Exploring private equity's role in stopping methane leaks

In this episode of the All Things Sustainable podcast, we continue our deep dive into methane emissions. Today we’re exploring the role that private equity can play in eliminating methane emissions, including at abandoned oil and gas wells. 

Methane is the second largest contributor to global warming behind carbon dioxide. And the fossil fuel sector is responsible for nearly one-third of methane emissions from human activity today. Record production of oil, gas and coal, combined with limited mitigation efforts, has kept emissions above 120 million metric tons annually, according to the International Energy Agency’s 2025 Global Methane Tracker published in May. The IEA calls methane abatement a “crucial opportunity” to reduce near-term global warming. 

To understand how some companies are tackling methane emissions at abandoned facilities, in the episode we talk with Zefiro Methane Corp., an environmental services company that specializes in methane abatement at abandoned oil and gas wells in the US.
