Many challenges are associated with the increasing level of energyconsumption and the environ- mental damage caused. At the locallevel, there is noise and air pollution while at the global levelthere are problems associated with acid rain, ozone layer depletionand the greenhouse effects. The transport sector is a majorcontributor in both cases. The use of appropriate decision-makingtools is required to assist in asses- sing alternative transportpolicies. One such tool is the Total Emissions Model for IntegratedSystems (TEMIS) program, developed at the Institute of AppliedEcology, Darmstadt.
