State Emission Totals and Infographics
The annual Oklahoma Point Source Emissions Inventory is a data resource that utilizes emissions data to evaluate emission trends, support air dispersion modeling, aids in development of air quality rules, and air toxics risk assessment.
The National Emissions Inventory (NEI) is a comprehensive and detailed estimate of air emissions of Emissions Inventory System (EIS) first to collect the data from State, Local, and Tribal air agencies and then to blend that data with other data sources. More information can be found: https://www.epa.gov/air-emissions-inventories/national-emissions-inventory-nei, criteria precursors, and hazardous air pollutants from air emissions sources. The NEI is released every three years based primarily upon data provided by State, Local, and Tribal air agencies for sources in their jurisdictions and supplemented by data developed by the US EPA.

Summaries of annual emissions from all Oklahoma permitted facilities are available to be downloaded as excel spreadsheets. These reports are provided as a basic informational resource for the general public.
