Consumer knowledge in pro-environmental behavior An exploration of its antecedents and consequences

Purpose - Environmental behavior studies suggest that knowledge, in addition to other psychological and social factors, can play an important role in consumers' environmental behavior change. The purpose of this paper is to understand the relationship between knowledge and various psychological factors which encourage consumers' participation in pro-environmental behaviors. The relationships that link an individual's attitudes toward science, environmental values, different types of knowledge (i.e. scientific facts, environmental facts, and subjective environmental knowledge), environmental risk perception, and willingness to pay (WTP) for the environment with pro-environmental behavior were examined. Design/methodology/approach - Theoretically guided hypotheses and model were formulated and tested with multiple linear regression models. The study was based on measures and data obtained from the large-sample secondary database of the 2010 General Social Survey (n = 2,044). Findings - Results indicated that while attitudes toward science had direct effects on knowledge of scientific facts and knowledge of environmental facts, environmental values showed effects on knowledge of environmental facts and subjective knowledge on environmental issues. The results also indicated that from different types of knowledge, subjective knowledge on environmental issues had effects on both environmental risk perception and WTP for the environment. Knowledge on environmental facts, on the other hand, was able to predict only environmental risk perception. The scientific factual knowledge did not show an effect on mediator of pro-environmental behavior. Also, subjective knowledge indicated indirect effects on pro-environmental behavior through environmental risk perception and WTP for the environment. Originality/value - Although research on understanding factors influencing pro-environmental behaviors and potential relations to individual knowledge has grown in recent years, there has been very little attempt at distinguishing between different types of knowledge and investigating their potential roles in the context of environmentally relevant behaviors. This study will help understand the functioning of different types of consumer environmental knowledge and their impacts on pro-environmental behaviors more in depth.
