The online documentation for getenv:

getenv:
One arg VAR, a string.  Return the value of environment variable VAR,
as a string.


Neither the online documentation, nor the info file (version 1.03 of
the elisp manual), gives any hint to what happens if the environment
variable is undefined. It turns out that nil is returned. I think that
ought to be mentioned in the documentation.

Example: 
	  (getenv "UNDEFVAR")
	       => nil
