Residential natural gas meter set assemblies (MSAs) emit methane (CH), but reported emissions factors vary. To test existing emissions factors, we quantified CH emissions from 37 residential MSAs in Calgary, Alberta, Canada. A notable difference with previous studies is the targeted measurement of regulator vents in this study, which were measured with a static chamber, while fugitives were measured with a modified hi-flow sampler.

The occurrence and emissions of methane (CH) from above-ground urban natural gas infrastructure is poorly understood. Compared to below-ground infrastructure, these facilities are relatively easy to monitor and maintain and present an opportunity for cost-effective CH reductions. We present a case study and methodology for detecting, attributing, and quantifying CH emissions from fence line measurements at above-ground natural gas facilities in the City of Calgary, Alberta, Canada.
