Although China has enjoyed great economic growth in the past several years, environmental problems have not attracted enough attention, especially for the young Chinese population (Generation Z consumers). Based on the theory of planned behavior, this work aims to analyze the mediation role of product attributes, perceived consumer effectiveness (PCE), and environmental awareness in eco-label–informed purchase for Gen Z consumers in China. According to the result, it shows (a) eco-label–informed purchase could significantly increase two threads of PCE and product attributes, (b) those two threads intermediate the eco-labeling and environmental awareness positively, and (c) eventually lead to purchase behavior for Chinese Generation Z. For theoretical contribution, this article tries to have a more comprehensive investigation on green consumption, and to explore the theoretical relationship among product attributes, PCE, and environmental awareness in the context of Chinese Gen Z. Relevant managerial implications and practical guides are also discussed in this article.
