The following represent particular space/time snapshots of the Vulcan inventory. They are presented as a checkpoint for using our data and to provide quick views of the Vulcan inventory. Full resolution images can be acquired by clicking the images.
The image above shows the location and magnitude of CO2 emissions from major power producers under the Continuous Emissions Monitoring program of the Emissions Trading System. Units: Million tonnes of carbon/facility/year
The image above shows the location and magnitude of the industrial point sources of CO2 emissions derived from the National Emissions Inventory. Units: Log base 10 of million tonnes of carbon/facility/year
The image above shows the location and magnitude of the mobile CO2 emissions as generated by the EPA mobile6 emissions model. Units: log base 10 of million tonnes of carbon/kilometer/year
The image above shows the complete Vulcan CO2 emissions (all sectors - those presented in the first three figures above plus residential, commercial, and cement) after it has been gridded to the common 10 km x 10 km Vulcan grid. The units are log base 10 of metric tonnes of carbon/gridcell/year. Given the dimensions of our common grid, this is a spatial area of 100 km2. This is a factor of 100x more resolved than previous work.
Total US fossil fuel CO2 emissions for 2002 come to 1506 million metric tonnes of carbon/year. This is slightly lower than Energy Information Estimates (1580 MtC/year) due to the missing nonroad and aircraft emissions in the Vulcan inventory (they are coming soon!).
