The Toxics Release Inventory (TRI) is a powerful resource that provides the public with information about how TRI chemicals are managed by industrial facilities in the United States. However, there are many other programs at EPA that collect information about chemicals and the environment.

The next figure is an overview of some of the laws that EPA implements, and the industrial activities or processes EPA regulates under these laws. While many programs at EPA focus on one area, TRI covers releases of chemicals to air, water, and land; waste transfers; and waste management activities. As a result, TRI data are especially valuable, as they can be utilized with many other datasets to provide a more complete picture of national trends in chemical use, chemical management, environmental release and other waste management practices, and environmental performance.


Throughout EPA, offices use TRI data to support their mission to protect human health and the environment. These uses include analyzing TRI data to inform decisions such as when setting program priorities, providing information to stakeholders such as when working with communities toward a common goal, and many other applications as shown in the table below.

This section of the National Analysis highlights how TRI data complement TSCA data and evaluations, and how TRI has served as a model for other pollutant release inventories around the world.

This page was published in January 2018 and uses the 2016 TRI National Analysis dataset made public in TRI Explorer in October 2017.
