TRI tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. U.S. facilities in different industry sectors must report annually how much of each chemical is released to the environment and/or managed through recycling, energy recovery and treatment. (A "release" of a chemical means that it is emitted to the air or water, or placed in some type of land disposal.)
.
The information submitted by facilities is compiled in the Toxics Release Inventory. TRI helps support informed decision-making by companies, government agencies, non-governmental organizations and the public. The TRI Program's mission is to provide the public with information about TRI chemicals, including releases, other waste management (e.g., recycling), and pollution prevention from TRI-reporting facilities. To achieve this mission, the TRI Program:
Assists government agencies, researchers, and others in research and data gathering.
The vision for the Toxics Release Inventory is that TRI is recognized as a premier resource for accessing information on possible exposure to toxic chemicals and pollution prevention activities that can reduce this exposure.
