New Carbon Tax Changes in 2026: Why Solar is Now More Important Than Ever
Carbon Tax Phase 2: What the 2026 Tax Changes Mean for South African Businesses Posted at 09:45 AM SAST, June 4, 2026 by Gavin Thompson, CEO, First Energy Solutions

What’s Changing with Carbon Tax in 2026?
The government is moving into Phase 2 of the Carbon Tax (2026 to 2030). The key updates include:
- Mandatory carbon budgets for large emitters.
- Significantly higher penalties (up to R640 per tonne) if companies exceed their allocated carbon budget.
- Eskom will now pay carbon tax on electricity generation. This cost will ultimately be passed on to businesses and households through higher electricity tariffs.
- Increased opportunities to use carbon offsets to reduce tax liabilities.
These changes are designed to push companies toward lower-carbon operations.
Why This Matters for Your Business
If your company still relies mostly on grid electricity, you could face rising costs in two ways:
- Higher Eskom tariffs as carbon tax costs are passed through to consumers.
- Direct carbon tax penalties if your operations exceed your allocated carbon budget.
Businesses that continue to rely on high electricity consumption from coal-based power face growing financial and compliance pressures from 2026 onwards.
How Solar Power Helps You Navigate These Changes
Installing solar allows your business to:
- Reduce your reliance on Eskom and lower your exposure to future tariff increases driven by carbon tax.
- Generate your own clean electricity and reduce your overall carbon footprint.
- Potentially stay within your carbon budget and avoid heavy penalties.
- Use renewable energy to support your carbon offset strategy.
Many of our clients are already using solar to future-proof their energy costs ahead of these stricter carbon tax rules.
