The Debate Ignites: Calls for Carbon Tax Suspension
South Africa's energy landscape is under intense scrutiny as Electricity and Energy Minister Kgosientsho Ramokgopa proposes a temporary suspension of the country's carbon tax. This move, reported in early February 2026, stems from mounting pressures on electricity tariffs and the financial burdens faced by state-owned utility Eskom, which anticipates a R5.5 billion carbon tax liability for the 2026 financial year.
The carbon tax, introduced via the Carbon Tax Act of 2019 and effective from June 2020, embodies the 'polluter pays' principle. It levies charges on greenhouse gas emissions from fossil fuel combustion, starting at R120 per tonne of CO2 equivalent (CO2e), though offsets and allowances reduced effective rates to R6-R48 per tonne for many emitters. Phase Two, commencing January 2026, promises escalations to incentivize cleaner practices. Yet, with annual revenues around R1.5 billion—comparable to early childhood development grants—the tax's role in funding social programs is now at risk.
UCT Researchers' Strong Advocacy for Retention
Enter researchers from the University of Cape Town (UCT), particularly from its Energy Research Centre (ERC), who have vehemently opposed the suspension in a timely op-ed published on February 24, 2026, in The Conversation and republished on UCT News. Led by experts like Britta Rennkamp, Andrew Marquard, Gina Ziervogel, Harald Winkler, Mark New, Melanie Murcott, Ralph Hamann, and Wikus Kruger, the piece draws on decades of climate policy research to argue that retaining the tax is essential for justice, economy, and environment.
These UCT academics, with deep roots in climate science, governance, and law, emphasize that suspension would unlawfully bypass parliamentary legislation, undermine the 2024 Climate Change Act, and violate constitutional rights to a healthy environment (Section 24). Their intervention highlights UCT's longstanding leadership in energy transition studies, including economic modeling of carbon pricing since 2008.
A Brief History of South Africa's Carbon Tax Journey
South Africa's carbon tax emerged from over a decade of stakeholder negotiations, culminating in the 2019 Act amid Paris Agreement pressures. Modeled after global best practices, it covers about 80% of national emissions, primarily from energy sectors like coal-dependent electricity (over 80% of supply). Initial implementation saw compromises: basic tax rebates (up to 95% for process emissions) and trade exposure allowances softened impacts on trade-exposed industries.
By 2025, the tax generated modest revenues while signaling commitment to decarbonization. Phase Two (2026-2030) ramps up rates, removes some offsets, and introduces performance allowances tied to emission benchmarks. UCT's ERC contributed pivotal analyses, such as economic implications studies showing minimal GDP hits (under 1%) with revenue recycling into green investments.
Economic Impacts: Revenue, Jobs, and Competitiveness
Critics claim the tax stifles growth, but UCT data counters this: revenues fund social goods, equating R1.5 billion to vital grants, while fostering cleaner tech innovation. Studies project job creation in renewables—South Africa's Just Energy Transition Partnership (JETP) eyes 300,000 green jobs by 2030.Carbon Tax Act Suspension risks revenue loss and export penalties under the EU's Carbon Border Adjustment Mechanism (CBAM), hitting steel and cement exporters hard.
- Annual revenue: R1.5bn, recyclable for low-income energy subsidies.
- Innovation boost: Taxes spur R&D in low-carbon processes, attracting FDI.
- Job shift: From coal (phase-out by 2050) to solar/wind, with training via universities like UCT.
- GDP safeguard: Climate inaction could cost 3.6% GDP/year via droughts, floods.

Aligning with Paris Agreement and NDCs
South Africa's Nationally Determined Contribution (NDC), updated October 2025, targets 350-420 MtCO2e by 2030 (down from business-as-usual), with carbon tax as a cornerstone mitigation tool. Ratifying the Paris Agreement binds the nation to ratchet up ambitions every five years. UCT experts warn suspension erodes credibility, jeopardizing JETP's $8.5 billion pledge for coal phase-out.
The 2024 Climate Change Act mandates sector emission targets, integrating tax as 'reasonable legislative measures' per Constitution. Global context: 20% emissions priced, SA's low effective rate (0.1-0.5% fossil fuel costs) lags peers like Sweden (R500+/tonne).

| Year | NDC Target (MtCO2e excl. LULUCF) | Carbon Tax Role |
|---|---|---|
| 2025 | 398-510 | Peak/plateau emissions |
| 2030 | 350-420 | Decline trajectory |
The Polluter Pays Principle in Practice
At its core, the tax internalizes emissions externalities: high emitters (e.g., Eskom, Sasol) face costs proportional to pollution. UCT models show behavioral shifts—firms invest in efficiency, renewables. Revenue recycling offsets regressivity: rebates for poor households, green subsidies. Step-by-step: (1) Emit CO2e → (2) Calculate taxable fuel use → (3) Apply rate minus allowances → (4) Pay SARS → (5) Govt reallocates to just transition.
Cultural context: In coal-reliant Mpumalanga, tax funds retraining via TVETs and universities, easing worker transitions.
Fostering Innovation and Green Jobs
Carbon pricing drives R&D: post-tax, SA solar capacity tripled. UCT research highlights innovation spillovers—e.g., Sasol's green hydrogen pilots. Jobs: Renewables employ 3x more per MW than coal. Higher ed angle: Programs like UCT's MSc Energy Studies train experts; South Africa university jobs in climate tech abound.
- Risk: Fossil lock-in delays jobs.
- Benefit: 1M green jobs by 2030 per PC Commission.
- Example: Eskom's 100MW solar offset tax via offsets.
Global Trade Risks: CBAM and Beyond
EU CBAM (2026 full) taxes imports sans equivalent pricing—SA steel faces 20-35% duties sans tax. Retention proves compliance, averting R10bn+ losses. IMF notes carbon prices enhance competitiveness long-term.EU CBAM
Legal and Constitutional Imperatives
Suspension contravenes separation of powers—executive can't override Act without repeal. Aligns with Bill of Rights: 'reasonable measures prevent pollution.' UCT law experts cite jurisprudence upholding env rights.
Stakeholder Perspectives and Challenges
Business Unity SA seeks offsets; Greenpeace demands hikes; unions fear jobs but back JETP. Challenges: Admin burdens, evasion. Solutions: Digital SARS tracking, revenue transparency.

Phase Two Outlook and Policy Recommendations
Phase Two tightens allowances (60-80%), adds offsets expansion. UCT urges: Recycle 100% revenue greenly, link to NDC monitoring. With Budget 2026 looming, retention signals fiscal prudence amid debt-service costs (20% budget).
Implications for Higher Education and Careers
UCT's advocacy spotlights academia's policy influence. Aspiring researchers: Pursue higher ed jobs in sustainability. Rate professors via Rate My Professor; seek career advice. Internal links to university jobs, post a job drive engagement.
In conclusion, UCT researchers' call underscores retaining the carbon tax as pivotal for SA's equitable low-carbon future. Policymakers must prioritize evidence over lobbies for sustainable prosperity.
