The National Carbon Sequestration Database and Geographic Information System (NATCARB) Sources spatial database of stationary sources of atmospheric carbon dioxide (CO2) emissions across the USA and parts of Canada. Sources are classified into nine categories - Agricultural Processing Facilities, Cement and Lime Plants, Electric Generating Plants, Ethanol Production Plants, Fertilizer Production, Industrial Facilities, Petroleum or Natural Gas Transmission, Refineries and Chemical Facilities, and Unclassified. This data layer reflects the best available knowledge regarding stationary CO2 emissions sources in the USA and Canada. Version Log: v1101 - Initial release for Atlas III; v1103 - CANADA and WESTCARB data updated. Many duplicates among partnerships removed. Metadata revised; v1104 - Ethylene and Ethylene Oxide plants reclassified to Refineries/Chemical Plant; v1204 - Initial release for Atlas IV. New data submitted by all regional partnerships;v1302 - Locations reviewed and corrected for all electric power plants in MGSC, MRCSP and SECARB and some power plants in BSCP and SWP. Metadata revised.v1303 - Locations reviewed and corrected for all electric power plants in SWP and WESTCARB, and for all refineries in MGSC, MRCSP, SECARB, SWP, WESTCARB and parts of BSCSP. All PCOR sources replaced with most recent data from partnership. Fields DATA_SOURCE, COMMENTS, and RCSP_ID added to database schema. Metadata revised.The NATCARB is administered by the US Dept. of Energy (DOE) National Energy Technology Laboratory (NETL) and contains data provided by the Regional Carbon Sequestration Partnerships (RCSP). The NATCARB Team at KGS compiled the regional datasets into a single, seamless layer.
