Facility Insight: Tyson Poultry Inc. Grannis Processing Plant

Tyson Poultry Inc. Grannis Processing Plant (EPA GHGRP Facility ID 1014852) reported 29K metric tons of CO2-equivalent in 2023, operating in Grannis, AR within POLK COUNTY. The site is classified under Other with NAICS code 311615, placing it within the group of U.S. facilities that cross the 25,000 MT CO2e annual reporting threshold set by EPA under 40 CFR Part 98. Self-reported emissions are verified by EPA staff, and the reported CO2e total aggregates CO2, methane (CH4), and nitrous oxide (N2O) weighted by their 100-year global warming potentials.

The facility has 1 year of reported data on record. Over that period, annual CO2e emissions cannot be trended without a multi-year baseline, with the peak observed year showing up to 29K MT CO2e. Because facility emissions can swing year-to-year based on production volume, fuel mix, outages, or control upgrades, a single year rarely tells the full story — the emissions history table above unpacks CO2, CH4, and N2O contributions separately so readers can see which gas is driving the trend.

For context, this reported total captures Scope 1 direct emissions from on-site combustion, industrial processes, and fugitive sources — it excludes Scope 2 purchased electricity and Scope 3 upstream or downstream emissions. Users comparing this facility to others in AR should cross-reference with the state-level rollup on our AR emissions page and the parent company profile where linked, since facility-level disclosures are most meaningful when placed against the operator's broader portfolio. All underlying data is EPA-published and freely available via the GHGRP envirofacts API.
