Summary

Suppliers of carbon dioxide (CO2) consist of the following: 

  • Facilities with production process units that capture and supply CO2 for commercial applications that capture and maintain custody of a CO2 stream to sequester or otherwise inject it underground. 

  • Facilities with CO2 production wells. 

  • Importers of bulk CO2, if total combined imports of CO2 and other greenhouse gases (GHGs) exceed 25,000 metric tons of CO2 equivalent per year (tonnes CO2e/year). 

  • Exporters of bulk CO2, if total combined exports of CO2 and other GHGs exceed 25,000 tonnes CO2e/year. 

This source category does not include entities that store CO2 through geologic sequestration (GS) or above ground storage; use CO2 in enhanced oil and gas recovery; transport or distribute CO2; purify, compress, or process CO2; or import or export CO2 in equipment.
