Environmental Product
Declarations

An Environmental Product Declaration (EPD) is a voluntary, independently verified report regarding information about the life-cycle of products and their environmental impact. EPDs address energy use, emissions, processing of raw materials, and transportation.

More information on EPDs can be found on the  ASTM International website.
