United Nations' policy regarding Free Software?

[Bernhard Reiter]

Does the United Nations organization have a policy regarding Free Software
and its mission? And how does this affect the 17 specialisted  UN 
organisations?

Does the UN prefer to use and republish improvements with Free Software?

I found a general statement of the Secretary General's speech from 2010:

And some documentation from the UNESCO:
http://unesdoc.unesco.org/images/0021/002156/215621e.pdf

A lot of old links from the UNESCO portal of Free Software seem old.
Does somebody know more?

Thanks,
Bernhard
