South Africa’s Government Employees Pension Fund (GEPF), the country’s largest public-sector pension fund and one of the continent’s biggest pools of institutional capital, is facing a broader governance challenge over how environmental, social and governance (ESG) information is assessed, verified and incorporated into investment decisions. With the fund holding more than R2.69 trillion in assets and more than 1.2 million active members, the quality of ESG analysis applied across its investment portfolio has implications well beyond the retirement savings of public servants, extending to South Africa’s capital markets, listed companies, infrastructure financing and the credibility of responsible investment across Africa.

The issue comes as South Africa’s financial regulators and institutional investors increasingly focus on the quality of ESG data supplied by companies, asset managers and specialist ratings providers. The Financial Sector Conduct Authority (FSCA) has published a discussion paper examining ESG rating services and data providers, highlighting concerns around transparency, governance and potential conflicts of interest. The regulator has also incorporated qualitative ESG information into its retirement-funds statistical reporting.

For the GEPF, the challenge is not whether ESG should be considered. Its investment framework already requires environmental, social and governance factors to be incorporated into investment decision-making. The fund’s investment policy also states that its investment managers should integrate ESG considerations and that responsible investment should be aligned with the United Nations-backed Principles for Responsible Investment and South Africa’s Code for Responsible Investing.

The more difficult question is whether the information being used to make those decisions is sufficiently consistent and independently verifiable to support decisions involving billions of rand.

That question has become increasingly important as ESG data has developed into a financial input rather than a specialist sustainability metric. Investors use information about emissions, climate exposure, labour practices, board composition, corruption risks and resource dependence to assess companies’ operational and financial risks. If those data points are incomplete, inconsistent or difficult to compare, the resulting investment assessment can be distorted.

The scale of the GEPF makes that problem particularly consequential. The fund is Africa’s largest public-sector pension fund, with more than 1.267 million active members and more than 565,000 pensioners and beneficiaries, according to its latest published information. Its investment portfolio therefore represents a substantial channel through which domestic savings enter South African companies, infrastructure and financial markets.

The Public Investment Corporation (PIC) manages a significant portion of those assets on behalf of the GEPF. Data published by the Bureau for Economic Research indicates that the PIC had R3.049 trillion in assets under management in 2025, with 87.8% managed for the GEPF. The concentration means that governance and investment decisions made within the two institutions can have consequences across a wide section of South Africa’s financial system.

The PIC already incorporates ESG into its investment process. According to the corporation, its approach includes ESG quality reviews, proxy voting and direct engagement with investee companies. It also requires external fund managers to incorporate responsible ESG practices into their investment processes and uses internal ESG metrics to assess investee companies.

This creates an important distinction between having an ESG framework and demonstrating that the framework produces reliable investment decisions. An institution can have policies requiring ESG integration while still facing challenges in obtaining comparable data from hundreds of companies and external managers operating across different sectors.

For South African pension capital, this is particularly relevant because the portfolio spans industries with very different sustainability risks. Mining companies face exposure to carbon regulation, water scarcity, rehabilitation liabilities and community relations. Banks are exposed indirectly to the environmental and social risks of their borrowers. Property investments face energy-efficiency and climate-resilience considerations, while infrastructure assets can be affected by physical climate risks and changing regulation.
