Climate protection scenarios are an important basis for long-term climate protection planning. The modelling, which is often carried out in extensive studies, is a central source of information for decision makers and stakeholders in the development of climate protection strategies. This report outlines a catalog of criteria for the systematic evaluation of long-term climate protection scenarios.  The criteria were selected on the basis of four guiding questions relating to the degree of reduction envisaged, the way in which this reduction is achieved, the contextual conditions and the methodological strength of the underlying modeling.
