A single visual combines emissions intensity, target timing, and disclosure breadth for 47 U.S. investor-owned utilities, revealing where low carbon intensity, early targets, and comprehensive Scope 3 reporting overlap — and where they don’t.
PSEG, Avangrid, and PG&E report the lowest emissions intensity among the 47 utilities analyzed, with PSEG’s intensity reported as 0.0001 tCO₂e/MWh.
Net-zero target decades vary widely: Avangrid targets the 2030s, several utilities target the 2040s, but many set goals in the 2050s or have no net-zero target.
Scope 3 reporting coverage differs a lot: TransAlta reports 11 Scope 3 categories, Southern Company reports 10, while some utilities report zero or only one category.

Key Takeaways PSEG has the lowest emissions intensity among the major investor-owned utilities in the U.S., followed by Avangrid and PG&E. Avangrid sits in the 2030s target group, the earliest decade shown in the dataset.
However, more categories do not automatically indicate greater transparency because not every Scope 3 category applies equally to every utility. TransAlta reports 11 Scope 3 categories, the broadest coverage shown. power sector is balancing rising electricity demand with the push toward lower-carbon generation.
PSEG, Avangrid, and PG&E stand out for low reported emissions intensity. Separately, the California Energy Commission reports that PG&E-owned Diablo Canyon supplies about 17% of California's zero-carbon electricity, adding context to the utility's low reported emissions intensity. Meanwhile, renewables have reached new highs in U.S.
