Natural Gas Emissions by Industry Segment (image) Stanford University Share Print E-Mail Caption Above: This shows EPA Greenhouse Gas Inventory leakage estimates. Below: This shows results from recent experimental studies. Studies either focus on specific industry segments, or use broad atmospheric data to estimate emissions from multiple segments or the entire industry. Studies have generally found either higher emissions than expected from EPA inventory methods, or found mixed results (some sources higher and others lower).
