I once did a calculation for my very cost conscious airline. I took and average intra EU flight and counted the number of pages of NOTAMS & WX we had to print out before flight. (there was no chance to digest the NOTAMS in preflight, if you turned up on time.) I measured the thickness. I then multiplied that by the number on annual flights the company made and weight of unnecessary paper that was thrown away each year. The height of the column of paper was astronomical; the cost of paper & toner was huge, and the waste of time distracting. The environment affect was colossal. No reply. I had tried and gave up.
