EPA Greenhouse Gas Reporting (e-GGRT)
EPA_GHGRPfree10 data-quality rules for EPA Greenhouse Gas Reporting Program (GHGRP) submissions via e-GGRT under 40 CFR Part 98. Covers required facility identification and subparts, valid gas types and Global Warming Potentials, non-negative emissions, CO2e calculation consistency, reporting year, units, and duplicate suppression. Use it to validate the annual GHG report before e-GGRT submission.
Checks included (10)
GHGRP Facility ID Present(ghgrp_facility_id)
Each report must carry the EPA GHGRP facility identifier.
Required Subpart Fields Present
Each emissions record must identify its 40 CFR Part 98 subpart, the gas, and the emissions quantity.
Reporting Year Present(reporting_year)
The report must specify the reporting year (RY).
Subpart Is a Valid Part 98 Subpart
The reported subpart must be a valid 40 CFR Part 98 subpart code.
GWP Matches the Mandated Value
The Global Warming Potential used must match the value mandated in Table A-1 of Part 98 for the gas.
CO2e Equals Quantity Times GWP
Reported CO2-equivalent must equal the gas quantity multiplied by its Global Warming Potential (within rounding tolerance).
Facility Total Equals Sum of Subparts
The facility total CO2e must equal the sum of subpart-level CO2e (within rounding).
Gas Type Is Valid(gas_type)
Gas type must be a reported GHG (CO2, CH4, N2O, SF6, HFC, PFC, NF3).
Emissions Are Non-Negative(emissions_quantity)
Reported emissions quantities (metric tons) cannot be negative.
One Record per Facility / Subpart / Gas(emissions_dedup_key)
Emissions should be reported once per facility, subpart, and gas for the reporting year.
