Environmental Product Declarations, or EPDs®, are statements that reflect what a product’s life cycle and its related impact on the environment will be. The statements are verified independently, usually through testing by a third-party company. They are registered and contain specific, clear information that can be compared with similar products. The most commonly recognized EPD for windows and glazing are ASTM ISO 14025 and EN15804. EPDs were introduced in 2002.
