Zefiro Methane supports Isometric's new orphaned well plugging protocol
Zefiro Methane Corp. has provided financial and technical support for Isometric's new Orphaned Well Plugging (OWP) Protocol, which is undergoing a 30-day public consultation until 14 November 2026. The draft protocol requires direct on-site methane leakage measurements before well sealing and projects reductions over a 20-year crediting period. It also mandates 12-to-18-month post-plugging permanence verifications and buffer-pool withholdings. Finalisation of this methodology will enable Zefiro to resume originating carbon credits from unscheduled orphaned wells, supplementing its core services which generated $42.5 million in fiscal 2026.
