Transformational Changes Toward Net-Zero Carbon Emissions

Ameren is committed to clean. The company has established a net-zero carbon emissions goal by 2050 across all its operations in Missouri and Illinois. In addition, Ameren laid out plans for 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 2050.

Ameren’s Plan Includes:

  • A commitment to a net-zero carbon emissions goal by 2050.
  • The company’s largest investments in renewable solar and wind energy in its history.
  • An investment of billions of dollars, creating thousands of jobs.
  • Meeting customers’ energy reliability needs while keeping rates affordable.

The clean energy expansion is included in Ameren Missouri’s Integrated Resource Plan (IRP). The IRP is a triennial filing that sets forth Ameren Missouri’s preferred plan to transform its electricity generation portfolio over the coming decades. It takes advantage of the continued decline in the cost to build new clean energy resources. To learn more about the plan’s key features and important milestones, read the plan summary

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

“Ameren’s new net-zero carbon goal for 2050 and the advancement of 2040 and 2030 goals by ten years is huge progress from where the company was just three years ago. It's a meaningful step in the Midwest in addressing climate change that builds on the company’s success in achieving the 2025 Paris targets five years early. Clean energy and energy efficiency investments of more than $5 billion in the next ten years will help our region's economic recovery, with energy efficiency and demand response programs saving the equivalent of two large power plants. With additional state and federal policy support, even greater emission reductions and economic benefits are possible.” – Ashok Gupta, Natural Resources Defense Council


“The Nature Conservancy of Missouri is encouraged to see Ameren’s vision and carbon-free goal. Reducing carbon emissions is critical to addressing climate change that impacts us all. In order to avoid the worst effects of climate change and help society and nature adapt to the impacts we are already experiencing, we must reach net zero emissions by 2050. The Nature Conservancy of Missouri stands ready to work with Ameren, state and local governments, and a wide cross-section of partners, to make this goal a reality by supporting the responsible deployment of renewable energy, retiring coal plants, and putting nature to work. Nature offers valuable climate solutions through conservation, restoration and improved land management of our forests, grasslands, and wetlands. Ameren’s carbon-free goal is pivotal for Missouri and provides opportunity for both people and nature to thrive.” – Adam McLane, State Director for The Nature Conservancy


"If 2020 has shown us anything else, it’s that the most challenged communities need increased, long-term support. Ameren has stepped up during the pandemic, and they’re leading the way in the future with their net-zero carbon emissions goal. The Urban League is dedicated to serving the African-American and other underserved members of our community. By investing in clean energy, creating jobs, continuing to build and develop diverse business suppliers, Ameren is showing the leadership needed to bridge the inequalities that exist in our communities.” – Michael P. McMillan, President and C.E.O., Urban League of Metropolitan St. Louis, Inc.


“I am delighted to see Ameren step up and put the pedal down on their switch to clean energy. More people than ever before are hurting due to the pandemic. This plan, and their continued support of community-based efforts to reduce the energy bills of our seniors and neighbors, come at the time when we need it most. I encourage Ameren to continue these efforts, with a continued focus on diversity of thought, equitable sharing of burdens and resources, and the intentional inclusion of those whose voice is often not heard.” – Rev. Earl E, Nance, Jr., Chair Emeritus & Corporate Treasurer, Heat-Up St. Louis, Inc. & Pastor, Greater Mount Carmel Missionary Baptist Church


"We are grateful and excited about Ameren’s efforts to create a healthier, more sustainable community through their net-zero carbon emissions goal. Ameren has been a long-standing partner of United Way and a strong champion of the St. Louis region, and this incredible initiative is one more example of their commitment to our neighbors. Through clean and reliable energy, advanced technology and the creation of local jobs, Ameren is paving a path to a better future for all St. Louis residents." Michelle D. Tucker, President & Chief Executive Officer, United Way of Greater St. Louis


“I applaud Ameren’s leadership in committing to a net-zero carbon emissions goal. Ameren is with us every step of the way as we work to get St. Louis County government on 100% renewable energy. Clean energy also means new jobs in St. Louis County. As a direct result of Ameren’s investments, residents will benefit from cleaner air, an even stronger grid and a stronger economy.” – Dr. Sam Page, St. Louis County Executive


"The foundation to reposition Missouri as an economic leader begins with reliable and affordable energy. Ameren has the plan to execute, and businesses across the state are encouraged by their leadership, job creation and investment in our state." – Dan Mehan, Missouri Chamber of Commerce and Industry


“Starting a long-term, post-pandemic recovery depends on secure, reliable and affordable supply of energy. Building sustained economic growth, especially for those hard-working men and women who have suffered from job loss and hardship, will be possible thanks to forward-thinking companies like Ameren.” – Chris Ventura, Executive Director, Consumer Energy Alliance - Midwest
