Pollution Prevention (P2) and TRI
Under the Pollution Prevention Act of 1990 (PPA), the Toxics Release Inventory (TRI) Program collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives. Many facilities provide descriptions of measures they have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment. As a result, TRI serves as a tool for identifying effective environmental practices and highlighting pollution prevention successes.
