EPA Releases Preliminary 2024 TRI Data

Released Aug. 5, 2025

Today, the U.S. Environmental Protection Agency (EPA) published preliminary Toxics Release Inventory (TRI) data about chemical releases, waste management and pollution prevention activities that took place during 2024 at more than 21,000 industrial and federal facilities across the country.

EPA is also making a routine update to its online TRI tools to include new reporting from submissions, revisions and withdrawals from 2023 and earlier that EPA has processed since October 2024. These updated data are, in part, the result of EPA’s work to assist industrial facilities in collecting and submitting accurate TRI data.

General Information on the 2024 Preliminary Data

The 2024 preliminary data were reported by facilities in covered industries that manufactured, processed, or otherwise used substances on the TRI chemical list above threshold quantities during 2024.

The dataset released today contains data as submitted by facilities and does not include any summary or trend analysis. While the preliminary data have not been through the complete TRI data quality process, the reporting software (TRI-MEweb) that facilities used to submit these data includes many automated quality checks that help prevent common mistakes during data entry. EPA is conducting additional quality checks to identify suspected reporting errors and follow up with facilities if data quality issues are identified. For details about the TRI data quality process, see the TRI Data Quality webpage.

EPA plans to publish a revised version of the dataset later this year, which will include late submissions and revisions submitted by facilities. The preliminary data are accessible on EPA's Envirofacts website. They are also available for download from the TRI website.
