NREL and its partners created the U.S. Life Cycle Inventory (LCI) Database to help life cycle assessment (LCA) practitioners answer questions about environmental impact.

This database provides individual gate-to-gate, cradle-to-gate and cradle-to-grave accounting of the energy and material flows into and out of the environment that are associated with producing a material, component, or assembly in the U.S.

Access the Database

The goals of the U.S. LCI Database project are:

  • Maintain data quality and transparency
  • Cover commonly used materials, products, and processes in the United States with up-to-date, critically reviewed LCI data
  • Support the expanded use of LCA as an environmental decision-making tool
  • Maintain compatibility with international LCI databases
  • Provide exceptional data accessibility
  • Be fully and sustainably supported
  • Support U.S. industry competitiveness.
