This annual report provides a comprehensive accounting of total greenhouse
gas emissions for all man-made sources in the United States. The gases covered
by the Inventory include carbon dioxide, methane, nitrous oxide,
hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen
trifluoride.
In 2018, U.S. greenhouse gas emissions totaled 6,677 million metric tons
of carbon dioxide equivalents, or 5,903 million metric tons of carbon
dioxide equivalents after accounting for sequestration from the land sector.

printEmissions increased from 2017 to 2018 by 3.1 percent (after
accounting for sequestration from the land sector). This increase was
largely driven by an increase in emissions from fossil fuel combustion,
which was a result of multiple factors, including more electricity use greater
due to greater heating and cooling needs due to a colder winter and hotter
summer in 2018 in comparison to 2017.
Greenhouse gas emissions in 2018 (after accounting for sequestration
from the land sector) were 10.2 percent below 2005 levels.
