There are many possible sources for life cycle assessment data. This page lists useful direct sources of data, as well as some lists of databases, that may be helpful to those conducting life cycle assessments (LCAs).
The list is not comprehensive, as there are many possible sources of the kind of data necessary to conduct LCAs, but it should be helpful in getting started. It is also in no particular order. If you would like to recommend a source to be added to this page, please contact us.
Emissions and Energy Data
- U.S. Environmental Protection Agency Emissions & Generation Resource Integrated Database (eGRID)
- Electricity emissions and power generation mix for various regions and states in the U.S. There is also an interactive graphical interface from the EPA that presents eGRID data. Data in these resources only represents emissions from power plants in the regions and not from upstream fuel or material extraction and processing
- U.S. Environmental Protection Agency Waste Reduction Model (WARM)
- Emissions from end-of-life pathways for various materials
- U.S. Argonne National Laboratory Greenhouse gases, Regulated Emissions, and Energy use in Technologies Model (GREET)
- Energy use and emissions from various vehicle, fuel, and material combinations. Offers both Excel and graphical interface options along with related tools and models
- GHGenius
