Will rebound behaviour diminish the decarbonization potential of carbon generalized system of preferences in China?

Abstract

The Carbon Generalized System of Preferences (CGSP) is an innovative mechanism aimed at mitigating personal carbon emissions through changes in consumer behaviour. Given that changes in consumer behaviour can lead to released expenditure and subsequent rebound behaviour, while the potential impact of rebound behaviour on decarbonization effect of CGSP remains unclear. This study extends the LCA-EEIO model to assess the decarbonization potential of 27 green actions (e.g., Clothes repair, Food sufficient, Less flying, etc.) within 5 low-carbon strategies (Clothes, Food, Shelter, Transport, and Others). Our findings reveal that each green action results in carbon emissions reductions, with Natural fibers demonstrating the most favorable outcomes. Notably, the study also reveals that rebound behaviour has a detrimental impact on the decarbonization potential of CGSP, potentially undermining the effectiveness of certain green actions (i.e., Work from home, Repair equipment). Additionally, the research uncovered negative interaction effects among green actions, further diminishing the decarbonization potential of CGSP. These findings provide valuable insights for policymakers in designing an effective CGSP aimed at reducing personal carbon emissions in developing countries.
