Global Climate Change


Ameren has set ambitious goals to guide us on our path to a sustainable energy future. We strive to achieve net-zero carbon emissions by 2045, enabled by expanding our renewable energy resources without compromising on affordability and reliability. Our goal is to reduce carbon emissions 60% by 2030 and 85% by 2040, from 2005 levels. The new goals accelerate and expand on our 2020 pledge and are consistent with the objectives of the Paris Agreement in limiting global temperature rise to 1.5 degrees Celsius.

Ameren’s Strategy to Address Global Climate Change
