• Industrial coatings—factory-applied to
manufactured goods during production.
• Special-purpose coatings—aerosol paints, marine
paints, high-performance coatings, and automotive
refinish paints.
• Allied paint products—putties, paint and varnish
removers, paint thinners, pigment dispersions, paint
brush cleaners, and frit (ground glass or glaze).
Energy Use
In 2002, the Paint & Coatings sector purchased about 1.6
billion kilowatt hours of electricity for heat and power,
which represented well under 1% of the total quantity
of electricity purchased for heat and power by U.S.
manufacturers. 4 Data on fossil fuel consumption are not
currently available.
Air Emissions
Air emissions from the sector include criteria air pollutants
(CAPs), greenhouse gases (GHGs), and a number of
chemicals reported to EPA’s Toxics Release Inventory (TRI).
In general, the “toxic chemicals” tracked by TRI are found
in the raw materials used as formulation ingredients in the
manufacturing process.
Air Emissions
Reported to TRI

2005, absolute TRI-reported air emissions declined by
about 57%, as shown in Figure 1a. When normalized by
