On March 20, 2007, the Woodrow Wilson International Center for Scholars Project on Emerging Nanotechnologies (PEN) released a report entitled Nanotechnology and Life Cycle Assessment: A Systems Approach to Nanotechnology and the Environment, which summarizes the results of the October 2-3, 2006, workshop organized by PEN and the European Commission on life cycle assessment (LCA). LCA is a cradle-to-grave analysis of how a material affects ecosystems and human health. According to the report, the purpose of the October 2-3, 2006, workshop was to determine whether existing LCA tools and methods are adequate to use on a new technology. The report provides an overview of LCA and nanotechnology, discusses the current state of the art, identifies current knowledge gaps that may prevent the proper application of LCA in this field, and offers recommendations on the application of LCA for assessing the potential environmental impacts of nanotechnology, nanomaterials, and nanoproducts.
