Dispersed in-state reporter mix
CLEVELAND-CLIFFS is the largest single reporter at 12.9% of Indiana CO₂e (14.3M MT), but the top three still account for only 30.4% across 119 parent companies. Shares use EPA GHGRP facilities sited in IN only, not each parent's company-wide total.
- Indiana is 4.3% of the 2.57B MT U.S. GHGRP facility rollup across 54 jurisdictions.
- Leading EPA sector by CO₂e: Power Plants at 49.6% (55.4M MT across 44 facilities) - orthogonal to the facility-count sector mix below.
- Trails Florida by 4.0M MT on the same state ranking.
- Leads California by 8.5M MT on the same state ranking.

Which companies combine scale and emissions?
Each point is a leading Indiana 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 Indiana.
