# EPD Search

> EPD Search is a public research and market-analysis interface for Environmental Product Declarations (EPDs), operated by improving sustainability GmbH.

The site aggregates declaration metadata from multiple programme operators. Data may be incomplete or inaccurate and should be verified against the original declaration before use. EPD values are not automatically comparable: declared units, functional equivalence, product scope, geography, reference period, PCR rules, standards, and life-cycle modules must align.
