Life Cycle Assessment Harmonization

Life cycle assessment (LCA) is a major thrust for sustainability analysis at NREL. Laboratory analysts are currently focusing on ways to "harmonize" LCA analysis and increase its value in the research community.

Analysts are also leveraging information from an existing LCA harmonization project. Their goal is to reduce the uncertainty around estimates for environmental impacts of renewables, and make the information useful to decision-makers in the near term.

NREL analysts have collected LCA literature, pared it down, and parsed it by technology. They are also extracting and statistically analyzing the information.

Environmental stressors being considered include:

  • Greenhouse gas emissions (initial focus)
  • Water
  • Fossil fuel use
  • Land-use
  • Energy balance
  • Major materials (e.g., steel, glass, concrete/cement, etc.)

In the end, one of the main objectives of this harmonization project will be creating consistent system boundaries.
