Analysis
The most recent figure for annual greenhouse gas emissions by world region in United States is 6.05 billion tonnes of CO₂ equivalents, measured in 2024.
Compared with earlier readings it is down 0.4% on the previous year and down 8.4% over ten years.
Over the whole period, annual greenhouse gas emissions by world region in United States peaked at 7.43 billion tonnes of CO₂ equivalents in 2005 and was at its lowest, 774.04 million tonnes of CO₂ equivalents, in 1850.
That places United States 2nd out of 199 countries with data for 2024, putting it in the top 10%.
The series is highly variable year to year, so single readings are best treated with caution.
