Despite the prevalence of climate targets, the report shows that most commitments amount to little more than greenwashing. Utilities often set distant net-zero deadlines—such as 2045 or 2050—without actionable interim plans. The report emphasizes that only companies with ambitious, near-term goals, like cutting emissions 80% by 2030, demonstrated measurable progress.
For example, Xcel Energy has maintained its 2018 pledge to reduce emissions 80% by 2030 from a 2005 baseline. Backed by tangible clean energy investments, the utility earned a B rating this year, outperforming peers with weaker or shifting commitments.
The most alarming trend is utilities rolling back prior commitments:
Such reversals reflect what the report describes as “a failure to make realistic plans years ago to meet their own goals.” Instead of building momentum, these companies cite timing and cost as excuses.
The Sierra Club’s methodology is rooted in climate science benchmarks and hard data on utility planning:
Grading scale: ≥75 = A, 50–74 = B, 35–49 = C, 17.5–34 = D, <17.5 = F. The national aggregate score in 2025 was 15/100, a failing grade.
This framework reveals that utilities with ambitious interim targets (such as 80% GHG reduction by 2030) consistently scored higher than peers leaning on vague 2045–2050 net-zero claims.
These shifts have implications beyond climate. Greenwashing can mislead investors seeking credible ESG performance and leave ratepayers exposed to rising costs. Energy Innovation estimates that reduced clean energy deployment could raise U.S. wholesale power prices by 50% by 2035.
In states like Kansas and Missouri, where Evergy operates, low-income and minority households already face some of the nation’s highest energy burdens. Delays in coal retirements and new investments in gas could lock in higher bills for decades.
The Sierra Club’s analysis underscores that vague pledges are not enough. Utilities that commit to near-term, science-aligned targets—such as Xcel’s 80% by 2030—score substantially higher than those without concrete milestones.
