Zefiro Methane Corp provides end-of-life solutions for industrial oil and gas operations that emit harmful greenhouse gas (GHG) emissions, specifically methane released from orphaned and abandoned oil and gas wells or associated midstream assets. It generates carbon credits, which can then be sold into carbon credit markets, by reducing methane emissions through the plugging of orphaned and abandoned oil and gas wells. Its services include methane testing, quantification, and monitoring, asset retirement and methane abatement, and carbon offset generation among others. It has a single segment, being the provider of a range of turnkey solutions to plug onshore oil and gas wells across the Appalachian Basin. It operates in the United States which generates all of its revenue, and Canada.
