Toxics Release Inventory

The Toxics Release Inventory (TRI) is an environmental management tool that collects data from industrial facilities about the amounts of toxic chemicals they release into the environment—such as air emissions, water discharges, or waste disposal—annually. This public database helps communities, regulators, and researchers monitor pollution sources, understand environmental health risks, and encourage industries to reduce harmful chemical releases. By promoting transparency and accountability, TRI supports efforts to improve environmental safety and protect public health.
