Better Health for All

The provided articles detail Ameren's initiatives to reduce carbon and SO₂ emissions

, acquire renewable energy facilities (solar, wind) , and set net-zero carbon goals . These actions are described as indirectly supporting public health through cleaner air .

and $67 million in another (2024-2026), to help customers save on electricity costs.
