The NATCARB Viewer allows users to browse and query data under Regional Carbon Sequestration Partnership (RCSP), Atlas V, Worldwide CCS Database, Brine Well Samples, and other tabs. The number of stationary CO2 sources, CO2 emissions, and CO2 storage resource estimates reported in Atlas V is based on information gathered by the National Carbon Sequestration Database and Geographic Information System (NATCARB). NATCARB is a relational database and geographic information system (GIS) that integrates CCS data from the RCSPs and other sources. NATCARB provides a national view of the carbon storage potential; data from NATCARB is uploaded into Energy Data eXchange (EDX).
