Greenhouse gas (GHG) emissions are a major concern of environmental advocates and policymakers. Since methane is the primary component of natural gas, rising U.S. production from the rapid development of shale gas has caused an increased focus on methane emissions associated with natural gas production, transportation and consumption. One result of this increased attention is an evolution of research and analysis responding to general and specific inquiries regarding methane leakage from natural gas operations from the wellhead to the burner tip. Researchers have published several waves of papers on the topic since 2011.
This paper presents a literature review of primary papers issued in the past five years.
