Regional energy and CO2 scenarios: a decision support tool for policy makers

The article describes methodological approach, data requirements and uncertainties of a modelling tool that allow to assess regional energy consumption and CO2 emissions, and to calculate energy- and CO2-projections until 2030. The model is calibrated to Swiss conditions. Regional data are derived by downscaling. However, the model gives users the possibility to adjust variables to their preferences to account for local specificities and/or to experiment with other than standard trend assumptions. The interface is fully graphical. The model is implemented on the Internet. Target users are national and regional policy makers and representatives from NGOs.
