Natural gas supply is reported by Local Distribution Companies (LDCs) and natural gas liquids (NGL) fractionators.</p>

<p><strong>NGL Fractionators</strong> are installations that receive natural gas or natural gas liquids from producers and fractionate these raw inputs into individual products (ethane, propane, normal butane, isobutane, or pentanes plus) and supply those products into the economy.</p>

<p><strong>Local Distribution Companies</strong> receive natural gas from a transmission pipeline company and physically deliver the gas to end users.</p>

<p>These Suppliers do not report direct emissions, but instead report the quantity of CO<sub>2</sub> that would be emitted if the fuels they supply each year were combusted. Emissions associated with these fuels do not occur at the supplier's facility but instead occur throughout the country, wherever they are used. The full GHG quantity reported by suppliers might not always result in GHG emissions, and the emissions might not take place during that particular reporting year. An example is ethane supplied by NGL fractionators, which is often used to produce plastics.</p>

<p>The GHG quantities reported by suppliers can be accessed through the <a href="http://ghgdata.epa.gov/ghgp/main.do#/facility/?q=Find a Facility or Location&amp;fid=&amp;sc=0&amp;so=0&amp;ds=S">suppliers section</a> of FLIGHT. Some natural gas and natural gas liquids suppliers also report direct emissions from petroleum and natural gas operations. <a href="/ghgreporting/ghgrp-petroleum-and-natural-gas-systems">Click here</a> to learn more.</p>

			<p>** Excludes CO<sub>2</sub> reported by NGL Fractionators whose reported quantities are classified as confidential business information (CBI). Among suppliers of natural gas liquids, the default emission factors used in 2013 and later years for propane, butane and isobutane increased by a few percent over those used in 2012 and prior years due to technical corrections to the reporting requirements. The default emission factor for ethane meanwhile decreased by over 30%. As a result of these changes, NGL fractionators reported a lower CO<sub>2</sub> value in 2013 and subsequent years than would have been reported if the factors had not been updated. The default emission factor for natural gas supplied for 2013 also decreased by about 1%. As a result of this change, LDCs reported a lower CO<sub>2</sub> value in 2013 and subsequent years than would have been reported if the factor had not been updated.</p>
