Transformational Changes Toward Net-Zero Carbon Emissions

Ameren is committed to clean. The company has established a net-zero carbon emissions goal by 2045 across all its operations in Missouri and Illinois. In addition, Ameren is making progress on its largest-ever expansion of clean wind and solar generation that maintains the reliability and affordability that customers have come to expect.

Invested In a Clean Energy Future

At Ameren Missouri, we're committed to getting the energy we provide as clean as we can, as fast as we can, while maintaining the reliability our customers depend on. With a transformative expansion of wind and solar energy, Ameren Missouri has a responsible plan to reach net-zero carbon emissions by 2045. This goal includes both Scope 1 and 2 emissions including other greenhouse gas emissions of methane, nitrous oxide and sulfur hexafluoride. We're also targeting a 60% reduction in carbon emissions by 2030 and an 85% carbon emissions reduction by 2040, based on 2005 levels. These goals are dependent on a variety of factors including cost-effective advancements in innovative clean energy technologies as well as constructive federal and state energy and economic policies.

Ameren’s Plan:

  • Safeguards energy reliability and resiliency for customers while focusing on affordability.
  • Commits to an accelerated goal of net-zero carbon emissions by 2045.
  • Increases renewable solar and wind energy generation additions by 2030.
  • Invests billions of dollars, creating thousands of jobs.

The clean energy expansion is included in Ameren Missouri’s Integrated Resource Plan (IRP). The IRP sets forth Ameren Missouri’s preferred plan to transform its electricity generation portfolio over the coming decades.

Climate, community and energy leaders from across the country are supportive of Ameren's updated goals and renewable energy plans:

"Southeast Missouri State University is proud to be an Ameren Missouri customer and a partner on the Neighborhood Solar project being constructed on our main campus in Cape Girardeau. This project will bring clean, renewable solar energy to our community, including our university. The solar panels also provide covered parking at the Show Me Center. We are excited and thankful for these benefits which are part of Ameren Missouri's Smart Energy Plan and the company's efforts to bring more green energy to the grid as part of its commitment to a net-zero carbon emissions goal by 2045. This project represents meaningful progress that will impact our students, our state, and our energy future." – Dr. Carlos Vargas, President, Southeast Missouri State University

"We rely on energy for so much in our daily lives. We count on reliable electricity to provide lighting, heating and cooling for our homes and businesses; power our many devices; and provide energy to our factories that manufacture products and provide jobs. With so many states announcing the likelihood of summer brownouts or blackouts, it is important that we recognize Ameren Missouri for always providing safe, secure and stable energy for its millions of customers and for bringing more renewable energy into their generation mix as they look to the future." – Chris Ventura, Executive Director, Consumer Energy Alliance – Midwest

“The Missouri Chamber recognizes the advantage of reliable, resilient and affordable electricity and natural gas in retaining and attracting business to our state. The Missouri Chamber supports Ameren Missouri's all-of-the-above approach to electricity generation including coal, natural gas, nuclear, hydro and renewable sources as they make the transition to clean energy. We also support their grid modernization efforts that drive greater resiliency, rate affordability and economic development opportunities." – Dan Mehan, Missouri Chamber of Commerce and Industry
