NIMBY (“not in my backyard”) problems involve a contradiction in which people recognize that facilities contribute to the public interest, but oppose the construction of such facilities near their homes. The construction of high-level radioactive waste (HLW) disposal facilities is a typical example of a NIMBY issue. This study aims to investigate the effects of procedural fairness on acceptance of NIMBY facilities by using the Elaboration Likelihood Model (ELM). An online scenario-based experiment was conducted regarding acceptance of HLW disposal facilities versus that of industrial waste disposal facilities (N = 373). ANOVA results suggested that procedural fairness increases acceptance of both nuclear-related and other facilities. Furthermore, hierarchical multiple regression analyses showed signifi cant interaction between perceived risk of NIMBY facilities and interest in those facilities. Our results suggest that ELM can be applied to investigate acceptance of NIMBY facilities.
