Summary

A new report by the Private Equity Climate Risks Consortium finds that 20 top private equity firms manage $7.3 trillion in assets, including energy portfolios responsible for emitting 1.5 billion tons of greenhouse gases annually—more than any country except China, the US, India, and Russia. These firms own extensive fossil fuel infrastructure such as pipelines, power plants, and oil fields, with some expanding investments in datacenter-related electricity production from coal and natural gas sources despite claims of supporting a transition to cleaner energy.

Story summary

The energy portfolios of 20 private equity firms emit 1.5 billion tons of greenhouse gases annually, surpassing the yearly emissions of any country except China, the US, India, and Russia, according to an analysis by the Private Equity Climate Risks Consortium. These firms manage a total of $7.3 trillion in assets across various sectors but are heavily involved in fossil fuel investments such as natural gas and coal-fired power plants that supply electricity to data centers. The consortium found that these firms control 15,000 miles of pipelines, 124 gigawatts of power generation capacity spanning 370 fossil fuel-powered plants, and numerous oil and gas fields worldwide. Matt Parr from the Private Equity Stakeholder Project, one of the organizations involved in the consortium, noted that this industry often receives insufficient attention for its significant contribution to global emissions due to its opaque nature.

While some public-sector retirement systems have been trying to limit their exposure to fossil fuel projects, the private equity firms BlackRock, GIP, Energy Capital Partners, EQT and Kayne Anderson increased the amount of fossil fuel companies in their portfolio compared with 2024, according to the report. uncertain
firms → try → report
The private equity firm EQT has positioned itself as a climate conscious investor, supporting the energy transition. asserted
