While many of us are giving thanks to Ameren Missouri for heating our homes as frigid temperatures  settled in the region, you might also be interested to learn about their outstanding commitment to keep pace with future energy needs by implementing green business practices.

A returning participant of the St. Louis Green Business Challenge, Ameren Missouri was recognized as a Challenge Champion for completing work with the Leader scorecard in past years and committing to continued implementation of deeper sustainability strategies. During the 2020 Challenge, Ameren Missouri elected to develop and report on their Champion Innovation Project – Advancing Our Sustainability Initiatives – that focuses on the company’s internal greening efforts and customer-based work.

As part of the St. Louis-based Ameren Corporation, Ameren Missouri has been providing electric and gas service for more than 100 years, powering the quality of life for 1.2 million electric and 130,000 natural gas customers in central and eastern Missouri. The company is proud to serve, support and invest in the communities they call home, and they also value the importance of balancing the needs of our environment, customers and economy. From preventing and controlling pollution, reducing greenhouse gases and creating renewable energy initiatives to developing innovative technologies that help the company operate cleanly, Ameren Missouri is dedicated to building a legacy of environmental stewardship.

Additionally, the company is taking transformative steps towards net-zero carbon emissions by 2050. Last year, the company published its award-winning 2020 Sustainability Report, which is a comprehensive view of action taken on key environmental, social and governance (ESG) matters. Ameren Missouri announced more than 75% of their current coal-fired energy centers will be retired by 2040, with all centers being retired by 2042 to help reduce harmful emissions and improve air quality. While building on their existing carbon free initiatives, they also announced plans to add 3,100 megawatts of new clean, renewable generation by 2030 and a total of 5,400 megawatts by 2040.

Through Ameren Missouri’s CommunitySavers® Program, property owners, community managers and income-eligible customers can receive energy-saving products for their home, along with rebates when they make eligible energy efficient upgrades. In 2020, the program distributed 240,000 LEDs and 1,700 window AC units to income-eligible customers. The company also announced it will invest $240 million through the year 2024 to fund energy efficiency and demand response programs though BizSavers®, Residential and Community Savers® programs.

To further reduce environmental impact, Ameren Missouri updated parking areas with new electric vehicle charging stations, introducing 65 co-worker spaces at their St. Louis Headquarters and 27 spaces at other facility locations to support regional electrification initiatives. Moreover, the company established a Fleet Electrification Goal for 100% of new light-duty vehicle purchases by 2030 to be electric, in addition to setting a goal for 35% of overall vehicle fleet to be electrified by 2030.
