Private Equity, Public Harm

The Private Equity Climate Risks project has released a detailed report examining the public health externalities of private equity-backed fossil fuel infrastructure across the United States. The analysis quantifies previously untracked costs associated with air pollution from these assets, estimating total annual health damages between $11.3 billion and $15.1 billion—a figure that encompasses both direct health outcomes and their associated economic costs.

The research focuses on four categories of non-greenhouse gas pollutants: sulfur dioxide (SO₂), nitrogen oxides (NOₓ), volatile organic compounds (VOCs), and fine particulate matter (PM2.5). These compounds are established contributors to serious chronic and acute health conditions. Exposure pathways include cardiovascular disease, respiratory illnesses such as asthma and lung cancer, acute cardiac events including heart attacks and strokes, and emerging evidence linking air pollution to neurodegenerative conditions including Alzheimer's and Parkinson's disease. The modeling quantifies concrete impacts, attributing approximately 1,500 emergency room visits annually to air pollution from the selected private equity-backed facilities examined.

A core finding of the report is the opacity surrounding private equity's environmental and health footprint. Unlike publicly traded firms and regulated investment vehicles, private equity firms controlling substantial energy infrastructure remain largely exempt from comprehensive financial disclosure requirements. This regulatory gap obscures the true extent of third-party harms—costs borne by public health systems, affected communities, and healthcare consumers rather than by investors or operators. The analysis employed the U.S. Environmental Protection Agency's CO-Benefits Risk Assessment Health Impacts Screening and Mapping Tool (COBRA) to model impacts at the national level, by individual firm, and within two detailed regional case studies.

This report extends prior analysis from the 2024 Private Equity Climate Risks Scorecard, broadening the scope from greenhouse gas emissions to include non-GHG air pollution impacts. The findings underscore a structural misalignment: private equity's short-term value-extraction model generates quantifiable health and environmental liabilities that remain unpriced in investment decisions and unregulated through disclosure frameworks. For institutional investors and asset allocators, the data presents a material risk assessment challenge—the full cost of portfolio exposure to private equity-backed energy infrastructure extends significantly beyond climate metrics into documented public health harm.
