Ameren Part of Industry Initiative to Enhance ESG/Sustainability Reporting

Ameren Corporation is participating in a voluntary industry initiative, coordinated by the Edison Electric Institute (EEI), to provide electric industry investors with more uniform and consistent environmental, social, governance and sustainability-related (ESG/sustainability) metrics. The result of the initiative, EEI's ESG/sustainability template Version 1, will supplement Ameren's already substantial reporting on these issues, including its annual Corporate Social Responsibility report.

Ameren was a member of the steering committee that helped lead the EEI ESG/sustainability reporting effort. The template framework includes both qualitative information, including ESG/sustainability governance and strategy, and quantitative information, including data covering emissions, generation assets, portfolio data, and human and natural resources.
