CO2 Stationary Sources

CO2 Stationary Source Emission Estimation Methodology

The NATCARB Viewer is available at:

DOE's Regional Carbon Sequestration Partnerships (RCSPs) employed CO2 emissions estimate methodologies based on the most readily available representative data for that particular industry type within the respective partnership area. CO2 emissions data provided by databases (for example, eGRID, IEA GHG, or NATCARB) were the first choice for all the RCSPs, both for identifying major CO2stationary sources and for providing reliable emission estimations. Databases are considered to contain reliable and accurate data obtained from direct emissions measurements via continuous emissions monitoring (CEM) systems. One drawback of formal databases can be the delay between data collection and publication, but this does not present a significant problem for the RCSPs as the dates of information are clear. When databases were not available, information was estimated from recently obtained information or garnered from various databases, websites, publications, mapping tools, and a variety of sources.  

All data, metadata, and high resolution .jpgs are available on NATCARB's Data Download and Custom Maps Request webpage.

CO2 emission sources are either stationary or non-stationary sources. CO2 stationary source emissions come from a particular, identifiable source, such as a power plant, while non-stationary source emissions include CO2 emissions from the transportation sector and other diffuse sources. CO2 emissions from stationary sources can be separated from stack gas emissions and subsequently transported to a geologic storage injection site. The United States and Canadian CO2 Stationary Sources map displays the location and relative magnitude of a variety of COstationary sources.

According to the U.S. Environmental Protection Agency (EPA), total U.S. greenhouse gas (GHG) emissions were estimated at 6,960 million metric tons (7,670 million tons) CO2 equivalent in 2008. This estimate includes CO2 emissions, as well as other GHGs, such as methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Annual GHG emissions from fossil fuel combustion, primarily CO2, were estimated at 5,570 million metric tons (6,140 million tons) with 3,780 million metric tons (4,170 million tons) from stationary sources.

The "CO2 Stationary Source Emissions by Category" pie chart contains values gathered by the RCSPs and NATCARB (illustrated on the United States and Canadian CO2 Stationary Sources map), showing that CO2 stationary source emissions result largely from power generation, energy use, and industrial processes.

While not all potential GHG sources have been examined, NETL’s RCSPs have documented the location of 4,507 CO2 stationary sources with total annual emissions of 3,470 million metric tons (3,825 million tons) of CO2 in the United States. In Canada, the locations of CO2 stationary sources with total annual emissions of 350 million metric tons (385 million tons) of CO2 were also identified. The CO2Stationary Source Emissions by RCSP and Canada pie chart displays the amount of CO2 stationary source emissions identified by each RCSP.
