CLIMATE LIABILITY EXPOSURE IN ENERGY INVESTMENTS

1. Introduction

Climate liability exposure in energy investments refers to the legal and financial risks faced by investors, energy companies, lenders, directors, governments, and project developers because an energy investment contributes to climate change, fails to comply with climate regulation, or becomes inconsistent with evolving environmental obligations. This issue is particularly significant for investments in coal, oil, gas, electricity generation, pipelines, and other carbon-intensive infrastructure.

Climate liability is no longer limited to penalties for direct pollution. It may arise through environmental legislation, administrative law, constitutional rights, corporate governance duties, disclosure requirements, contractual obligations, tort or delict claims, and judicial review of project approvals. Consequently, climate risk has become an important component of energy investment due diligence.

2. Sources of Climate Liability

Energy investments can create several forms of liability. Regulatory liability may arise where a project violates emission limits, environmental authorisations, carbon-pricing requirements, or licensing conditions. Civil liability can arise where emissions or environmental damage cause legally recognised harm.

Investors also face transition liability and financial exposure. Governments may introduce stricter carbon standards, renewable-energy requirements, carbon taxes, or restrictions on fossil-fuel infrastructure. These measures can reduce the profitability of existing investments and contribute to stranded assets.

Furthermore, companies may face liability for misleading statements concerning emissions reductions, carbon neutrality, sustainability, or climate-related investment characteristics.

3. Climate Risk and Environmental Authorisation

In South Africa, climate considerations interact with section 24 of the Constitution, which protects the right to an environment that is not harmful to health or well-being and requires reasonable measures to protect the environment for present and future generations.

The National Environmental Management Act 107 of 1998 (NEMA) establishes environmental management principles applicable to environmentally significant projects. Energy developers must therefore consider environmental and climate consequences when seeking authorisation.

Climate exposure is especially important for long-lived infrastructure because investment decisions made today may generate emissions and regulatory consequences for several decades.

4. Case Law – Earthlife Africa Johannesburg v Minister of Environmental Affairs (Thabametsi Case) [2017] ZAGPPHC 58

Facts: The dispute concerned environmental authorisation for the proposed Thabametsi coal-fired power station. Earthlife Africa argued that the authorities had failed adequately to assess the project's climate-change consequences.

Legal Issue: Whether climate-change impacts had to be considered when determining whether environmental authorisation should be granted.

Judgment: The High Court held that climate impacts were relevant considerations under South African environmental law and that an appropriate climate-change impact assessment was necessary.

Legal Principle / Ratio Decidendi: Decision-makers considering environmentally significant energy infrastructure must properly evaluate climate impacts as part of environmental decision-making.

Significance: The judgment demonstrates that inadequate climate assessment can expose energy projects to judicial review, delay, additional assessment requirements, increased costs, and potentially stranded investment.

5. Case Law – Sustaining the Wild Coast NPC v Minister of Mineral Resources and Energy [2022] ZAECHC 55

Facts: The case concerned seismic exploration activities undertaken in connection with offshore oil and gas exploration along South Africa's Wild Coast. Environmental organisations and affected communities challenged the relevant exploration arrangements.

Legal Issue: Whether environmental, community, consultation, and constitutional considerations had been adequately addressed.

Judgment: The High Court reviewed and set aside the exploration right on grounds including deficiencies in consultation and consideration of relevant environmental interests.

Legal Principle / Ratio Decidendi: Energy and extractive investments must comply with environmental governance and meaningful consultation requirements; commercial investment expectations cannot displace statutory and constitutional obligations.

Significance: The case illustrates how failures during project approval can generate substantial regulatory, litigation, reputational, and investment exposure.

6. Comparative Case – Milieudefensie v Royal Dutch Shell

Facts: Environmental organisations and individuals brought proceedings against Shell concerning the climate consequences associated with the company's activities and value-chain emissions.

Legal Issue: Whether private-law duties could require a major energy company to reduce greenhouse-gas emissions.

Judgment: In 2021, the Hague District Court ordered significant emissions reductions. However, in 2024 the Hague Court of Appeal overturned the specific 45% reduction order, while recognising that companies can have responsibilities concerning dangerous climate change.

Legal Principle / Ratio Decidendi: Climate-related corporate duties may develop through private law, but the precise content and enforceability of particular emissions-reduction obligations depend on the applicable legal framework and evidence.

Significance: The litigation demonstrates that climate exposure can extend beyond regulatory compliance into corporate strategy and civil litigation.

7. Conclusion

Climate liability has become a material component of modern energy investment risk. Investors must evaluate emissions exposure, environmental approvals, climate regulation, community rights, corporate disclosures, litigation risk, and stranded-asset potential before committing capital. Cases such as Earthlife Africa, Sustaining the Wild Coast, and Milieudefensie demonstrate that climate considerations increasingly affect project legality and investment security. Effective climate due diligence is therefore essential for legally resilient and financially sustainable energy investment.
