The LCA and Technology Assessment Department continues a 32-year history of leadership in the field of life cycle assessment. The Researcher will join project teams including experts in a variety of topics and will regularly collaborate with experts of other Argonne groups as well as in industry and at other national laboratories. The Department develops and maintains the Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) model, which is widely used by government, industry, and academic stakeholders to provide objective and rigorous results (see https://greet.anl.gov). The Department supports DOE and other sponsors to assess the energy and environmental impacts associated with energy systems, chemicals, products, materials, and integrated systems to help DOE and other stakeholders guide R&D efforts, identify improvement opportunities, and propose new methodologies to address emerging issues in LCA.
