TRI Data and Tools

The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals that may cause harm to human health and the environment.

TRI data are reported by certain industrial and federal facilities. EPA makes these data available through multiple online tools, many of which add context to help make the reported data more understandable.
