CBAM and South Africa: How SA Exporters Calculate and Document Their Carbon Liability
South Africa faces significant CBAM exposure across steel, ferrochrome, manganese, cement, and aluminium. The Carbon Tax Act (R236/tCO2) provides a partial offset — but only with verified documentation. This guide covers every step SA exporters must take.
South Africa CBAM Exposure by Sector
| Sector | Key companies | Default (tCO2/t) | Typical actual (tCO2/t) | Annual saving potential |
|---|---|---|---|---|
| Steel (BF-BOF) | ArcelorMittal SA | 2.18 | 1.60–2.00 | EUR 1.2–3.8M per 100,000t |
| Steel (EAF) | Scaw Metals, Cape Gate | 2.18 | 0.70–1.20 | EUR 6.4–9.6M per 100,000t |
| Ferrochrome | Glencore Alloys, Samancor | 2.18 | 0.80–1.50 | EUR 4.4–9.0M per 100,000t |
| Aluminium | Hillside (BHP), Bayside | 12.40 | 8.00–10.00 | EUR 157–288M per 1,000,000t |
| Cement | PPC, Afrisam, Lafarge | 0.766 | 0.55–0.70 | EUR 4.3–13.8M per 1,000,000t |
The Three Gates Framework for SA Exporters
Gate 1 — Calculate: Engage an ISO 14065 accredited verifier to calculate your actual embedded carbon using ISO 14067 methodology. Include Eskom grid factor (0.90 tCO2/MWh) for indirect emissions.
Gate 2 — Document Carbon Tax: Obtain documentation from SARS confirming your Carbon Tax payments. This documentation is required to claim the CBAM deduction under Article 9. The deduction is approximately EUR 12/tCO2 on your verified actual emission value.
Gate 3 — Store: Store your verified embedded carbon record at embeddedcarbonrecord.com. Share the permanent URL with all EU buyers. Register in the O3CI portal for official EU data sharing.
Carbon Tax Deduction Calculation
| Parameter | Value |
|---|---|
| SA Carbon Tax rate (Phase 2, 2026) | ZAR 236/tCO2 ≈ EUR 12/tCO2 |
| CBAM certificate price | EUR 65.42/tCO2 |
| Carbon Tax deduction (if eligible) | EUR 12/tCO2 on verified actual emissions |
| Net CBAM cost after deduction | EUR 53.42/tCO2 on verified actual emissions |
| Deduction requires | Verified documentation of Carbon Tax payments |
Frequently Asked Questions
Does South Africa's Carbon Tax offset CBAM?
Yes, partially. The Carbon Tax (ZAR 236/tCO2 ≈ EUR 12/tCO2) can be deducted from CBAM certificate costs under Article 9 — but only with verified documentation of Carbon Tax payments.
What is Eskom's grid emission factor for CBAM calculations?
Eskom's grid emission factor is approximately 0.90 tCO2/MWh — one of the highest in the world due to South Africa's coal-dominant electricity generation.
Which South African sectors face the highest CBAM exposure?
EAF steel producers, ferrochrome producers, and aluminium smelters face the highest exposure due to Eskom's coal-heavy grid. ArcelorMittal SA, Scaw Metals, Glencore Alloys, and Hillside Aluminium are key affected companies.
What is the CBAM impact on South African ferrochrome exports?
South Africa is the world's largest ferrochrome producer. Ferrochrome is covered under CBAM as a ferro-alloy (CN code 7202). At the default of 2.18 tCO2/t and EUR 65.42/tCO2, the CBAM certificate cost is EUR 142.62/t.
Where can South African manufacturers find ISO 14065 accredited CBAM verifiers?
See the South Africa verifier directory at /verification-directory/south-africa/ for SANAS ISO 14065 accredited CBAM verification firms.
