Cinergy Named Sustainability Leader for Third Straight Year

Cinergy Corp. (NYSE:CIN) has been named to the Dow Jones
World Sustainability Indexes, an international benchmark for
excellence in social, economic and environmental leadership, for the
third straight year.
   Cinergy is one of only two utility companies in the United States,
and eight in the world, to be named to the Indexes. The World Indexes
cover the top 10 percent of the 2,500 largest companies in the world,
providing asset managers with objective and reliable benchmarks to
manage sustainability portfolios.
   "Sustainability is a way of looking at our business through the
eyes of our children and grandchildren," said James E. Rogers,
chairman and chief executive officer of Cinergy. "I believe we make
better choices when we frame the business decisions we make today with
the question: How will those decisions be viewed by our grandchildren
a generation from now? Being recognized by Dow Jones as a leader in
corporate citizenship is gratifying and really speaks to the
dedication our employees have to their work and to the communities we
serve."
   Launched in 1999, the Dow Jones Sustainability Indexes are the
first global indexes that track the corporate citizenship performance
of the leading sustainability-driven companies worldwide. The Indexes'
detailed surveys provide a thorough assessment of general and
industry-specific sustainability criteria and are verified by an
external auditor.
   Cinergy provided extensive data about its business philosophy and
programs that are designed to promote economic growth in the
communities it serves, to meet social and environmental needs and to
provide a safe and attractive workplace for employees. The company's
Sustainability Annual Report is available on the Internet at
