Environmental Product Declarations (EPD) present the results of a life cycle assessment (LCA) carried out on a product to quantify its environmental impacts. EPD’s are prepared according to strict rules defined by the EPD Programme Operators and are based on ISO 14025 and EN 15804 standards.

The EPD’s which EPPA (European Trade Association of PVC Window System Suppliers) published for double-glazed and triple-glazed PVC windows, summarize the environmental impact of PVC window profile systems available on the EU market.
