Why This Report Matters
The U.S. utility sector is at a turning point. As pressure builds to transition to carbon-free energy, this report offers a transparent, side-by-side look at which investor-owned utilities are truly making progress.
From emissions intensity to carbon-free investment, it empowers decision-makers across the utility ecosystem—policymakers, sustainability officers, regulators, and investors—with the insights they need to move forward confidently.
Accountability
Comparative rankings create transparency across 47 top utilities—tracking emissions, investment, and progress.
Decarbonization Insights
See how utilities are transitioning their fuel mix and reducing carbon intensity across Scope 1, 2, and 3.
Informed Action
Use the data to inform policy, investment, or internal decarbonization strategies with confidence.
Spotlight on Public and Gas Utilities
This year’s report shines a light on utilities often left out of national climate benchmarks. Public utilities and natural gas providers serve millions of customers and will play a key role in decarbonization. Their inclusion reflects NPUC’s belief that a full-sector transition is only possible through collaboration across all utility types.
