ESG Performance Data

A common phrase in sustainability is that you can’t manage what you don’t measure. At Ameren, we collect and use our environmental, social and governance (ESG) performance data to measure our progress, identify any issues and set targets for continuous improvement. We also report that ESG performance data on a regular basis to inform our stakeholders how we are tracking on our sustainability commitments.

Ameren uses a number of tools, audits and processes, including an Environmental Management System, to enable us to monitor and analyze the impact of our operations. This data helps us make strategic decisions for the future. For example, Ameren is investing in the energy grid through modernization and resilience efforts and transitioning to net-zero emissions and a clean energy portfolio by 2050. Closely tracking our environmental performance will help ensure we make timely progress toward each milestone of this goal. Similarly, analyzing our performance in areas like diversity, equity and inclusion, safety and community investment holds us accountable to continue to do what’s right for our employees and communities.
