The EPD is an important voluntary instrument for companies that want to play an active role in managing environmental factors. The EPD is a document that provides detailed, credible and verifiable information about the environmental performance of the life cycle of products and services. EPDs are certified by a third party and enable comparisons over time and between products. The presence of shared rules (Product Category Rules or PCRs) from a qualified and authoritative management body and a reliable shared system constitute fundamental elements in guaranteeing and protecting EPD users. The EPD makes explicit use of the LCA methodology, the cornerstone on which the declaration and methodological foundation is based, guaranteeing the scientific rigour of the information provided. On a national level Novamont has made an active contribution to the development and promotion of EPD systems, participating in a pilot project in 2000-2001 organised by the Italian Agency for Environmental Protection – ANPA (now the Institute for Environmental Protection and Research – ISPRA) to draft guidelines for a national certification system which produced two PCRs and two EPDs. On an international level, Novamont was a partner in the Life INTEND project for the development of an international EPD system which resulted in one PCR and one EPD. In 2006 Novamont jointly participated in the development of a PCR for biodegradable plastic bags, and in 2010 it helped draw up a new PCR for plastic materials developed in accordance with the new criteria of the international system for EPDs.
