* Split: if 50% appears in this column, then the facility's emissions have been split among two 50/50% ownership parent companies.

*** Biogenic CO2 has not been included within the emissions totals anywhere else in this application.

**** "Other emissions" include HFCs, NF3, PFC, SF6, and other fluorinated gases.

The Toxic Air score column shows the facility's total chronic human health air toxicity score if the facility also exists in the Toxic 100 Air database.
