Here's where energy-related CO2 emissions come from in the US

In 2021, energy-related CO2 emissions in the United States reached 4.9 billion tonnes, marking the largest annual increase on record. Transportation and electricity generation were the primary drivers, together accounting for over 68% of these emissions. Within these sectors, petroleum dominated transportation emissions, while coal and natural gas dominated electricity generation.

• U.S. energy-related CO2 emissions reached 4.9 billion tonnes in 2021, which represented the largest annual increase ever recorded, with an increase of 325 million tonnes following a decline in 2020.
• Transportation and electricity generation were the dominant sources of energy-related emissions in 2021, together contributing more than 68% of the total, or approximately 3.3 billion tonnes of CO2. Petroleum was responsible for 97% of transportation emissions, while coal and natural gas accounted for 99% of emissions from electricity generation.
• The carbon intensity of U.S. electricity increased by 4% in 2021. This was driven by an increase in the share of coal in the electricity mix, which rose from 20% to 23%, leading to the first increase in electricity emissions from coal since 2014.
