Sadly one can't use environment variables in file system uri's because the '%' is used for character encoding (eg space %20)
Maybe one day the IETF will devise a way to overcome that restriction, or MS will allow substitution of the '%envvarname%' convention by say a '$envvarname' convention. Although I'm not holding my breath on either.
You could write some javascript in the CSS. There's some VBA code somewhere that addresses the issue - I have seen it used in Excel macro's. Conversion of VBA to JS is doable.
