In the following graphs, TXU’s emission rates for sulfur dioxide (SO2 ), nitrogen oxide (NOx)
and carbon dioxide (CO2 ) are compared with those of other owners of electric generating
facilities in the United States. The comparisons come from data in an independent report,
“Benchmarking Air Emissions of the 100 Largest Electric Generation Owners in the U.S. – 2000,”
prepared by the Natural Resources Defense Council (NRDC), the Coalition
for Environmentally Responsible Economies (CERES) and the Public Service Enterprise
Group (PSEG).

The data are from 2000 and are derived primarily from the U.S. Environmental Protection
Agency’s emissions reporting program, which collects hourly emissions data from over 900 power
plants based on Continuous Emissions Monitors. Information about power plant generation
is derived from data reported to the Energy Information Administration. The emission
comparisons presented here are made for fossil generating sources only so that zero– or
low-emitting sources, such as nuclear or renewable energy generating facilities, do not influence
the comparisons. The entire report can be found on the Internet at www.ceres.org.
