The map is a visual summary; every value is in the table below, which is the keyboard and screen-reader path. Groups are quintiles of the values shown (a derived grouping). Boundaries: Natural Earth (public domain), simplified. Alaska and Hawaii are shown as insets, not to scale.

Rank is derived by Quadranac: 1 = highest value; ties share a rank. Values are as published in the source table.

Note: Emissions are counted where fuel is burned, so states that generate electricity or refine fuel for others have high per-person figures. Data are for 2022, EIA's latest state series.
