Navigating Muddy Waters

This report, the final part of a five-part series by WWF South Africa, SinCo, Carbon Tracker, and Trucost, synthesizes research on the financial risks and opportunities associated with carbon emissions and water scarcity for institutional investors in South Africa. It argues that many investors are 'universal owners' whose returns depend on the overall health of the economy, making them vulnerable to systemic risks from climate change and water stress. The report finds that carbon and water risks are largely mispriced in the market, with significant exposure in the energy and mining sectors, and calls for regulatory interventions and a shift toward low-carbon, water-responsible investment strategies to avoid stranded assets and ensure long-term returns.

• Institutional investors in South Africa, particularly large pension funds and insurance companies, act as 'universal owners' whose fiduciary obligations and returns are critically dependent on the performance of the overall economy, making them vulnerable to systemic risks from climate change and water scarcity.
• There is significant evidence that investors are not pricing climate change and freshwater risks into their decisions, leading to mispriced assets and potential systemic risk. More than half of surveyed institutional investors have not priced greenhouse gas emissions, and water scarcity risks are not substantively mapped at the portfolio level.
• The electricity sector is the primary source of carbon risk in South Africa, with the energy industry accounting for 71% of the country's greenhouse gas emissions. However, institutional investment in renewable energy is limited by a lack of investment-grade products, a low government target of 9% for new renewable generation by 2030, and regulatory barriers for independent power producers.
• A proposed carbon tax of R120 per tonne in 2013/14 could result in R5,848 million (USD707 million) in carbon costs for 58 analyzed companies. The Basic Resources, Oil & Gas, Construction & Materials, Chemicals, and Food & Beverage sectors are the most exposed, with some companies facing annual operational carbon costs exceeding R50 million.
• Water scarcity presents a material financial risk, with the external value of water used by JSE top 100 companies estimated at over ZAR56 billion (USD6.8 billion) per annum, while they currently pay less than 1% of this true value (R224 million). The Food & Beverage sector is identified as 11 times more water-intensive than the next most intensive sector.
• The Government Employees Pension Fund (GEPF) has material exposure to carbon and water risks. While its carbon footprint is 9% smaller and its water footprint 6% smaller than the FTSE/JSE top 100, its R541 billion portfolio remains exposed, particularly through the Basic Resources sector.
• Institutional investors generally agree that South Africa's high-carbon infrastructure and lack of low-carbon incentives mean that market corrections for climate risks may occur too rapidly for an orderly portfolio adjustment, potentially leading to financial instability.
