Notes

In 2023, the United States emitted nearly 6.2 billion metric tons of greenhouse gases (CO2e). Carbon dioxide accounted for the largest percentage of greenhouse gases (79%), followed by methane (11%), nitrous oxide (6%), and other greenhouse gases (3%).

Greenhouse gases are emitted by all sectors of the economy, including transportation (30% of total), electric power (24%), industry (23%), residential and commercial (13%), and agriculture (10%).

Notes

Emissions from energy consumption fell by a bit less than one half of a percent in 2024 as declines in natural gas and coal use were offset somewhat by a rise in petroleum use.

Notes

Energy-related carbon dioxide emissions have fallen by more than 20 percent since 2005 due to lower coal and petroleum consumption and an increasing share of renewable electricity. This has been offset somewhat by an increasing share of natural gas consumption.

Notes

Natural gas, which emits about half the amount of CO2 as coal, is being used more extensively due to its lower price and is displacing coal-fired generation.

Power sector emissions rose slightly in 2024 as coal and petroleum declines were offset by a rise in natural gas-fired generation. Power sector carbon dioxide emissions are down nearly 41 percent from 2005 levels.
