Environmental Life Cycle Assessment (LCA) Learning Module Series

Welcome to the LCA Learning Module Series.

This is a series of LCA learning modules in PowerPoint. The modules will be uploaded as they are developed or updated. They are intended to be used for personal education, short background workshops or as components for more detailed classes.

The following is a listing of the groups that the different modules will be placed in.

As can be seen by the listing some of the modules are for more general knowledge (overview modules), while some are more detailed.

  • Group A: ISO Compliant LCA Overview Modules
  • Group α: ISO Compliant LCA Detailed Modules
  • Group B: Environmental Impact Categories Overview Modules
  • Group β: Environmental Impact Categories Detailed Modules
  • Group G: General LCA Tools Overview Modules
  • Group γ: General LCA Tools Detailed Modules
  • Group T: Transportation-Related LCA Overview Modules
  • Group τ: Transportation-Related LCA Detailed Modules

The following are the modules currently available and links to them:

Directions for Use

  • The modules are in PowerPoint format with narration and will automatically play the audio and advance slides when put in presentation mode.
  • One can pause by leaving presentation mode (press esc, or right click and pause or end show) and re-enter at the start of any slide.
  • Overview modules contain a self-assessment quiz at the end of the presentation that you can optionally take at your own pace by forwarding the slides. Correct answers are provided.
  • Detailed modules provide a few suggestions for homework or further study at the end of the slideshow.
  • If audio is playing before opening the file or playing over the top of the presentation, you may have the preview pane turned on in Windows. If you disable the preview pane this issue will be corrected, or you can simply start the slide show, wait for the first audio bit to complete, and the presentation will continue correctly.
