Targeting Net-Zero Carbon Emissions by 2045

Ameren's companywide goal of net-zero carbon emissions by 2045 is science based and consistent with the objectives of the Paris Agreement and limiting global temperature rise to 1.5 degrees Celsius. This goal encompasses both Scope 1 and Scope 2 emissions, including other greenhouse gas emissions of methane, nitrous oxide and sulfur hexafluoride. This goal is 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. Interim targets include reducing carbon emissions 60% by 2030 and 85% by 2040, in each case based on 2005 levels.
