ABSTRACT
Environmental consciousness is linked to pro-environmental consumption behavior;however, the consequences of variations in the level of environmental consciousness have not been fully investigated. Therefore, we evaluated differences in individualism, collectivism, materialism, willingness to pay (WTP) for environmental protection, and pro-environmental consumption between groups with varying levels of environmental consciousness. After evaluating the factors that differentiate these groups, we identified the determinants of pro-environmental consumption for each group. For the study, an online survey was conducted, including 472 adults aged 20–69 years. Groups with low and high levels of environmental consciousness differed significantly with respect to all factors except individualism. The group with a high environmental consciousness exhibited higher collectivism, WTP for environmental protection, and pro-environmental consumption behavior, and lower materialism than the group with a low environmental consciousness. For the group with low environmental consciousness, collectivism was the main factor affecting pro-environmental consumption behavior (i.e., purchase, use, and disposal). In the group with high environmental consciousness, WTP for environmental protection and collectivism were the main determinants of pro-environmental consumption behavior. These results provide a basis for a systematic approach to improve pro-environmental consumption behavior based on environmental consciousness.
