Baseline/reference The state against which change is measured. In the context of transformation pathways, the term ‘baseline scenarios’ refers to scenarios that are based on the assumption that no mitigation policies or measures will be implemented beyond those that are already in force and/or are legislated or planned to be adopted. Baseline scenarios are not intended to be predictions of the future, but rather counterfactual constructions that can serve to highlight the level of emissions that would occur without further policy effort. Typically, baseline scenarios are then compared to mitigation scenarios that are constructed to meet different goals for greenhouse gas emissions, atmospheric concentrations or temperature change. The term ‘baseline scenario’ is used interchangeably with ‘reference scenario’ and ‘no policy scen
