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.
