Explanatory notes (also see the technical notes):

Toxic score: Population health risk from air releases and incineration transfers reported to the US Environmental Protection Agency's Toxics Release Inventory (TRI) for the 2006 Reporting Year, as computed by the US EPA's Risk-Screening Environmental Indicators (RSEI ver. 2.2.0) from quantity released, toxicity of chemicals, and population exposure.  Data are adjusted by the Corporate Toxics Information Project for subsequent revisions to TRI data. Source: US EPA and Corporate Toxics Information Project (CTIP).

Quantity of toxic air releases and incineration transfers: Millions of pounds of toxic chemicals released to the air on-site or transferred off-site for incineration in the TRI 2006 Reporting Year, without adjustment for toxicity or population exposure. Source: US EPA.

Environmental Justice (EJ): Poor Share and Minority Share: Shares of the total population health risk borne by people living below the poverty line or by people in minority racial/ethnic groups. In the U.S. population, 12.9 percent live below the poverty line and 31.8 percent are members of minority racial/ethnic groups. Sources: US EPA, US Census 2000, and CTIP.

Coverage: This table presents the highest toxic-score companies that appear on current Forbes, Fortune, and Standard & Poor's large company lists. Individual facilities are assigned to corporate parents on the basis of the most current information on the ownership structure. Source: CTIP.
