The concept of life cycle thinking (LCT) is essential for sustainable consumption and product development. A thorough evaluation of its impacts on people’s environmental consciousness and behavior is still lacking, however, as is people’s understanding of the LCT concept. The present study aims to evaluate the effect of LCT on people’s attitudes and behaviors, using an information-provision strategy, and to compare the effects of LCT-based information with other types of information provision. LCT-based and alternative information were created for promoting two pro-environmental behaviors: waste separation and refill product purchase. Designed information was distributed through a web-based survey conducted in Bangkok, Thailand and its vicinity. The LCT-based information about both waste separation and refill products had significant impacts on improving the respondents’ attitudes toward the target behaviors, but its effects on behavior improvement in both cases were insignificant. Compared with the alternative information provided, the LCT-based information was significantly more useful in relation to both target behaviors. The results of the present study suggest the possibility and opportunity for using the LCT concept for both promotion of and education on sustainable consumption.
