The present study, in order to predict the behavioral intention and action of consumers for green technology products and eco-friendly certified products, has set up the attitude, subjective norm, and perceived behavioral control as preemptive factors based on the planned behavioral theory; and verified the effect on the behavioral intention and action empirically through a model analysis by the structural equation. The objective of the present study is a consumer who has purchased all products of green technology products and eco-friendly certification and who has experienced of using them. The survey was conducted online, and a total sample of 300 people was collected. Statistical analysis was conducted through structural equation model analysis using the SmartPLS program, and the results of the analysis are summarized as follows. (1) Products of green technology: The attitude, subjective norm and perceived behavioral control of consumers has shown a significant positive effect (+) on the behavioral intention statistically. Especially, it has been confirmed that the attitude (β=0.353) caused the greatest effect on the behavioral intention. It has shown that statistically the behavioral intention caused a significant positive effect (+) on the behavior. (2) Eco-friendly certified product: It has shown that the attitude, subjective norm, and perceived behavioral control of consumers caused a significant positive effect (+) on the behavioral intention statistically. Especially, it has been confirmed that the subjective norm (β=0.385) caused the greatest effect on the behavioral intention. And it has shown that the behavioral intention caused a significant positive effect (+) on the behavior statistically. The present study suggests that consumer purchases must take precedence in order to establish a system for green technology products and eco-friendly certification products promoted by the government for carbon neutrality. Education and promotions that can change consumer awareness of green technology products and eco-friendly certified products must be promoted.
