Emission Reduction Options for the Onshore Natural Gas Transmission and Underground Storage Segment
The EPA estimates methane emissions from the oil and natural gas industry in its annual Inventory of U.S. Greenhouse Gas Emissions and Sinks. The onshore natural gas transmission and underground storage segment contributes 25% to the total methane emissions from the oil and natural gas industry. The chart on the right shows the distribution of the top emission sources* in this segment, which represent 76% of the total emissions from natural gas transmission and underground storage. Click on each emission source category to view one of many appropriate, cost-effective methane mitigation options below. A full list of emission mitigation options can be found here.
“Other” Emission Sources: Pneumatic Devices, Uncombusted Methane, Centrifugal Compressors with Dry Seals, Dehydrator Vents
