		<div class="accordion-pane" id="pane-1">
			<p>As directed by Congress, EPAâ€™s Greenhouse Gas Reporting Program (GHGRP) collects annual greenhouse gas information from the top emitting sectors of the U.S. economy (Table 1). The GHGRP is the only dataset containing facility-level greenhouse gas (GHG) emissions data from large industrial sources across the United States. With five years of reporting for most sectors, GHGRP data are providing important new information on industrial emissionsâ€”showing variation in emissions across facilities within an industry, variation in industrial emissions across geographic areas, and changes in emissions over time at the sector and facility level. EPA is using this facility-level data to improve estimates of national greenhouse gas emissions, including using it to improve the <a href="/ghgemissions/us-greenhouse-gas-inventory-report-1990-2014">U.S. Greenhouse Gas Inventory</a>. The data are also being used to inform regulatory actions and voluntary emission reduction efforts.</p>

			<p>This document summarizes national industrial sector emissions and trends.</p>

			<p><span style="vertical-align:baseline">1Â </span>The Southern California Gas Company - Aliso Canyon facilityâ€™s actual 2015 emissions were higher than those reported to the GHGRP. The GHGRP provides well-vetted average emission factors to calculate emissions. The facility followed these GHGRP calculation methods for 2015 reporting. Actual emissions differ from those reported due to an exceptional leak event.

			<p>The GHGRP does not represent total U.S. GHG emissions, but provides facility level data for large sources of direct emissions, thus representing the majority of U.S. GHG emissions. The GHGRP data collected from direct emitters representing about half of all U.S. emissions. When including greenhouse gas information reported to the GHGRP by suppliers, emissions coverage reaches approximately 85â€“90% (See Figure 1). The <a href="/ghgemissions/us-greenhouse-gas-inventory-report-1990-2014"><em>Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2014</em></a> contains information on all GHG emissions sources and sinks in the United States.</p>

			<p>Suppliers report the quantity of GHGs that would be emitted if the fuels and industrial GHGs that they place into the economy each year are used/released. Reporting by suppliers helps account for the greenhouse gas emissions by the numerous low-emitting sources that are not required to report emissions under the GHGRP (e.g., mobile sources, residential sources). <a href="/ghgreporting/ghgrp-supplier-highlights">Learn more about suppliers and their 2015 reported data</a>.</p>

The Greenhouse Gas Reporting Program is different from the U.S. GHG Inventory in that it collects information from the largest stationary sources in the U.S. and provides nearly complete emissions coverage for many of the largest emitting industries. Trends in emissions reported for individual industries are discussed in the industry-specific reports.</p>

			<p>Total U.S. emissions increased by 1.0% from 2013 to 2014, based on the U.S. GHG Inventory. Between 2013 and 2014, emissions reported to the GHGRP increased by 0.5% (Table 4).</p>

			<p>The U.S. GHG Inventory is not yet available for 2015. For sources reporting to the GHGRP, emissions increased by 0.5% from 2013 to 2014. Over the past five reporting years (2011-2015), GHGRP reported emissions have declined by 8.2%. This decline is caused primarily by a 11.3% decline in reported emissions by power plants since 2011.</p>

		<div class="accordion-pane" id="pane-7">
			<p>The GHGRP provides a comprehensive dataset that can be used to determine the number of facilities at various emissions levels in many industry sectors. The GHGRP can also be used to determine the total GHG emissions from individual facilities, including emissions from fossil fuel combustion and other processes. This information is valuable for planning future policies. GHGRP data provide policy makers with a better understanding of the number of facilities and total emissions that would be covered by potential GHG reduction policies for various industries.</p>

			<p>Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO<sub>2</sub>e. In 2015, the 651 largest-emitting facilitiesâ€”those emitting more than one million metric tons CO<sub>2</sub>eâ€”accounted for almost 2.2 billion metric tons CO<sub>2</sub>e. These emissions represent 71.7% of the total 3.05 billion metric tons CO<sub>2</sub>e reported. These high-emitting facilities are mainly power plants, but also include petroleum refineries and facilities in the Chemicals and Metals sectors.</p>

		<div class="accordion-pane" id="pane-8">
			<p>The GHGRP prescribes methodologies that must be used to determine GHG emissions from each source category. Reporters generally have the flexibility to choose among several methods to compute GHG emissions. The decision of which method to use may be influenced by the existing environmental monitoring systems in place and other factors. Reporters can change emission calculation methods from year to year and within the same year, as long as they meet the requirements for use of the method selected.</p>
