TITLE:
"Air Quality Impacts of Expanded Natural Gas Production and Use"


ABSTRACT:
Air pollutant emissions from the natural gas supply chain are a key factor in determining the environmental footprint of natural gas production and use. Recent estimates of emissions, particularly for methane, a potent greenhouse gas, have varied widely. The variation is due to the large population of sources, different measurement and estimation approaches, and extreme values of emission rates from individual sources that are much larger than population average values of emission rates from sources in the same category (a “fat-tail” distribution). Reconciling differences between ambient concentration measurements (top-down methods) and direct measurement of emissions from individual sources (bottom-up methods) is critical to understanding methane and other emissions from the natural gas supply chain. This presentation will review and attempt to reconcile selected recent bottom-up and top-down measurements.
