Duke Energy Named to List of Best Corporate Citizens

CHARLOTTE, N.C. - Duke Energy has been named one of Corporate Responsibility Officer (CRO) magazine’s 100 Best Corporate Citizens.

The company earned this distinction based on CRO’s independent assessment of Duke Energy’s performance in seven key areas: environment, climate change, human rights, philanthropy, employee relations, financial and governance. CRO’s 2009 list of leading corporate citizens was released on March 6.

“Becoming a more sustainable business is a journey, not a destination. We’re pleased that our efforts earned us a spot on the list and to find ourselves in the company of other leading corporations,” said Roberta Bowman, Duke Energy senior vice president and chief sustainability officer. “Doing business in a way that’s good for people, the planet and profits is becoming increasingly important – especially during these turbulent times.”
