"We strive for our customers, especially the underserved and vulnerable, to benefit from our efforts to increase clean energy generation and are supported to grow sustainable communities," Mizell said. "As chief sustainability officer, I will continue to ensure Ameren's environmental stewardship, positive social impact, robust corporate governance and ongoing sustainable growth initiatives are integrated in the company's strategy to realize our vision – Leading the way to a sustainable energy future."

"In the more than 500 communities Ameren Missouri serves, there is so much additional potential to grow opportunities and reduce energy burdens," Smith said.

And, thanks to the best economic development rates in the state, we're also helping companies expand and bringing new businesses to Missouri."

In addition, she completed certificate programs at the Harvard JFK School of Government as well as Georgetown University.

"We know that to deliver a sustainable energy future, we need to deeply commit to helping address the matters impacting our society, just as we do with those related to the environment," said Mark Fronmuller, senior vice president of strategy, innovation, sustainability and risk at Ameren. "Gwen's leadership in these areas has taken Ameren to the next level as she brings together people inside and outside the company to make a positive difference in our communities and our customers' lives."
