Coal phase-out delays could cost SA 32,000 lives, report warns

Trapped in the Smoke Stack

Mpumalanga’s skyline is a lattice of cooling towers and conveyor belts. Fifteen state-run stations - conceived in the 1970s - still push more than eighty percent of the nation’s electricity across pylons that crackle from the Cape winelands to the Limpopo citrus belt. The 2011 Integrated Resource Plan set a 2019 shutdown for most of these giants, but after 2023’s record black-outs the cabinet quietly rubber-stamped new calendars. Fourteen plants will burn longer, and the Kendal and Matla blocks received formal permission to run until 2050, a full decade after their original expiry date.

A child in Soweto has never seen the Milky Way. Winter nights are cloaked in amber haze as temperature inversions pin the exhaust from distant stacks above Johannesburg’s 15 million residents. Satellite photographs taken in June 2023 show a rust-coloured lid settled between the Magaliesberg ridge and the Witwatersrand escarpment, a lid traced by University of Pretoria isotopic work to the Kendal, Duvha and Kriel stations 120 km away.

The revised timetable did not arrive with new filters. Greenpeace, the Centre for Research on Energy and Clean Air and the Durban-based NGO GroundWork ran the revised burn schedule through open-path dispersion models and the Global Burden of Disease toolkit. Their numbers translate extra megawatts into human lives.

Grim Figures Hidden in Winter Fog

Their projections isolate the surge in fine particulate matter (PM2.5), sulphur dioxide and nitrous oxides and feed them into health curves calibrated for South African age and income distribution. The tally runs from 2025 to 2050:

• 32,000 South African adults will die earlier than they otherwise would; 15,000 of these deaths will occur in Gauteng, a province without a single coal burner.
• 41,000 babies will arrive too soon, the result of maternal exposure to those invisible specks.
• Every decade will add another 17,000 cases of childhood asthma.
• By 2040, roughly 370 children under the age of five will die each year; most will live in townships such as Soweto, Tembisa and Katlehong that sit directly beneath the pollution corridors.

Those are conservative end-points. The model omits cancer linked to coal ash seepage, mercury that rides the plumes into the food chain and the heat-island effect that amplifies late-afternoon ozone spikes.

The Price Tag on Postponement

Premature funerals and chronic lung disease come with invoices. The researchers translated every lost life and sick day into rands using World Bank value-of-statistical-life figures adjusted for South African income. The tally reaches 721 billion rand (roughly 38 billion US dollars) between now and 2050. That ledger covers two million extra sick-leave days and a 14 % jump in public pharmaceutical procurement. Another unpublished annex finds that coal-fired sulphate aerosols cut summer rainfall in the interior by 3–4 %, slicing 0.2 % off annual farm GDP.

Daily Life under the Plume

Middelburg, Mpumalanga

Sharon Mbonani wipes soot from her windowsill each dawn before she wakes her son. The boy is one year old and has already spent two nights in hospital on a nebuliser. Doctors advised her to send him to his grandparents in the Eastern Cape; she did, and now she sees him only on weekends. On the day the Greenpeace study was released, nine other mothers in the Siyanqoba informal settlement told nearly identical stories. Clinic intake forms obtained by GroundWork confirm a four-fold rise in respiratory diagnoses since 2015, the same period in which Eskom ramped up coal output to keep the lights on during load-shedding shifts.

When Diplomacy Meets Debt

At COP26 in Glasgow South Africa became the poster-child for a new climate finance tool: the Just Energy Transition Partnership. France, Germany, the United Kingdom, the United States and the European Union pledged 8.5 billion dollars in concessional loans and grants to retire coal early, bolster the grid and retrain miners. By mid-2023 only one billion had left donor accounts, mostly for a battery-storage tender. A change in the United States Congress froze another 600 million, while Eskom’s 423 billion rand debt strangles its balance sheet and domestic-content quarrels stall solar procurement. Without new transmission corridors the Northern Cape’s sun remains a stranded asset.

Workforces, Courtrooms and Wires

National Union of Mineworkers members argue that shutting plants betrays workers who powered apartheid-era factories and post-1994 electrification alike. Their “slow-coal” plan would retrofit plants with carbon-capture gear. Analysts counter that fitting even one 2,000 MW unit with amine scrubbers would cost 30 billion rand yet trim national emissions by less than one percent. The younger Association of Mineworkers and Construction Union is already organising rooftop-solar cooperatives on disused mine land, claiming reskilling can outpace ministerial pessimism.

In March 2024 the Centre for Environmental Rights filed a High Court challenge questioning the legality of the life-extension approvals, arguing that climate impacts were never considered in the environmental authorisation process. Eskom’s lawyers warn that enforced shutdowns could trigger “unconstitutional load-shedding,” setting up a constitutional clash between the right to a healthy environment and the right to electricity.

Three Roads to the Mid-Century

Scenario A – “Coal-Plus” keeps plants spinning past their sell-by date. Burn rates rise 8 % above 2023 levels, annual black-outs ease marginally, but excess deaths rise to 52,000 by 2050. Eskom’s SO₂ and NOₓ liabilities breach World Bank lending thresholds as early as 2029.

Scenario B – “Conditional Green” revives the JETP at two billion dollars a year, steers six stations into retirement by 2032 and accelerates 14,000 km of new transmission. Mortality falls to 19,000 excess deaths; utility debt drops below 300 billion rand.

Scenario C – “Litigation Shock” begins with a court order forcing immediate compliance with minimum emission standards. Kendal, Duvha, Kriel and Matimba close within 24 months. Emergency rooftop PV and demand-response programmes blunt blackout severity; within three years air-quality gains deliver measurable health savings in a route reminiscent of Ontario’s 2003–2014 coal exit.

Voices from the Ground

• Sipho Mahlangu, 58, turbine operator at Kendal for 34 years: “My son builds wind towers near Cape Town. He earns more than I ever did. Transition is real if we stop pretending it isn’t.”
• Dr. Lwazi Mbatha, head of paediatrics at Chris Hani Baragwanath Hospital: “This winter RSV season arrived six weeks early. Chronic pollution is making our kids sitting ducks for any passing virus.”
• Tumi Maleka, 27, community liaison for a Soweto solar cooperative: “We have 1.2 MW on school roofs. Another 4 MW is ready to go if Eskom drops its wheeling tariff from 40 cents to 10.”

Mercury, Ash and Last-Mile Hurdles

South Africa’s coal furnaces vent 25 tonnes of mercury each year. Isotopic studies in trout above the Vaal dam reveal methylmercury levels 3.4 times above the WHO provisional safe intake for pregnant women. Imported Indian coal, blended at stations such as Majuba, carries three times the mercury of local grades, compounding the neuro-toxic risk.

For every tonne of coal burnt, 0.3 tonnes of fly ash remain. Over 1.6 billion tonnes have piled into unlined dumps, leaching chromium, arsenic and boron into aquifers. The Council for Geoscience lists 45 high-risk ash dams within 500 metres of settlements; 12 sit upstream of drinking-water intakes.

When Transnet closed a 90 km stretch of the Maputo corridor for track repairs in April 2024, Eskom’s coal stockpile shrank to eleven days. Spot prices for 4,800 kcal coal soared to 190 dollars per tonne, making the marginal cost of solar and wind - already zero - financially decisive even to the most coal-faithful boardrooms.

From Policy Papers to Playgrounds

On 14 June 2024 the Right2Know Campaign will march to the Union Buildings inflating a 15-metre black lung. On the same day the Soweto Solar Cooperative will mount its 100 kW photovoltaic array on Diepkloof Primary’s roof, a living rebuttal to claims that alternatives do not exist.

Proposals now circulate in Treasury corridors and parliamentary committees: a coal-mortality tax of 120 rand per tonne of unabated SO₂, a climate-health bond that links coupon payments to hospital admission rates, an early-retirement bonus for workers over 55 financed by diesel-peaker savings, and even a cross-provincial pollution protocol modelled on Europe’s 1979 Geneva Convention.

Yet policy can move only as fast as data. South Africa’s last National Burden of Disease study dates to 2000; 22 % of adult death certificates are missing and air-quality monitors cover 0.4 % of the land. New 1-kilometre satellite maps promise daily exposure layers with 72-hour updates. Preliminary runs suggest the official death toll may already understate coal-linked mortality by 28 %.

Beyond the power sector sits Sasol’s Secunda complex, the planet’s single-largest coal-to-liquids installation, venting 57 million tonnes of CO₂-e each year - more than every passenger car in the country. Sasol’s 2030 decarbonisation roadmap swaps 20 % of coal feedstock for green hydrogen, but it hinges on a 400 km CO₂ pipeline whose permitting timeline rivals the grid-strengthening debate.

Until the pipeline, the turbines, the court rulings and the rooftop panels shift in concert, the coal stacks will keep sending their invisible cargo eastward. Each extra megawatt-hour is bought with wheezing infants, lost work days and a debt that compounds in lungs and balance sheets alike.

[{"question": "

What are the health consequences of South Africa's reliance on coal?

", "answer": "South Africa's continued coal use is projected to lead to severe health issues. By 2050, it is estimated to cause 32,000 premature adult deaths, 41,000 preterm births due to maternal exposure to pollutants, and 17,000 new cases of childhood asthma. Specific areas like Gauteng, despite not having coal burners, are expected to experience 15,000 of these adult deaths due to pollution corridors. Furthermore, by 2040, approximately 370 children under the age of five are projected to die annually, predominantly in townships directly beneath pollution pathways. This pollution also leads to increased respiratory illnesses in children, as seen in areas like Siyanqoba informal settlement where clinics report a four-fold rise in respiratory diagnoses since 2015."}, {"question": "

What are the economic costs associated with South Africa's continued coal usage?

", "answer": "The economic burden of South Africa's coal reliance is substantial, estimated at 721 billion rand (approximately 38 billion USD) by 2050. This cost accounts for increased healthcare expenses, productivity losses due to illness and premature deaths, and reduced agricultural output. The country faces an additional two million sick-leave days and a 14% increase in public pharmaceutical procurement. Moreover, coal-fired sulphate aerosols are found to reduce summer rainfall in the interior by 3-4%, leading to a 0.2% annual cut in farm GDP."}, {"question": "

Why is South Africa still so dependent on coal for electricity, despite the known risks?

", "answer": "South Africa's electricity grid is heavily reliant on coal-fired power plants, with fifteen state-run stations, many conceived in the 1970s, still generating over 80% of the nation's electricity. While the 2011 Integrated Resource Plan aimed for a 2019 shutdown of most of these plants, record blackouts in 2023 led to a quiet approval for fourteen plants to operate longer. Specifically, Kendal and Matla blocks received permission to run until 2050, a decade beyond their original expiry. This continued reliance is partly due to the challenges of transitioning to renewables, including Eskom's significant debt (423 billion rand) which hinders investment, and issues like the lack of new transmission corridors that leave solar energy in the Northern Cape as a stranded asset."}, {"question": "

What impact does coal pollution have on air quality and visibility in South Africa?

", "answer": "Coal pollution significantly degrades air quality and reduces visibility, particularly in densely populated areas. For instance, children in Soweto reportedly 'have never seen the Milky Way' due to the amber haze, especially during winter nights when temperature inversions trap exhaust from distant power plants. Satellite photographs from June 2023 clearly show a rust-colored lid of pollution settled between the Magaliesberg ridge and the Witwatersrand escarpment, directly linked to emissions from stations like Kendal, Duvha, and Kriel up to 120 km away. This pollution consists of fine particulate matter (PM2.5), sulfur dioxide, and nitrous oxides."}, {"question": "

What is the 'Just Energy Transition Partnership' and how has it fared in South Africa?

", "answer": "The Just Energy Transition Partnership (JETP) is a climate finance initiative where France, Germany, the United Kingdom, the United States, and the European Union pledged $8.5 billion in concessional loans and grants to South Africa at COP26. The goal was to facilitate an early retirement of coal plants, strengthen the grid, and retrain miners. However, by mid-2023, only $1 billion had been disbursed, primarily for a battery-storage tender. An additional $600 million was frozen due to changes in the US Congress, and Eskom's massive debt, along with domestic-content disputes, has further stalled progress. This has limited the JETP's effectiveness in accelerating South Africa's transition away from coal."}, {"question": "

What are some potential pathways or solutions for South Africa to transition away from coal?

", "answer": "Several pathways are being considered for South Africa's energy transition. \"Conditional Green\" scenario involves reviving the JETP with $2 billion annually, retiring six coal stations by 2032, and accelerating 14,000 km of new transmission lines, which could reduce excess deaths to 19,000. Another, \"Litigation Shock,\" proposes court-ordered compliance with minimum emission standards, forcing the closure of major plants like Kendal and Matimba within 24 months, with emergency rooftop PV and demand-response programs mitigating blackouts. Grassroots initiatives, such as the Association of Mineworkers and Construction Union organizing rooftop-solar cooperatives on disused mine land, and the Soweto Solar Cooperative installing photovoltaic arrays on school roofs, demonstrate that alternatives exist. Policy proposals include a coal-mortality tax, climate-health bonds, and early-retirement bonuses for coal workers. However, challenges remain, including the need for better data on air quality and disease burden, and addressing large industrial emitters like Sasol's Secunda complex."}]
