This document provides general environmental data relevant to mechanical products. It can be applied to a mechanical product as well as to parts of a mechanical product. The aim is to provide guidance values to entities, e.g. manufacturers, supporting ¯# design or re-design choices for products (e.g.: to compare technical solutions) by providing a complementary environmental criterion in a multicriteria approach; ¯# enhancement of knowledge on products from an environmental perspective (simplified environmental performance assessment). These data cover the most relevant aspects for the mechanical sector: material, processes, energy, transportation and end of life of products. They provide an order of magnitude of impacts and cannot be considered as absolute values because many parameters can influence the obtained results (geographical and technical perimeters, use scenarios, hypothesis and method of calculation, etc.). They are not intended to replace specific data obtained or used by entities as part of individual projects. They are not intended to be used as such: ¯# quantification of environmental impacts within a life cycle analysis (LCA) according to EN ISO 14040/EN ISO 14044, ¯# environmental communication as defined in EN ISO 14025 (Type III environmental declaration), ¯# evidence of regulatory compliance.
