The PIE information system

The Platform on Integral Energy and emission projections (PIE) has been developed by the Netherlands Environmental Assessment Agency (MNP) and the Netherlands Energy Research Centre (ECN), two Dutch research centres with overlapping interests in the area of energy and emission projections. PIE has been set up to share data common to both centres and as a means of responding to policy questions with greater speed, flexibility and insight. This report first of all describes the history and purpose of PIE before providing an explanation of the conceptual model. This is followed by a discussion of the conceptual model's implementation in Excel and the mathematical rules connected with its use. The final chapter discusses plans for PIE application in the near future.
