SEE our actions involving environmental stewardship

Balancing the needs of our environment, customers and economy is important to all of us at Ameren. We are building a legacy of environmental stewardship – preventing and controlling pollution, reducing greenhouse gases, creating renewable energy initiatives, and developing innovative technologies that help us operate cleanly. Here are a few of the many ways our actions are making a difference.

New CNG facility and vehicles demonstrate commitment to innovation, environment

Ameren Illinois unveiled its new compressed natural gas (CNG) refueling station in Maryville, along with seven new trucks that run on the alternative fuel, illustrating the company’s commitment to innovation and environmental stewardship.

Saint Louis Zoo Animals Enjoy All the Trimmings

A unique partnership between Ameren Missouri and the Saint Louis Zoo allows animals to enjoy a more nutritious diet while ensuring greater reliability for Ameren Missouri customers. Pruning and removing trees that threaten power lines is an important part of maintaining reliable service for customers. Each year Ameren Missouri trims about half a million trees along an average of 4,000 miles of power lines. Instead of chipping the clippings, we deliver them to the Saint Louis Zoo, where zoo animals enjoy them year round. Learn more about our tree trimming efforts at

Electric Vehicle
Expanding Electric Vehicle Use

Ameren is growing demand for electric vehicles through numerous avenues. We're advocating for the expansion of charging stations for all customers, installing more charging islands at Ameren-owned facilities, and pursuing options to transition both our own and our customers' fleets.

Falcon Cam

In 2017, five Peregrine falcons hatched high above Sioux Energy Center, tying an Ameren Missouri record for chicks hatched in one year. Peregrine falcons have now raised 24 chicks inside a nesting box at Sioux Energy Center. The popular FalconCam live-streaming camera received nearly 2,000 views a day over a two-month span when the eggs were laid and the chicks hatched. Many more falcons were born and raised above the Labadie and Rush Island energy centers. Working in partnership with the Missouri Department of Conservation and the World Bird Sanctuary, the falcons were banded for future research on the species.

Rails to Trails

In summer 2018, Ameren is slated to finish years of vegetation and salvage work and officially transfer a 144-mile stretch of the former Rock Island rail line to the state of Missouri. We are excited to see communities enjoy the new world-class hiking and biking trail and benefit from a boost in tourism and economic development.

Shoreline Management

Ameren Missouri oversees shoreline management at the Lake of the Ozarks under provisions of our operating license for Bagnell Dam and the Osage Energy Center. This year marked the 26th anniversary of the Adopt-the-Shoreline Cleanup. In 2017, volunteers removed more than 53 tons of trash, which is an increase of nearly 10 percent from 2016. Ameren Missouri sponsors the cleanup, providing administrative support and trash bags as well as paying for disposal.

Planting Trees

Each year, Ameren Illinois partners with local communities to replace trees that were damaged or uprooted during major storms. Ameren Illinois provides financial grants to purchase new trees, and employees work with local volunteers to re-plant them in the community.

Managing Vegetation

Managing vegetation on rights-of-way along power lines enhances safety and helps prevent vegetation-related service interruptions, especially during severe weather. Our vegetation program not only increases reliability, but uses sound arboriculture practices—promoting healthier forests and sustainable compatible vegetation. Additionally, we modify structures and/or install equipment that helps avian wildlife to co-exist with our facilities.

Water Conservation

Limiting water usage is an everyday practice at Ameren. It is essential to our daily lives. Ameren is committed to conservation efforts throughout our service territory.

Green Building Efforts

The Hub, home of Ameren's innovation initiatives, has received special recognition from the U.S. Green Building Council (USGBC). The building is now Leadership in Energy and Environmental Design (LEED) Gold certified, and becomes Ameren's first building to receive that designation. As the most widely used green building rating system in the world, LEED provides a framework to promote healthy, highly efficient and cost-saving green buildings. Originally, the building was a 1930s-era movie theater.


Promoting Pollinators

More than 60 second graders rolled up their sleeves to help Ameren Transmission and the Saint Louis Zoo cultivate pollinator habitats on Ameren Transmission rights of way in St. Louis County. The students from Parkway School District helped spread flower and natural grass seeds to promote feeding opportunities for bees, birds, butterflies and other pollinating insects.
