport system begins to look like.
According to Naamsa, South Africa’s new energy vehicle (NEV) parc stood at 79,340 vehicles as of March 2026. The annual electricity demand is approximately 397 GWh, or around 1.1 GWh per day. comparable to the annual electricity consumption of a town the size of Stellenbosch in 2021. This illustrates the importance of building renewable energy infrastructure alongside vehicle adoption.
The concept of an electric highway extends far beyond passenger vehicles. South Africa’s freight sector is increasingly road-based, driven in part by the long-term shift of cargo from rail to road. According to the Department of Transport’s “Green Transport Strategy for South Africa (2018–2050)”, heavy goods vehicles account for approximately 34% of traffic on the N3 corridor, the country’s busiest freight route. As battery technology improves and operating costs decline, the electrification of freight is becoming commercially viable. Medium-duty trucks, particularly those below 14 tonnes and up to non-rigid 20-tonne payloads, can already be deployed effectively in South African operating conditions. The vehicles are available today. The critical requirement now is the charging infrastructure that will enable them to operate at scale.
CHARGE’s expansion has been supported by a R100 million investment from the Development Bank of Southern Africa, reflecting growing institutional confidence in renewable transport infrastructure as a credible path to decarbonising the sector.
Investment in green charging infrastructure by the private sector, operating within a supportive policy environment, will reduce emissions while and creating the jobs and growth that accompany any major infrastructure build-out. The infrastructure being developed across the country demonstrates that the transition does not need to wait for perfect conditions. It can begin corridor by corridor, site by site, using technologies already available today.
Following the N3, CHARGE will advance to the N1 corridor, then to 60 more sites and ultimately a 120-station national network covering South Africa’s major transport routes.
The path to zero emissions will not be shaped by electric vehicles alone. It will be shaped by the renewable energy infrastructure that makes those vehicles viable at scale. South Africa has the solar resource and the technology. The only question is whether we move quickly enough to meet the 2030 targets that will define the decade.
A carbon-neutral national highway is no longer a thought experiment. It is becoming a route you can drive.
