Faith and Sustainability: Exploring Religiosity’s Impact on Intentions to Reduce Food Waste

This study investigates the influence of religiosity on environmental concern and intentions to reduce food waste in Islam and Christianity. The study involves 575 adult participants, predominantly Muslims and Christians, utilizing the Duke University Religion Index (DUREL) religiosity scale, environmental concern scale, and food waste reduction intention scale. The investigation was conducted in Romania, Italy, and Turkey. Utilizing structural equation modeling (SEM) via AMOS software, the research reveals that religiosity significantly affects environmental concern in both religious groups. Furthermore, environmental concern acts as a mediator between religiosity and both Muslim and Christian participants. Notably, the impact of religiosity on the intention to reduce food waste is significant among Muslims, but is not observed among Christians. The study underscores the importance of integrating religiosity into consumer behavior research, especially concerning food waste reduction. It suggests that religiosity and environmental concern are crucial for successful campaigns targeting food waste reduction among Muslim and Christian consumers.
