Life Cycle Assessment Harmonization
Download the Factsheet
The U.S. Department of Energy enlisted NREL to review and "harmonize" life cycle assessments (LCA) of electricity generation technologies. Hundreds of assessments have been published, often with considerable variability in results. These variations in approach, while usually legitimate, hamper comparison across studies and pooling of published results. Learn more about life cycle assessments of energy technologies.
By harmonizing this data, NREL seeks to reduce the uncertainty around estimates for environmental impacts of renewables and increase the value of the assessments to the policymaking and research communities.
NREL harmonizes this data in order to:
- Understand the range of published results of LCAs of electricity generation technologies
- Reduce the variability in published results
- Clarify the central tendency of published estimates.

NREL is planning to publish life cycle assessment harmonization results for natural gas. This research will be posted when it is available.
