ABSTRACT
The purpose of this paper is to reveal the relationships between consumers’ religiosity and their environmental attitudes. The study also tests the mediating role personal moral philosophies, idealism, and relativism have on this relationship. The data were obtained online from 541 consumers across Türkiye, and structural equation modeling was used to analyze the data. The results indicate no direct relationship to exist between religiosity and pro-environmental attitudes, while an indirect and positive relationship exists between them with idealism having a full mediating role and relativism having no mediating role. Moreover, a direct positive relationship exists between religiosity and environmental apathy, with idealism having a negative partial mediating effect and relativism having a positive partial mediating effect on this relationship. The results contribute theoretically to the literature on consumer ethical decision-making and practically to promoting pro-environmental behaviors in societies with relatively strong religious attitudes and in marketing managers by providing clues about the probable demand for green products and what is expected environmentally from businesses.
