Quantitative Assessment Method for Supporting Scenario Workshops toward Sustainable Consumption and Production

Sustainable consumption and production (SCP) is a key to envisioning the desirable linkage between consumers and producers for transforming the mass production paradigm. The authors have proposed a method for designing scenarios to describe visions and pathways for SCP. This paper proposes a method for quantifying scenarios using expert workshops to clarify effective SCP measures. That is, we develop a simplified model to help workshop participants execute iterative cycles of changing parameter values and evaluate the environmental effects of SCP measures. In a case study, a scenario for Vietnam was quantified to extract conditions for halving CO2 emissions in 2050.
