About EPA

The EPA's Developer Central provides a set of embeddable widgets and public APIs for accessing federal environmental data, primarily built around the Envirofacts system. These cover topics such as air quality (ICIS-Air), water systems (Safe Drinking Water Information System, RadNet), waste and cleanup programs (Superfund, RCRA, Brownfields), toxics and chemical reporting (Toxics Release Inventory, Toxic Substances Control Act), greenhouse gas reporting, facility registries, and compliance history (Enforcement and Compliance History Online).

Additional widgets support location- and search-based lookups (city, county, state, zip, and tribe search), a greenhouse gas equivalencies calculator, a job search tool, and program-specific resources like Safer Choice and WaterSense labeling.

The page is intended for developers who want to embed EPA data and tools into their own websites or applications, with links to the underlying public APIs and a System of Registries for further reference.
