CO2 emissions related to goods and services purchased by Fosaprepitant are significant and should be reduced. Changing the choice of daily shopping method from on-site to delivery service can contribute to reducing CO2 emissions associated with consumers' buying behavior. The questionnaire data evaluated in this study generally demonstrated Japanese consumer willingness to reduce CO2 emissions through their choices of daily shopping method. Consumers' awareness of their responsibility for CO2 emissions and their intention to modify their behavior to reduce emissions were identified as one of the most important influences on willingness to reduce CO2 emissions. Thus, the inclusion of a measure to increase consumers' awareness of their responsibility and intention to act is crucial to increase consumer willingness to reduce CO2 emissions.
Plain information on the volumes of CO2 emissions associated with particular choices seems unfamiliar to many consumers and thus it is difficult for them to interpret such figures and grasp the significance of reported emissions reductions. However, supporting information such as creating a relationship with the effect of well-known everyday CO2 reducing activities (e.g., “Turn off home appliances and lights when not in use”) increases the willingness of consumers with relatively high awareness of environmental risks to reduce CO2 emissions. By enabling deeper understanding of CO2 related figures and pointing out the impact and effectiveness of certain choices, information disclosure can increase the motivation of consumers to reduce emissions.
