Issue Environment Friendly Training Notes

A method to decrease the paper waste.

Steps

Beware that many companies will request print-outs of the training notes to be given to the attendants.
Note that the page design is critical, directly affecting the number of pages.
Keep in mind that handouts with big blanks on each page is a common practice everywhere (if this area is excessive for the related topic, then it becomes a waste of paper)
Try an alternative approach :
Use compact page design
Distribute blank paper to attendants to take notes if necessary
Send electronic copies of the notes (for e.g. secured pdf copy) to the attendants in advance (suggesting that interested participants can attend with laptops and use electronic copy instead of printed copies).
