U.S. Greenhouse Gas Emissions & Power Plants, 2010-2025

Clean, typed Parquet tables built from U.S. government spreadsheets:

• EPA Greenhouse Gas Reporting Program (GHGRP): the 2023 Data Summary Spreadsheets (2010-2023): emissions from about 7,500 large facilities and systems, by gas and process; fuel suppliers; CO2 storage.
• EPA GHGRP parent company data: who owns each facility, with ownership shares (2010-2023).
• EPA GHGRP-ORIS crosswalk and EPA/EIA power sector crosswalk: link GHGRP facilities to power plants and generators.
• EIA Form 923 (Power Plant Operations Report), 2010-2025: electricity generation and fuel use by every U.S. plant of 1 MW or more, fuel deliveries and costs, stocks, and environmental data (cooling water, coal ash, pollution controls).

These are the tables behind the U.S. Emissions Explorer dashboards. Every column is documented in the Malloy semantic model that ships with the project (models/*.malloy, #(doc) tags).

Tables (parquet/)

Table	Rows	One row per
emissions	108k	facility x year x reporting category (main GHGRP fact table, metric tons CO2e)
emissions_by_gas	278k	emissions report x gas
emissions_by_process	144k	point-source report x process (sums exactly to the total; includes an "Unallocated" remainder)
emissions_sectors, emissions_subparts	119k / 169k	report x listed sector / EPA subpart (membership bridges; do not sum through them)
facilities	11k	GHGRP facility (latest name, location, NAICS, sectors, FRS ID)
subparts	56	EPA subpart code lookup
supplier_quantities	12k	supplier x year x product (CO2e embodied in fuel supplied; not emissions)
co2_injection	1k	facility x year x CO2 injected / sequestered
parent_companies	130k	facility x year x parent company (ownership_share sums to 1; attributed_co2e = emissions x share)
facility_map	107k	facility x year, map-ready: location, industry, emissions, rank, change since 2011, owners, power stats
ghgrp_oris_crosswalk	2k	GHGRP facility x ORIS (power plant) code
power_generators / power_plants	5.8k / 1.7k	fossil generator / plant: capacity (MW), fuel, technology, status, retirement year
power_facility_year	23k	GHGRP power facility x year: EIA generation vs GHGRP emissions, tons CO2e per MWh
eia923_generation_fuel (+ _monthly)	223k / 2.1M	plant x year x prime mover x fuel: net generation (MWh) and fuel burned (MMBtu)
eia923_energy_storage	6k	storage plant x year
eia923_generator_generation (+ _monthly)	59k / 572k	generator x year
eia923_boiler_fuel (+ _monthly)	143k / 948k	boiler x fuel x year, with sulfur and ash content
eia923_fuel_receipts	635k	fuel delivery record: quantity, quality, supplier, coal mine, delivered cost
eia923_plant_stocks_monthly, eia923_stocks_by_region_monthly	249k / 35k	fuel stockpiles
eia923_plant_frame, eia923_plants	145k / 16k	plants expected to report / plant lookup
eia923_nonutility_disposition	100k	non-utility plant electricity sources and uses
eia923_byproduct_disposition	109k	coal ash and scrubber byproducts (thousand tons)
eia923_environmental_finance, eia923_fgd_operations	10k / 12k	pollution-control spending, scrubber costs
eia923_emissions_control, eia923_boiler_nox_operations, eia923_fgp_operations	94k / 6k / 4k	pollution-control equipment operation
eia923_cooling_monthly	256k	cooling water withdrawal, consumption and temperatures

Things to know

• Units: GHGRP values are metric tons of CO2-equivalent using IPCC AR4 global warming potentials. Biogenic CO2 is reported separately and is not in totals.
• Supplier quantities are not emissions. Never add them to the emissions totals; that would double count.
• 2010 GHGRP coverage is narrower. Start trends at 2011.
• Gaps filled from the multi-year workbook. The 2018-2022 annual GHGRP workbooks in EPA's zip contain no oil & gas, utility, SF6 or supplier rows. Those years come from the multi-year workbook (totals only; has_gas_detail = false).
• EIA markers. W (withheld) and . (not applicable) are nulls; *_withheld flags mark withheld values.
• Emissions per MWh. power_facility_year.tons_co2e_per_mwh divides by fuel-burning generation only, so co-located nuclear or hydro units don't dilute it.
• One flagged row. eia923_byproduct_disposition.is_implausible flags a single unit-entry error (plant 641, 2022).
