Supply Chain Sustainability

Ameren’s suppliers and business partners play an important role in helping us create a more sustainable energy future. Our goal is to build a supply chain that supports Ameren’s sustainability priorities. This includes defining a strategy to integrate our supply chain platform with corporate Sustainability/ESG strategy and collaborating with suppliers and business partners to identify ways to operate more sustainably.

Essential to this approach is partnering with suppliers who are responsibly managing the environmental, social and economic impacts of their business. We do this by ensuring the goods and services we purchase, including office products, are sustainable; socio-economic issues, such as inequality, are addressed; and working conditions of suppliers' employees are acceptable. 

In addition, Ameren is keeping our downstream impacts in mind. Our Investment Recovery Program responsibly coordinates the selling and/or divestment of scrap, surplus, substation and distribution transformers and oil-filled electrical equipment, transmission material, energy center equipment, retired fleet and other assets, as part of our sustainability priorities.
