State CO2 Emissions from Fossil Fuel Combustion

In March 2022, US EPA began publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks by State to provide state-by-state emission and sinks consistent with the national greenhouse gas inventory, and with international standards.

The new data available in this report replaces the State CO₂ Emissions from Fossil Fuel Combustion data which were previously updated annually on this webpage.

The data provided below will not be updated going forward; please visit the Inventory of U.S. Greenhouse Gas Emissions and Sinks by State for annually updated information.

This section provides state carbon dioxide (CO₂) emission inventories from fossil fuel combustion, by end-use sector (commercial, industrial, residential, transportation, and electric power), in million metric tons of carbon dioxide (MMTCO₂) from 1990 through 2018.

EPA developed these state-level CO₂ estimates using (1) fuel consumption data from the DOE/EIA State Energy Data 2018 Consumption tables¹ and (2) emission factors from the Inventory of U.S. Greenhouse Gas Emissions and Sinks 1990-2018.

¹ SEDS sources motor gasoline estimates from the Federal Highway Administration (FHWA). FHWA has revised its methods of estimating non-highway use of motor gasoline for year 2015 and 2016 data, affecting how these data are allocated to each sector. While this revised methodology does not affect total petroleum consumed within SEDS, it does present compatibility issues with comparing 2015 and 2016 sectoral data across the time-series. EPA will update the time-series data to be consistent with future revisions of SEDS and other relevant sources such as the U.S. national greenhouse gas inventory as updates become available which address this issue.
