The newly developed green fashion product, Eco-friendly Faux Leather Apparel (E-FLA) helps minimize harmful environmental impact with a low carbon footprint utilizing the progression of Bio-based Polyurethane and Nanocellulose technique. This study investigates green product purchase intentions along with the best available socio-psychological determinants and product criteria of the consumer green product adoption that can assist to launch E-FLA products in both western (England and the US) and eastern (China and South Korea) marketplaces. A total of 1,202 female respondents between the ages of 20 and 50 from England (N=297), the US (N=305), China (N=300), and Korea (N=300) completed the online survey. ANOVA indicated significant difference in consumers’ socio-psychological characteristics (consumption values, ethical consumption beliefs, self-satisfaction of ethical consumption, perceived consumer effectiveness, and environmental knowledge) and product criteria (product attributes of E-FLA) across four countries. Purchase intention and willingness to pay a premium for E-FLA products were shown differently across four countries. Multiple regression analysis results demonstrated differences in consumers’ socio-psychological and product criteria determinants for the purchase intention of E-FLA products across countries. Evidence suggests that differentiated marketing strategies for E-FLA products are required when targeting global consumers. Practical implications and theoretical suggestions to understand consumer sustainable consumption attitudes are proposed.
