* U.S. energy-related CO2 emissions decreased 2.8% (150 million metric tons) in 2019 and were close to 2017 levels.
* Energy‐related CO2 emissions in the United States decreased by 2.8% (150 million metric tons [MMmt]) from 5,281 MMmt in 2018 to 5,130 MMmt in 2019 (Figure 2).
* The overall carbon intensity (CO2/GDP) of the U.S. economy declined 4.9% in 2019. This decline resulted from a 3.0% decrease in energy intensity and a 2.0% decline in the carbon intensity (CO2/energy) of the energy consumed.
* Since 2007 energy-related CO2 emissions have declined eight out of 12 years.
* As indicated in Figure 1 and the related discussion, after the economic recovery from the recession, energy-related CO2 emissions began to diverge from population growth, and on average they began to decline. The year 2019 was typical of the declining years that average about -3.0%.
