KEY: N = data do not exist; R = revised.
a Fine particulate matter less than 10 microns.
b Other off-road comprises nonroad gasoline- and
diesel-powered recreational, airport service and railway maintenance
vehicles, and recreational marine vessels.
c Industrial processes comprises chemical and allied product
manufacturing, metals processing, petroleum and related industries, and other
industrial processes; solvent utilization; and storage and transport.
d Miscellaneous comprises nonroad gasoline- and diesel-powered
construction, industrial, lawn and garden, farm, light-commercial, logging
vehicles and other non-road sources; geogenic sources; agriculture and
forestry, cooling towers, nontransportation-related fugitive dust, wildfires,
managed burning, and other combustion sources that could not be accurately
allocated to specific source categories.
NOTES
The
methodologies used to estimate emissions constantly evolve and undergo major
changes. These improved methods are
often used to revise estimates for previous years and, therefore, some
estimates in this table may not match estimates produced in previous
reports.
Numbers may not add to totals due to rounding.
