Reduce margins and save paper

In my quest for new ideas I've stumbled across one that's been thought of before.

Reduce the margins in Word documents and save money (and the planet) http://www.bio.psu.edu/greendestiny/publications/1.pdf
I tested this on a 36 page document where I am working at a leading high street retailer. By reducing the left and right margins by 1cm each it saved one page (2.8%)

Reduce the font size by one point (in Word use the shortcut CTRL + A, CTRL + [ ). This saved another three pages (a further 8.3%)

Luckily the high street retailer in this example already enforces duplex printing (that's a 50% saving that is already there). Challenge any company not using duplex! The cost of a duplex printer over a simplex (!) printer is far less than half their paper bill each year - non-duplex printers should be banned from the workplace.

Played around with trimming down the header and footer so that they take no more than a horizontal rule and a single line of text. Also reduced the top and bottom margin. That didn't effect my 36 page document

..OMG...replacing all the manual page breaks (you can search and replace them in Word click on Edit > Replace... > More > Special or search for ^m) and removing the automatic page breaks on the Heading 1 style saved another 9 pages (a further 25%)

Then removing all spare lines (repeatedly search for ^p^p^p and replace with ^p^p) shed another couple of pages (a further 5.5%)

What about title pages? Most of the document I produce are less than 30 pages (or should be with the tricks above). Why waste an entire page on the title. I don't know how many documents we produce here but saving half to one page on every one must be worth something. In the case of the test above it's another 1% or so.

The verdict, these tricks saved nearly 40% on the number of pages. With duplex printing here that is 20% of the paper on every copy printed. Given that this document will go through several versions and there are three or four people who will review it this could amount to...5 versions x 4 reviewers x 4 pages = 80 sheets of paper. 1 ream of paper is 500 sheets at ~£3 a ream = saved 48p

Perhaps this leading retailer might consider paying me half the profit for telling them about it.
