Green incentives on digital payment platforms act as key behavioral tools to steer consumer sustainable decisions. Using a motivational

opportunity

and capability framework

this study analyzes how common incentives (like green points and carbon footprint visualization) function. It aims to clarify the internal process that translates these external prompts into pro-environmental behavior. Current mechanisms

however

face practical limits. Users often experience "behavioral fatigue" as incentives show diminishing returns. A lack of clarity in environmental benefit transmission can decouple the feedback loop. Moreover

short-term stimuli often fail to foster lasting value recognition. To address these issues

we propose optimization pathways: hierarchical dynamic incentive design

visual environmental benefit feedback chains

and value internalization cultivation systems. These solutions provide theoretical paradigms and practical references for platforms aiming to build long-term guidance mechanisms for sustainable ecological behavior.
