For explanations of most columns above, including the EJ Shares, see the technical notes.

The Greenhouse CO2e column shows the CO2 equivalent pounds released by this facility if the facility also exists in the Greenhouse database

* Split: if 50% appears in this column, then the facility's emissions have been split among two 50/50% ownership parent companies for their parent company data, although the full pounds and score are displayed here.
