The Data Explorer is an interactive tool that provides access to data from the EPA's annual Inventory of U.S. Greenhouse Gas Emissions and Sinks and the new Inventory of U.S. Greenhouse Gas Emissions and Sinks by State. You can use the tool to create customized graphs, examine trends over time, and download data. Visit other EPA pages to learn more about the EPA's national Inventory and how it relates to EPA's Greenhouse Gas Reporting Program and the EPA's state-level greenhouse gas (GHG) data. The EPA recognizes that there will be differences between the EPA's state-level GHG estimates and some inventory estimates developed independently by individual state governments. Inventory data presented here should not be viewed as official data of any state government. Additional information is available on official state GHG data, where it exists, including information on potential areas of difference between EPA's data and official state data.

Notes on viewing graphs:

• To view a graph, you can either pick from the full list in the Index of Charts or create a graph by choosing options from the six dropdown menus below.
• You must select all dropdown menus in sequential order to view a graph. A graph may remain visible until you sequentially select all six dropdowns to see a new graph. Some drop-down menu options are unavailable at this time and may be added in the future as more data and capabilities are added to the tool.
• Within each graph, you can click the legend to turn layers on or off, and you can hover your mouse over the display to reveal data. Graph data can be downloaded from the table below each graph.
• Values are rounded to the nearest thousandth. Values of 0.000 may represent positive values less than 0.0005 MMT CO2 Equivalent.
