Update: Correction to Energy-Related CO2 Emission Data Tables
We discovered that for the years 2017 and 2018, the state energy-related carbon dioxide (CO2) emissions data series omitted distillate fuel inputs to the electric power sector. This had very little effect on total emissions in most states. However, in states such as Hawaii, the impact was relatively large given the percentage of electricity generated with petroleum. We have replaced that data set with the correct values.

The term energy-related CO2 emissions, as used in these tables, refers to emissions released at the location where fossil fuels are consumed.
Energy-related carbon dioxide (CO2) emissions vary significantly across states, on both an absolute basis and on a per capita basis.
Total state CO2 emissions include CO2 emissions from direct fuel use across all sectors, including residential, commercial, industrial, and transportation, as well as primary fuels consumed for electricity generation.

The underlying energy data used to calculate the state-level CO2 values can be found in the State Energy Data System (SEDS). SEDS is the main repository for all of EIA’s state-based energy data.
State Energy Portal offers multiple ways to examine energy and energy-related CO2 emissions data and contains narratives and rankings for each state.
EIA Energy Mapping System is an interactive map that shows the major energy facilities and infrastructure in the United States.
EIA collects data on state emissions for the electric power industry for sulfur dioxide and nitrogen oxides as well as CO2. The electric power industry includes electricity generated in the electric power, industrial, and commercial sectors. The downloadable spreadsheet includes U. S. electric power industry estimated emissions by state from 1990 (Form EIA-860 and Form EIA-923).
State Emissions Data API offers programmatic ways to examine energy and energy-related CO2 emissions data.
