GB/T 48149-2026 is the English-translated version of 陆上石油天然气工业甲烷排放监测技术指南.

Annexes describe specific techniques such as pan-tilt laser telemetry, portable instrument and high-flow sampling methods, and vehicle-mounted and drone-mounted detection.

They are meant to guide enterprises engaged in onshore oil or natural gas exploration, development and long-distance transportation in work such as emission supervision, emission factor development, leak detection and repair, and the accounting and verification of emissions and reductions.
