Chart shows total US greenhouse gas (GHG) emissions, by type, for the 1990-2019 period; without Land Use, Land-Use Change, and Forestry (LULUCF) emissions and sinks.
Total gross US GHG emissions were about 6,500 MtCO2eq in 1990 and steadily grew over 17 years until they peaked in 2007 at almost 7,500 MtCO2eq, 15.6 percent above 1990 levels. US emissions have since declined more dramatically over the past 12 years and, in 2019, stand only 1.8 percent above 1990 levels.
