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