Abstract Methane fugitive emissions represent a critical challenge for the oil and gas industry, with implications for safety, environmental sustainability, and regulatory compliance. This paper presents a novel, scalable solution for continuous, source-level monitoring and quantification of methane leaks, aligned with emerging frameworks such as OGMP 2.0. The system consists of autonomous sensor nodes deployed directly on potential emission points within plant infrastructure. Each node integrates a methane-sensitive NDIR sensor, environmental probes, LoRa connectivity, and photovoltaic energy supply, housed in an ATEX Zone 0-certified enclosure. Three pilot campaigns—two in onshore facilities and one offshore—have demonstrated detection sensitivity below 1 gram per hour, confirming the system's reliability and robustness. All observed emissions, ranging from 1 to 100 g/h, were validated via conventional LDAR techniques. Data is wirelessly transmitted to a gateway and visualized through a cloud dashboard for post-processing and maintenance planning. This architecture supports digital transformation in emissions management by enabling persistent, low-impact monitoring with minimal manual intervention, contributing to Net Zero targets and operational excellence.
