The Private Equity Firms Quietly Fueling Global Emissions

Twenty private equity giants are overseeing portfolios that generate 1.5 billion tonnes of greenhouse gases annually, a footprint eclipsing the emissions of every nation except China, the United States, India, and Russia. Despite public pledges toward decarbonization, these firms are tightening their grip on the world’s most carbon-intensive infrastructure.

The Private Equity Firms Quietly Fueling Global Emissions

The scale of this involvement is vast. An analysis by the Private Equity Climate Risks Consortium reveals that these firms control 15,000 miles of pipelines and 124 GW of power generation capacity across 370 fossil-fuel plants. While many institutions initially adopted environmental, social, and governance standards following the pandemic, a significant reversal is underway. Firms such as BlackRock, GIP, Energy Capital Partners, EQT, and Kayne Anderson have expanded their fossil fuel holdings throughout 2024 and 2025.

Financial data underscores this pivot. S&P Global reports that investment in oil and gas transportation—including pipelines and shipping—reached $4 billion in the first eight months of last year, outpacing previous cycles. The surge is partly tied to the energy-hungry AI boom. With private equity backing roughly half of the top 10 U.S. data center owners, these facilities are increasingly reliant on natural gas to power massive computing operations, effectively tethering the future of high-tech development to traditional carbon sources.

Contradicting the industry's long-standing defense that fossil fuel assets guarantee superior returns, the consortium’s study of 145 funds launched between 2001 and 2016 found a meager 1 percent return on $190.4 billion in capital. Matt Parr of the Private Equity Stakeholder Project notes that the sector operates with little transparency, complicating regulatory efforts to track how these investments keep aging fossil fuel projects commercially viable. Even firms branding themselves as climate-conscious, such as Sweden’s EQT, face scrutiny as they weigh acquisitions of companies like AES Corporation, where fossil fuels still account for half of the total generation capacity.
