In order to develop environmental long-term goals with respect to glocal climate change an index to compare the tempreature increasing effect of greenhouse gas emissions is neede. In this report for the most important greenhouse gases CO2, CH4, N2O, CFC-11 and CFC-12 the concept of Temperature Increasing Potential (TIP) is introduced as a greenhouse pendant to the ozone depleting potential (ODP). To obtain the relationship between an emission and its associated effect on temperature both model approach and analytical approach is used. In determing the TEP with help of models, IMAGE (the Integrated Model for the Assessment of the Greenhouse Effect) is used. The analytical method to obtain TIP values involves a direct way (from emissions to global temperature increase) and a indirect way (from emissions via concentrations to global temperature increase). Finally both methods are compared to previous efforts to determine relative greenhouse gas potentials.
