Protecting the environment

We know that affordable, reliable, safe and efficient natural gas is key to a sustainable energy future. That's why we're focused on key initiatives like pipeline upgrades, energy efficiency programs and alternative energy sources that help protect the planet for future generations.

Environmental commitment

We were one of the first natural gas companies to commit to becoming a carbon neutral company by midcentury, leading the way for others to join us in the effort to care for our planet.

Reducing methane emissions

Since 2005, we've reduced methane emissions from gas utilities (mains and services) by more than 51%, and by 2035, we're targeting a cumulative 73% reduction in emissions.

Weatherization

We offer no-cost support to help customers on a fixed or limited income weatherize their homes. A weatherized home can reduce the average annual fuel usage by 35%.

Honoring our commitment

Since appointing Nick Popielski—now vice president of sustainability—as our first Head of Environmental Commitment in 2021, we now have a dedicated team established to analyze our business, understand our carbon footprint and implement our strategy and roadmap to meet our environmental goals by midcentury.

Supporting our communities
When we can support the places we call home, while caring for the environment, it's a win-win. Here's a look at some of the organizations we supported this past year.

Forest ReLeaf of Missouri

Through a Spire grant, Forest ReLeaf of Missouri was able to purchase, deliver and plant 1,900 trees in Missouri communities that were impacted by construction work and severe weather over the last two years. These trees will offset more than four million pounds of CO2 over 30 years.

Cahaba River Society

We continued our multi-year partnership with Cahaba River Society by sending teams of employees to remove evasive plant species along the Cahaba River, the longest substantially free-flowing river in Alabama.

Missouri River Relief

Teams of Spire employees, in partnership with Missouri River Relief, helped remove trash and flood debris along the banks of the Missouri River in western Missouri and the Mississippi River in eastern Missouri.

Forest Park Forever 

Spire partners with Forest Park Forever, a St. Louis-based non-profit committed to preserving and sustaining the number one park in America, to help St. Louis save precious natural resources.

Exploring alternative and renewable energy sources
Part of our strategy to reduce greenhouse gas emissions includes evaluating alternative energy sources, such as renewable natural gas (RNG) and hydrogen.

Renewable natural gas (RNG)

RNG is generated from purifying methane from existing waste streams like landfills, farms, wastewater and food waste. We're currently exploring projects to bring RNG to Missouri. 

Hydrogen

We're currently studying hydrogen and its potential ability to be used as an alternative energy source for our gas distribution system.
