About the LCI Database Project

The U.S. Life Cycle Inventory (LCI) Database is a publicly available database that allows users to objectively review and compare analysis results that are based on similar data collection and analysis methods.

Finding consistent and transparent LCI data for life cycle assessments (LCAs) is difficult. NREL works with LCA experts to solve this problem by providing a central source of critically reviewed LCI data through its LCI Database Project. NREL's High-Performance Buildings research group is working closely with government stakeholders, and industry partners to develop and maintain the database. The 2009 U.S. Life Cycle Inventory (LCI) Data Stakeholder meeting was an important step in the ongoing improvement of the database. Prior to that event, NREL conducted a poll of current and potential users of the LCI database to help guide meeting discussions and produce user feedback. Read more about the project's goals and findings from the 2009 Stakeholder Meeting in the U.S. Life Cycle Inventory Database Roadmap.

Initial Development

This LCI Database Project was initiated on May 1, 2001, and gained national prominence at a meeting of interests hosted by the Ford Motor Company. Funding agencies and representatives of industrial, academic, and consulting communities voiced strong support for the project. As a result, an advisory group with 45 representatives from manufacturing, government, and nongovernment organizations, as well as LCA experts, worked together to create the U.S. LCI Database Project Development Guidelines.


The U.S. LCI database is supported by a variety of different stakeholders. These stakeholders have actively participated in or funded some aspect of the database's development since its launch in 2001. For a list of project supporters and collaborators, read the stakeholders page.

Advisory Committee

The U.S. LCI Database has established an advisory committee to provide technical and financial advice and guidance the NREL database management team. Read more about the U.S. LCI Database on in the advisory committee section.
