Zefiro Methane completes first-ever sale of carbon offsets

Zefiro Methane Corp, a fully integrated environmental services company which originates institutional-grade carbon credits by remediating unplugged oil and gas wells in the United States, is pleased to announce both the successful issuance of certified carbon credits from American Carbon Registry Project 959 reflecting confirmed emissions reductions of 92,956 metric tonnes of CO2 equivalent, as well as completed delivery of the first tranche of ACR959 carbon credits to Mercuria Energy America, LLC.

This pair of events marks the debut of a third key revenue stream for Zefiro, supplementing its earnings from core operations which have already generated USD $24.4 million in revenue for the company’s first three fiscal quarters of 2025 (as announced in Zefiro’s May 14, 2025 press release).

In addition to Zefiro’s plugging and abandonment division in the Appalachia region (Pennsylvania, Ohio, New York, and West Virginia), Zefiro also recently announced its very first revenues from methane monitoring, with a USD $800,000 contract to provide services to the West Virginia Department of Environmental Protection.

In May of 2023, ACR published a first-of-its-kind methodology allowing carbon offsets to be created by plugging orphaned oil/gas wells. Under the leadership of Tina Reine, Zefiro’s Chief Commercial Officer who was one of the founding members of J.P. Morgan’s carbon trading desk, Zefiro began to undertake all of the necessary steps to originate some of the first-ever offsets to be created under the methodology.

This included taking preliminary methane emission measurements, completing all well-level plugging/remediation work, and engaging a third-party Validation and Verification body to independently certify all findings as announced in a press release earlier this year.

The ACR959 project is based on a well located on privately owned land in Custer County, Oklahoma. On June 21, 2025, post-plugging monitoring confirmed that the well was plugged and in compliance with ACR methodology. On July 29, 2025, validation was officially completed by the VVB.

As a result of the completion of ACR959, Zefiro was issued carbon offsets reflecting emissions reductions of 92,956 metric tonnes of CO2 equivalent.
