Abstract: To perfect the data available for product life cycle assessment (LCA) in the current enterprise resources planning (ERP) systems, such as materials, products, technical process, transportation and solid waste, the framework of an ERP system supporting LCA was proposed. In this system, by adding an environmental function module, it can track, analyze and control environmental data for product production continuously and automatically gather the data for LCA. As a result, a new approach of implementing LCA and environment management was provided.
