EIA has published the March 2023 Monthly Energy Review, with its first, preliminary data for calendar year 2022. Today, let's look at U.S. CO2 emissions.
First estimates for 2022 CO2 emissions are 4,969.9 million metric tons (MMT). This is 1.37% higher than the 2021 total, though still over a billion tons lower than the U.S. peak CO2 peak years 2005-2007. The electric power sector showed a slight decline from 2021, while all other sectors (the non-electric portions) showed increases of 1.5% to 5.0%.
We can also look at the relative contributions of each consuming sector to the overall longer-term changes in CO2 emissions. As seen in the chart below, by far, most of the drop in CO2 emissions since 2005 has been in the electric power sector, now down over 35% from 2005 levels. In the transportation sector, the steep declines seen early in the pandemic are now being reversed as transport-related activity continues to pick up.
