Toxics Release Inventory (TRI)

Description

The Toxic Release Inventory (TRI) compiles the data on toxic chemical releases and waste management activities reported annually by certain industries as well as federal facilities and makes it available through downloadable files and several data access tools. The goal of TRI is to provide communities with information about toxic chemical releases and waste management activities and to support informed decision making at all levels by industry, government, non-governmental organizations, and the public. TRI contains information on releases of nearly 650 chemicals and chemical categories from industries including manufacturing, metal and coal mining, electric utilities, and commercial hazardous waste treatment, among others.
