Other examples include post-mitigation measurements of CH4 emissions following equipment replacement, upgrades, and facility rebuilds at city-gate and M&R stations across the U.S. . In three cases, aerial measurements led directly to mitigation of CH4 emissions from natural gas distribution pipelines and a liquified natural gas storage tank by notifying operators of the emissions . Last, partly attributed a declining regional-level trend in CH4 emissions in the Los Angeles Basin from 2015 to 2020 to leak detection and repair (LDAR) at O&G sites in the region; however, the exact sources mitigated are unclear based on the scale of measurement. Notably, mitigating CH4 emissions from combustion slip was not featured in the studies, but potential approaches could include appliance efficiency improvements, retrofits or replacements, and end-use fuel switching.
