CLIMATE LITIGATION AGAINST ELECTRICITY COMPANIES

1. Meaning and Scope

Climate litigation against electricity companies refers to legal proceedings seeking to hold electricity generators, utilities, project developers, or related public authorities accountable for activities contributing to greenhouse-gas emissions, climate change, environmental degradation, or inadequate climate-risk management. The issue is particularly significant for coal- and other fossil-fuel-based electricity generation because power stations can operate for decades and create long-term emissions consequences.

Climate litigation may arise through constitutional law, environmental law, administrative review, tort or delict, corporate law, human-rights law, disclosure obligations, and environmental-impact-assessment procedures. Claimants commonly include environmental organisations, affected communities, individuals, shareholders, and public-interest bodies.

2. Legal Basis of Climate Claims

Electricity companies are usually subject to environmental authorisation, emissions controls, licensing requirements, and increasingly climate-related regulatory obligations. Litigation may challenge either the company's conduct directly or the governmental decision permitting an electricity project.

In South Africa, section 24 of the Constitution establishes environmental rights, while the National Environmental Management Act 107 of 1998 (NEMA) provides an important framework for environmental decision-making. NEMA requires relevant environmental impacts and reasonable mitigation measures to be considered when environmental authorisation is granted.

Climate litigation therefore connects electricity regulation with principles such as sustainable development, precaution, intergenerational equity, environmental justice, administrative legality, and public participation.

3. Climate Impact Assessment

One major litigation issue concerns whether regulators adequately considered the lifetime climate effects of proposed electricity infrastructure. Assessment may involve the quantity of greenhouse gases generated during construction, operation and decommissioning, available mitigation measures, alternative technologies, and the project's resilience to climate-related conditions such as drought and water scarcity.

A regulator cannot necessarily rely solely upon broad national electricity policy where environmental legislation requires consideration of the project-specific impacts of an individual power station.

4. Case Law – Earthlife Africa Johannesburg v Minister of Environmental Affairs

Case Name/Citation: Earthlife Africa Johannesburg v Minister of Environmental Affairs and Others (65662/16) [2017] ZAGPPHC 58; [2017] 2 All SA 519 (GP).

Facts: The dispute concerned the proposed 1,200 MW Thabametsi coal-fired power station near Lephalale, Limpopo. Environmental authorisation had been granted even though the project's climate-change consequences had not been comprehensively assessed. Earthlife Africa challenged the governmental decisions authorising the project.

Legal Issue: Whether climate-change impacts were relevant considerations that had to be properly investigated and considered before environmental authorisation for a major coal-fired electricity project could lawfully be approved.

Judgment: The High Court concluded that climate impacts were relevant considerations under NEMA. It found that the project's climate consequences had not been adequately considered before authorisation and reviewed the Minister's decision accordingly.

Legal Principle/Ratio Decidendi: Environmental decision-makers must consider relevant climate-change impacts when assessing projects capable of producing substantial greenhouse-gas emissions. The court explained that assessment logically includes the project's contribution to climate change, its vulnerability to climate effects, and possible measures to avoid, mitigate or remedy those impacts.

Significance: The judgment is particularly important for electricity companies because it demonstrates that obtaining approval for carbon-intensive generation requires meaningful consideration of project-specific climate consequences. General electricity-security policies do not automatically eliminate environmental assessment duties.

5. Corporate and Operational Responsibility

Climate litigation can also focus upon how electricity companies operate existing assets. Potential disputes may involve alleged failure to comply with emissions licences, misleading climate disclosures, inadequate transition planning, or failure to account for foreseeable environmental risks.

However, establishing corporate liability is legally complex. A claimant ordinarily needs an identifiable legal duty, breach, standing, causation, and an available remedy. Climate change results from cumulative global emissions, making attribution and causation particularly difficult in damages litigation. Regulatory and administrative proceedings can therefore sometimes provide more direct mechanisms for challenging high-emission electricity projects.

6. Electricity Security and Climate Protection

Courts may encounter tension between security of electricity supply and climate protection. In Earthlife Africa, government arguments included South Africa's electricity requirements and continued reliance on coal. The judgment nevertheless distinguished broad energy-policy choices from the legal requirement to consider the environmental consequences of a particular project.

This distinction is important: climate litigation does not automatically require courts to determine national electricity policy. Instead, courts may examine whether statutory procedures were followed, relevant climate evidence was considered, and administrative decisions were lawful, rational and procedurally fair.

7. Conclusion

Climate litigation is becoming an important mechanism for scrutinising electricity-sector decisions. It can require electricity companies and regulators to address greenhouse-gas emissions, climate resilience, environmental impacts, mitigation alternatives and long-term transition risks. Earthlife Africa illustrates how climate considerations can become legally mandatory within environmental authorisation processes. Consequently, climate governance increasingly operates not merely as policy but as a significant component of electricity regulation, corporate responsibility and environmental accountability.
