20. FUTURE OF PETROLEUM REGULATION IN NET-ZERO ECONOMIES

1. Introduction

The transition toward net-zero economies is transforming petroleum regulation. Traditionally, petroleum law concentrated on exploration rights, production licences, state royalties, energy security, and environmental protection. In a net-zero framework, regulators must additionally consider greenhouse-gas emissions, climate commitments, carbon budgets, stranded assets, methane emissions, decommissioning, and the compatibility of new petroleum projects with long-term decarbonisation.

Petroleum regulation is therefore unlikely simply to disappear. Instead, it is developing from a system primarily facilitating extraction into a framework that increasingly regulates the full climate and environmental consequences of fossil-fuel development.

2. Petroleum Regulation and Climate Governance

Future regulatory systems are likely to integrate petroleum licensing with climate law and environmental impact assessment. Before approving exploration or production, authorities may increasingly need to evaluate the project's expected emissions, environmental effects, economic benefits, energy-security implications, and consistency with national climate policies.

In South Africa, section 24 of the Constitution protects the right to an environment that is not harmful to health or well-being and requires environmental protection for present and future generations through reasonable legislative and other measures. The National Environmental Management Act 107 of 1998 (NEMA) establishes sustainable-development principles relevant to environmentally significant projects.

Courts have emphasised that environmental protection and development must be considered together rather than treated as completely separate objectives.

3. Major Features of Future Regulation

Net-zero petroleum regulation is likely to place greater emphasis on carbon-intensity standards, methane monitoring, environmental authorisations, financial provision for rehabilitation, carbon pricing, and decommissioning obligations.

Regulators may also demand greater disclosure of lifecycle emissions and climate-related risks before approving petroleum projects. Companies could consequently face stronger obligations covering the entire petroleum lifecycle—from exploration and extraction through transportation, refining, eventual closure, and environmental rehabilitation.

A particularly important question will be whether authorisation processes adequately consider downstream or indirect emissions associated with ultimately using extracted petroleum.

4. Case Law: Sustaining the Wild Coast NPC v Minister of Mineral Resources and Energy

Case Name/Citation: Sustaining the Wild Coast NPC and Others v Minister of Mineral Resources and Energy and Others [2022] ZAECMKHC 55; 2022 (6) SA 589 (ECMk), with the subsequent appeal reported as Minister of Mineral Resources and Energy v Sustaining the Wild Coast NPC [2024] ZASCA 84.

Facts: An exploration right permitted petroleum exploration off South Africa's Wild Coast, including a proposed seismic survey. Coastal communities and environmental organisations challenged the legality of the authorisation process. The communities relied upon environmental interests as well as livelihood, cultural, spiritual, and customary connections with the ocean.

Legal Issue: Whether the petroleum exploration right had been lawfully granted, including whether affected communities had been adequately consulted and whether relevant environmental and climate considerations had received proper attention.

Judgment: The High Court set aside the exploration right. Among the deficiencies identified were inadequate consultation with affected communities and failures concerning relevant environmental considerations. The Supreme Court of Appeal subsequently dealt with the challenge in 2024.

Legal Principle/Ratio Decidendi: Petroleum-resource development must comply with administrative justice, meaningful consultation, environmental protection, and sustainable-development requirements. Resource development cannot be considered independently from its broader environmental and social consequences.

Significance: The case illustrates how future petroleum authorisations may face increasingly intensive scrutiny concerning climate impacts, community participation, environmental sustainability, and constitutional rights.

5. Case Law: Fuel Retailers Association v Director-General

Case Name/Citation: Fuel Retailers Association of Southern Africa v Director-General: Environmental Management 2007 (6) SA 4 (CC).

Facts: The dispute concerned environmental approval for constructing a filling station. The applicants argued that relevant authorities had failed properly to consider environmental and socio-economic aspects of sustainable development.

Legal Issue: Whether environmental authorities were required to consider the relationship between environmental protection and socio-economic development.

Judgment: The Constitutional Court stressed that sustainable development integrates environmental protection with socio-economic development. This principle has subsequently remained important in South African environmental jurisprudence.

Legal Principle/Ratio Decidendi: Development decisions must integrate environmental, social, and economic considerations rather than treating environmental protection as an afterthought.

Significance: For future petroleum regulation, the principle supports comprehensive assessment of extraction projects within wider sustainability and climate-transition objectives.

6. Just Transition and Petroleum Communities

Net-zero regulation must also address workers and communities economically dependent on petroleum activities. A just transition may require retraining programmes, economic diversification, social protection, community participation, and carefully managed closure of petroleum infrastructure.

Governments must therefore balance decarbonisation, energy security, employment, affordability, environmental protection, and intergenerational justice.

7. Conclusion

The future of petroleum regulation in net-zero economies involves a transition from traditional extraction-focused regulation toward climate-integrated resource governance. Licensing, environmental assessment, emissions regulation, public participation, corporate accountability, and decommissioning will become increasingly interconnected. Cases such as Sustaining the Wild Coast demonstrate that petroleum development already operates within constitutional, administrative, and environmental constraints. Net-zero governance will intensify the need for petroleum decisions to reconcile remaining energy needs with climate obligations, sustainable development, community rights, and long-term environmental protection.
