These data are an update to 2012-2020 Greenhouse Gas National- and State-Level Emission Totals by Industry (https://doi.org/10.23719/1529805). Data for 2021 and 2022 are added and are aligned with the 2012-2022 National-Level Greenhouse Gas Emission Totals by Industry (https://doi.org/10.23719/1531141). The Excel file contains a sheet with these totals by state and sector and year for each year in the time series along with metadata. Links are provided to the datasets in parquet format as generated by FLOWSA. Supporting metadata for each dataset is provided in the links.

The primary emissions source was updated to use the EPA "Inventory of U.S. Greenhouse Gas Emissions and Sinks by State" 2024 report. The industry classifications were updated to use 2017 North American Industry Classification Codes. The code used to generate the datasets is available in the FLOWSA v2.0.5 tool (https://github.com/USEPA/flowsa/tree/v2.0.5). Values are given in total kilograms emitted for the given year, sector and location. Please see the related publication for more background information. https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=360507&Lab=CESER

Validation: A supporting zip archive (GHG_by_Sector_and_State_2012-2022_validation.zip) is provided with results of various validation checks. Files with the pattern 'GHG_XXXX_rel_state_flow_comparison.csv' where 'XXXX' is the data year show totals by gas in a given year summed across states from this dataset ('state' field) compared to previously published national totals by gas produced from the national totals by industry ('national' field) for the same year. 'comp' is a ratio of 'state':'national'. All other fields are the same as those found in the FLOWSA flow-by-sector data format. Files with the pattern 'GHG_XXXX_rel_state_sector_comparison.csv' where 'XXXX' is the data year show the totals by gas by industry in a given year summed across states by gas and by industry compared to national totals by gas by industry by year. Fields have the same meaning as described above. Additional validation and log files of the associated FLOWSA model runs can be found on the EPA Data Commons (https://dmap-data-commons-ord.s3.amazonaws.com/index.html#flowsa/FlowBySector/) where the parquet and metadata files reside and have the same file names but end in .log and _validation.log. Please read more in the FLOWSA documentation to understand these files.
