Present article gives continuity to the elaboration of the infotercio financial model proposed as an alternative to implementing environmental management systems in governmental institutions based on the emission reduction of printed reports, source codes and forms originated from IT activities. It discusses procedures of green IT certification for managers and governmental institutions derived from ISO 14000 family and People CMM, combining both in a new set of requirements. Also it summarizes the reasons for such a certification system, noting that waste paper is now a major global problem, not only in terms of direct environmental impacts but from the point of view of the unreasonable and unnecessary use of paper in governmental business processes, generating high costs, mismanagements and time losses, at the same time causing reduction in the available physical space in corporate environments and increase in fuel consumption for transport.
