Dispersed in-state reporter mix
ENTERGY is the largest single reporter at 11.9% of Louisiana CO₂e (17.7M MT), but the top three still account for only 24.2% across 165 parent companies. Shares use EPA GHGRP facilities sited in LA only, not each parent's company-wide total.
- Louisiana is 5.8% of the 2.57B MT U.S. GHGRP facility rollup across 54 jurisdictions.
- Leading EPA sector by CO₂e: Chemicals at 39.6% (59.0M MT across 83 facilities) - orthogonal to the facility-count sector mix below.
- Trails Texas by 256.6M MT on the same state ranking.
- Leads Pennsylvania by 31.7M MT on the same state ranking.

Company footprint
Which companies combine scale and emissions?
Each point is a leading Louisiana 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 Louisiana.
