ELSI will be included in the risk assessment process. (5) Life cycle assessment (LCA) LCA will be used to develop standard impact assessment procedures for nanoproducts; The Taiwan EPA will continue to gather data for nanomaterials flow and its impacts based on the existing ISO framework (ISO14040: 2006) for LCA; to assess potential risks and environmental impacts of nanoproducts; to develop screening tools for ecology compatible designs; to assist in assessing green nanotechnology products based on LCA and avoiding unforeseeable accidents.
