26. GREEN PROCUREMENT STANDARDS

1. Introduction

Green procurement standards refer to legal and administrative requirements through which public and private organisations incorporate environmental sustainability, energy efficiency, low-carbon technologies, resource conservation, waste reduction and lifecycle environmental impacts into purchasing decisions. In the energy sector, green procurement may cover solar panels, batteries, electric vehicles, energy-efficient equipment, renewable-energy services, construction materials and electricity-supply contracts.

In South Africa, green procurement operates within the constitutional framework of public procurement, sustainable development and environmental protection. It must therefore combine environmental objectives with the constitutional requirements governing public contracts.

2. Constitutional Foundation

Section 217(1) of the Constitution of South Africa, 1996 requires organs of state contracting for goods or services to use a procurement system that is fair, equitable, transparent, competitive and cost-effective. Section 217(2) permits procurement policies incorporating preferences and advancement of persons disadvantaged by unfair discrimination.

Green criteria must therefore be designed so that environmental requirements do not undermine procedural fairness or unlawfully exclude qualified suppliers.

Section 24 of the Constitution provides an additional environmental foundation by recognising the right to an environment that is not harmful to health or well-being and requiring reasonable measures promoting ecologically sustainable development.

3. Statutory Framework

The Preferential Procurement Policy Framework Act 5 of 2000 (PPPFA) historically provided the legislative framework for preferential procurement. It requires organs of state to determine and implement preferential procurement policies within the statutory framework.

The Preferential Procurement Regulations, 2022 subsequently established rules governing the implementation of preferential procurement policies.

South Africa's procurement framework is also undergoing legislative development. The Public Procurement Amendment Bill, 2026 was introduced in Parliament in August 2026 and proposes amendments relating, among other matters, to sustainable-development objectives and procurement policies. Because it remains a Bill rather than enacted legislation, its proposals should not be treated as current binding law.

4. Green Criteria in Energy Procurement

Green procurement standards can be incorporated into tender documentation through objectively measurable criteria such as:

Energy-efficiency performance;

Renewable-energy content;

Carbon emissions over the product lifecycle;

Sustainable materials;

Recyclability and end-of-life management;

Water consumption;

Environmental certification;

Durability and maintenance requirements; and

Climate-resilience characteristics.

For example, a public institution procuring solar equipment could require minimum efficiency, warranty, recyclability and lifecycle-performance standards. Such requirements should be clearly specified before bids are submitted.

The criteria must also be proportionate and technically defensible. An environmental requirement that is vague, discriminatory or unrelated to the procurement objective may expose the tender to judicial review.

5. Energy and Sustainable Development

Green procurement has particular importance in the electricity sector because government procurement can influence the market for renewable energy, energy-efficient technologies, storage systems and low-carbon infrastructure.

However, environmental sustainability does not automatically override other procurement principles. A procuring authority must consider cost-effectiveness, competition, transparency and equal treatment alongside environmental objectives.

The legal objective is therefore not simply to purchase the "greenest" product, but to establish a lawful and transparent procurement methodology in which environmental performance is properly defined and evaluated.

6. Case Law

Case 1: AllPay Consolidated Investment Holdings (Pty) Ltd v CEO of SASSA 2014 (1) SA 604 (CC)

Facts: AllPay challenged the procurement process used for the award of a major social-grant administration contract.

Legal Issue: Whether irregularities in the procurement process rendered the tender constitutionally invalid.

Judgment: The Constitutional Court emphasised that procurement requirements established by the constitutional and legislative framework are legally binding.

Legal Principle / Ratio Decidendi: Compliance with prescribed procurement requirements is not merely an internal administrative preference; it is essential to a constitutionally valid procurement process.

Significance: Green procurement criteria must therefore be incorporated into tender documents and evaluation procedures in a legally compliant manner.

Case 2: Minister of Finance v Afribusiness NPC 2022 (4) SA 362 (CC)

Facts: The case concerned the validity of the Preferential Procurement Regulations, 2017.

Legal Issue: Whether the Minister had exceeded the statutory authority granted by the PPPFA when promulgating aspects of the regulations.

Judgment: The Constitutional Court addressed the relationship between section 217 of the Constitution, the PPPFA and subordinate procurement regulations.

Legal Principle / Ratio Decidendi: Procurement preferences must remain within the constitutional and statutory framework that authorises them.

Significance: Environmental preferences in procurement similarly require a valid legal foundation and cannot be created through administrative action beyond statutory authority.

Case 3: Godimong Consulting Engineers v Mahikeng Local Municipality [2023] ZANWHC 79

Facts: The case concerned compliance with statutory and procurement requirements in a municipal tender.

Legal Issue: Whether mandatory procurement requirements could be disregarded during the tender process.

Judgment: The High Court emphasised the compulsory nature of the constitutional and legislative procurement framework.

Legal Principle: Procurement rules designed to ensure fairness, transparency, competitiveness and cost-effectiveness must be complied with.

Significance: A green tender must apply its environmental specifications consistently to all bidders.

7. Conclusion

Green procurement standards provide a legal mechanism for integrating environmental sustainability into purchasing decisions. In South Africa, their operation is shaped by section 217 of the Constitution, procurement legislation, environmental principles and administrative-law requirements. Effective green procurement requires clear environmental specifications, measurable evaluation criteria, transparency, competition and lawful decision-making. The approach enables public procurement to support sustainable energy infrastructure while preserving the constitutional integrity of the procurement system.
