Here’s some interesting news about visualization for point source air pollution from the Environmental Protection Agency. The Atlanta region is a federally designated nonattainment area for certain forms of air pollution. As such, ARC tracks mobile source emissions (as estimated from the implementation of the Regional Transportation Plan) in order to meet requirements set forth in the Clean Air Act. Visit ARC’s air quality page for more information about the various types of air pollution and regional air quality planning efforts.
WASHINGTON – For the first time, comprehensive greenhouse gas (GHG) data reported directly from large facilities and suppliers across the country are now easily accessible to the public through EPA’s GHG Reporting Program. The 2010 GHG data released today includes public information from facilities in nine industry groups that directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels.
“Thanks to strong collaboration and feedback from industry, states and other organizations, today we have a transparent, powerful data resource available to the public,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “The GHG Reporting Program data provides a critical tool for businesses and other innovators to find cost- and fuel-saving efficiencies that reduce greenhouse gas emissions, and foster technologies to protect public health and the environment.”
EPA’s online data publication tool allows users to view and sort GHG data for calendar year 2010 from over 6,700 facilities in a variety of ways—including by facility, location, industrial sector, and the type of GHG emitted. This information can be used by communities to identify nearby sources of GHGs, help businesses compare and track emissions, and provide information to state and local governments.
GHG data for direct emitters show that in 2010:
•Power plants were the largest stationary sources of direct emissions with 2,324 million metric tons of carbon dioxide equivalent (mmtCO2e), followed by petroleum refineries with emissions of 183 mmtCO2e.
•CO2 accounted for the largest share of direct GHG emissions with 95 percent, followed by methane with 4 percent, and nitrous oxide and fluorinated gases accounting for the remaining 1 percent.
•100 facilities each reported emissions over 7 mmtCO2e, including 96 power plants, two iron and steel mills and two refineries.
Mandated by the FY2008 Consolidated Appropriations Act, EPA launched the GHG Reporting Program in October 2009, requiring the reporting of GHG data from large emission sources across a range of industry sectors, as well as suppliers of products that would emit GHGs if released or combusted. Most reporting entities submitted data for calendar year 2010. However, an additional 12 source categories will begin reporting their 2011 GHG data this year.
