Green Job Vacancies at the United Nations

Just the other day I found a good site that lists job vacancies in the United Nations Environment Programme.  The site can be viewed at www.unep.org/vacancies.  The site for the home page of the UN Environment Programme is http://www.unep.org/.  EarthDirectory's directory of UN agencies that are involved with environmental issues can be seen at www.earthdirectory.net/UN.  You can check the "jobs", "employment" or "vacancies" sections of the individual agencies for their available jobs.
