This partial disclosure allows for some insight into the company's indirect impacts.
In 2023, the largest contributors to Ameren's Scope 3 emissions were:a
In 2023, Ameren reported Scope 1 greenhouse gas (GHG) emissions of 19,883,180 tCO₂e and total revenues of USD 7,500 millions. This translates into an emissions intensity of 2,651.09 tCO₂e per millions USD.a
In 2023, Ameren reported a Scope 1 emissions intensity of 2,651.09 tCO₂e per millions USD. Compared to the peer group median of 2,141.58, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2023, Ameren ranked 20 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Ameren is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2023, Ameren reported a total carbon footprint of 36,567,973 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 21.42% decrease compared to 2022, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Ameren's total carbon footprint was Scope 1 emissions, accounting for 54.37% of the company's total carbon footprint, followed by Scope 3 emissions at 45.39%.a
