Emission Reduction Options for the Natural Gas Distribution 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 natural gas distribution segment contributes 16% 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 97% of the total emissions from natural gas distribution. 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.

*Note: These emission estimates have an uncertainty associated with them. Not all facilities will have the same distribution of emissions between sources. Also, some emission sources are only present in a few facilities and may not be represented in the pie chart.

This pie chart breaks out three major emission sources from the Natural Gas Distribution segment.  The largest source of emissions is from Pipeline Leaks, which account for 47% of emissions.  Emissions from City Gates are second, accounting for 42%.  Customer Meter emissions rank third, making up 8%.  Other emission sources make up the remaining 3% of emissions.
