International scientific bodies recognize the critical role that the US electricity sector plays in meeting the Paris Agreement’s goals of limiting global temperature rise. For example, according to the International Energy Agency (IEA), reaching global net zero emissions for the energy sector by 2050 requires “overall net zero emissions electricity in advanced economies,” such as the US, by 2035.[1] Meeting the Paris Agreement’s goals is necessary to avoid increasingly severe climate risks for companies and investment risks for investors.

Alliant aspires to achieve net-zero greenhouse gas emissions from its utility operations by 2050 and has a goal of 50% reduction by 2030 from a 2005 baseline.[2] Alliant has not disclosed other interim targets. However, Alliant has not obtained independent third-party validation that its targets are based on sound methodology and actually aligned with the Paris Agreement goals.

The Transition Pathway Initiative (TPI) recently conducted an assessment utilizing the IEA Net Zero Scenario (the most broadly accepted and globally used scenario for assessing the pace of the energy transition and Paris-alignment) and found that Alliant’s 2030 target is not in alignment with the Paris Agreement’s goals of limiting global temperature rise. For example, according to TPI’s comparison to North American benchmarks, the carbon intensity of Alliant’s published 2030 target may be as much as 5.9 times the level consistent with limiting global average temperature rise to 1.5 degree Celsius and more than 4 times the level consistent with Below 2 Degrees outcomes.[3]

As a result, long-term investors are concerned that Alliant targets may not be aligned with Paris agreement goals and believe that Alliant disclosure of independently evaluated targets is a credible way to address these concerns.

We urge shareholders to vote FOR the proposal.
