In-state concentration desk
THE SOUTHERN accounts for 17.1% of reported Mississippi CO₂e (7.3M MT of 42.5M MT). The top three in-state reporters hold 44.3% (THE SOUTHERN; US GOVERNMENT; NEXTERA ENERGY). Shares use EPA GHGRP facilities sited in MS only, not each parent's company-wide total.
- Mississippi is 1.7% of the 2.57B MT U.S. GHGRP facility rollup across 54 jurisdictions.
- Leading EPA sector by CO₂e: Power Plants at 65.8% (27.9M MT across 24 facilities) - orthogonal to the facility-count sector mix below.
- Trails Wisconsin by 1.5M MT on the same state ranking.
- Leads Colorado by 1.2M MT on the same state ranking.

Company footprint
Which companies combine scale and emissions?
Each point is a leading Mississippi reporter. The crosshairs mark the median among the companies shown, so the chart distinguishes a larger facility footprint from a higher emissions total.
This is a comparison of the leading 12 reporters displayed above, not a measure of production, population, or total company-wide emissions outside Mississippi.
