Johannesburg Edges Closer to Carbon Neutrality: What Local Leaders and Experts Are Saying

Johannesburg has reduced its per-capita carbon emissions for the third year running, with city officials and sustainability experts claiming that the City of Gold is now closing in on global leaders such as London and Singapore.

After years of lagging behind the world’s top urban centres, Johannesburg’s cleaner energy progress has arrived at a critical moment. Both municipal and provincial coalition leaders believe the city is now poised to leverage its ongoing infrastructure overhaul—crucial in a year that has seen Gauteng’s ANC-DA government working to solidify upgrades to roads, transport, and electrical grids across major nodes like Sandton and Rosebank.

On the Ground: Sandton to Soweto

Pockets of progress are most visible across high-density business corridors and historic districts. The Sandton Central Management District has funded retrofitting of office blocks along Rivonia Road with rooftop solar arrays and rainwater harvesting systems. Meanwhile, the Orlando East Eco-Hub—supported by the Department of Energy and local community groups—has become a showcase for low-cost, solar-powered housing models in Soweto. Representatives from Johannesburg City Power say partnerships with programmes like Rea Vaya’s electric bus initiative and the Alexandra Green Economy Trust are paying off, pushing down peak-hour emissions in several targeted zones.

Lebogang Nkosi, a senior official in the Mayor’s Office, confirms the city is “on track” to meet the 2027 target of cutting municipal energy emissions by 35% compared to 2019 levels. "We're investing more than R2.1 billion in grid upgrades this budget cycle, prioritising disadvantaged areas around Diepsloot and Yeoville to ensure equitable distribution of the benefits," she said. According to City Power, grid improvements have already cut transmission losses by 6% in first half of 2026—a concrete saving that puts Johannesburg in step with advanced systems seen in Singapore’s smart districts.

Measuring Up: Data and Skepticism

The Johannesburg Policy and Analytic Institute released fresh data last week, showing per-capita carbon emissions down to 5.2 tonnes per resident in 2025, compared to 7.1 tonnes in 2020. London and Singapore currently hover just under 5 tonnes per capita. "We're not at parity with the world’s cleanest hubs yet, but the gap is shrinking much faster than before," said Tumelo Mokoena, lead analyst at the Institute. Across the city, private renewable installations have surged: over 18,000 businesses and homeowners have registered rooftop PV systems with City Power since 2023, spurred by incentives and persistent load shedding frustrations.

However, not everyone is convinced the city can keep pace. Louisa de Vries, director at the independent watchdog Joburg Green Futures, warns that lack of skilled technicians and spotty maintenance could stall further progress. "Retrofitting is happening fastest on Maude Street and in upmarket Sandhurst, but Alexandra township and Westbury are far behind on both access and training," she said. City records show over 60% of energy retrofits since 2023 have been concentrated north of the M1 highway.

Next Steps for Residents and Businesses

Looking ahead, officials urge property owners to take advantage of new solar rebates, capped at R8,000 per residential installation, available through the city's Green Energy Rebate Programme from August 1. Businesses within the Rosebank node will be first to trial the linked battery storage pilot run by Emvelo Holdings and the City’s Department of Economic Development. Residents are encouraged to log their energy usage via the MyJoburgSmart app—recently expanded to include carbon tracking features—so that policymakers can refine locality-specific targets ahead of the UN C40 summit due to be hosted at the Sandton Convention Centre in March 2027.

Johannesburg's path toward carbon neutrality is no longer restricted to policy pledges. For businesses on Fredman Drive and residents of Pimville alike, the push to catch up with global benchmarks is becoming a measurable, and increasingly shared, daily reality.
