• Greenhouse gas emissions (data for red trace in Version 1) was derived from other data provided in source.
• Source explains: "Indicator Notes. While this indicator includes the major greenhouse gases emitted by human activities, it does not include other greenhouse gases and substances that are not covered under the United Nations Framework Convention on Climate Change but that still affect the Earth’s energy balance and climate (see the Climate Forcing indicator for more details). For example, this indicator excludes ozone-depleting substances such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which have high global warming potentials, as these gases have been or are currently being phased out under an international agreement called the Montreal Protocol. This indicator also excludes black carbon and aerosols, which most greenhouse gas emissions inventories do not cover. While there are many natural greenhouse gas emissions sources, this indicator focuses on emissions that are associated with human activities—those that are most responsible for the observed buildup of these gases in our atmosphere. Although the land use, land-use change, and forestry emission estimates include emissions and sinks from unmanaged lands due to forest growth, fires, and other factors, this indicator does not include other natural sources such as methane emissions from unmanaged wetlands."
• Source states: "Data Sources. Data for this indicator came from EPA’s Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2020. This report is available online at: www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks. The calculations in Figure 3 are based on GDP and population data provided by the U.S. Bureau of Economic Analysis and the U.S. Census, respectively."
