    • Clean Air Markets Program Data Application (CAMPD)

    Metadata Updated: February 10, 2026

    The Clean Air Markets Program Data (CAMPD) application, accessible at https://campd.epa.gov/, allows users to view Clean Air Markets data through the Custom Data Download Tool and Bulk Data Files. These tools are driven by APIs documented in the CAM API Portal https://www.epa.gov/airmarkets/cam-api-portal, which is accessible through CAMPD. The Custom Data Download Tool and APIs allow users to create custom queries to explore CAMD’s database through different data types: emissions, allowances, compliance, and facility attributes. Prepackaged Bulk Data Files are also available for commonly requested datasets and larger data downloads. EPA's Clean Air Markets Division (CAMD) manages several market-based regulatory programs designed to improve air quality and ecosystems. The most well-known of these programs are EPA's Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR) Programs, which reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)-compounds that adversely affect air quality, the environment, and public health.
