RESOURCES 14: LCIA and allocation
This module is designed to assist you and your team complete the LCA project. First I have posted the GREET LCA spreadsheet where you can find data for your LCIA. You will also find a few video resources with examples. The first video provides an overview of the concept of allocation. The second video is an ~30 min lecture that focuses on the LCIA. Remember that for your project is ok to focus on only one impact category, Prof. Kumar focuses in Global Warming Potential (GWP) in CO2eq per functional unit. Note that if your CO2 feedstock comes from biogenic resources, this receives a factor of zero. If region is an important factor in your particular LCA, explore the Webinar: Introducing Regionalized LCIA in OpenLCA 1.5.

- Allocation
- Watch the video to learn about allocation, one of steps in Life cycle inventory (LCI) which is the second phase in Life Cycle Assessment (LCA).

- Lecture: LCIA
- In this lecture, Prof. Kumar walks you thru an example LCIA of an incandescent light bulb. He first lists an inventory, then the factors (that you will find a database) and finally everything is converted to CO2 eq. for the impact category of Global Warming Potential (GWP). Note that normalization may be needed.
- Webinar: Introducing Regionalized LCIA in OpenLCA 1.5
- This webinar serves to introduce the new regionalized LCIA features included in openLCA 1.5. It includes explanations on how to add KML data to the inventory locations, create regionalized LCIA method using shapefile parameters, perform a fully regionalized LCIA calculation and analyse the results.
