TRI Data and Tools
The TRI Program tracks the management of toxic chemicals that may pose a threat to human health and the environment. Facilities in certain industry sectors report annually the volume of toxic chemicals managed as waste--recycled, treated or burned for energy recovery--as well as disposed of or otherwise released into the environment.
