TRI for Government

EPA uses Toxics Release Inventory (TRI) data to inform the scientific documents, policies and technical assistance efforts of various programs. Many other government organizations at the Tribal, federal, state and local levels also use TRI data. The TRI allows government agencies to identify sources of toxic chemical releases that may impact the health of their communities, track changes in these releases over time and prioritize efforts to reduce pollution from nearby facilities.

How Can Governments Use TRI Data?

TRI tracks the management of certain toxic chemicals that may pose a threat to human health and the environment from TRI-reporting industrial facilities. TRI tools allow for online exploration or download of all reported data and summarize information for different geographies (e.g., ZIP code, city, state), chemicals, industries and facilities.

Governments can use TRI data to:

Identify TRI-reporting facilities that operate in an area and what chemicals they release,
Track changes in releases and other waste management quantities over time to help measure environmental performance,
Prioritize pollution prevention assistance efforts to facilities in an area,
Inform siting or permitting decisions,
Help plan for chemical-related emergencies,
Promote public awareness of the availability of environmental information,
Incorporate TRI data as a metric in analyses of local health and environmental conditions, and
Inform the development of regulations, guidelines, or standards.

The TRI Data Exchange is EPA's method for providing U.S. states, territories, and Tribes with real-time access to TRI data. Join TDX by signing a Memorandum of Understanding (MOA) with EPA.

Tribal Governments

In 2023, there were 2,143 facilities on or within 10 miles of the lands of 250 Tribes. These facilities reported a total of 230 million pounds of releases. The TRI for Tribes webpage provides resources such as tips for exploring the TRI Tribal dashboard, summary information, and contact information. Learn more about how TRI data can support Tribes.

International Chemical Release Reporting

Pollutant Release and Transfer Registers (PRTRs) are the data collection systems that track releases of pollutants into the environment and transfers of pollutants off site for waste disposal or other management. The TRI is the U.S. PRTR system, after which many other countries have modeled their programs. Currently, at least 50 countries have fully established PRTRs or have implemented pilot programs. Learn more about international PRTRs.

Governmental Data Use Spotlights

Spotlight: U.S. Army Uses TRI Data in Sustainability Report

TRI data are one metric the U.S. Army uses to evaluate its progress toward achieving sustainability goals. The Army's 2009 sustainability report cited a reduction in pounds of chemical releases. Access the report.

Spotlight: Kentucky Publishes State-Specific TRI Analysis

This graph shows the trends in air, water, land and total on-site disposal of toxic chemicals reported to TRI in Kentucky from 1988 through 2020.

State agencies often conduct assessments of chemical releases reported by facilities located within their states.

Kentucky’s Energy and Environment Cabinet publishes an annual summary and analysis of TRI data. The report highlights the top chemicals released into the air, water and land; trends in releases over time; and rankings of facilities based on quantities of releases and off-site transfers. Access the reports.

Spotlight: EPA Uses TRI Data to Evaluate Green Chemistry Practices

Various programs in the EPA use TRI data in publications, data access tools, agency reports, and pollution prevention technical assistance, among other purposes.

In a 2015 study, the EPA used TRI data to analyze pharmaceutical firms’ claims that implementation of green chemistry practices in their manufacturing processes significantly reduced the quantities of toxic chemicals used and released into the environment. Read the publication.
