Green technology products are playing an increasingly vital role in sustainable consumption and the advancement of a green economy. Nevertheless, green technology consumption in Vietnam has not yet become as widespread as anticipated. This study seeks to identify and measure the extent to which product quality factors influence Vietnamese consumers’ behavior toward green technology products. A quantitative approach was employed with a sample of 350 respondents, selected through purposive non-probability sampling, to survey users of green technology products in Vietnam. The findings reveal that product performance, reliability, friendliness, and green certification exert significant positive influences on consumer behavior. These results provide valuable implications for businesses in enhancing product development strategies and for policymakers in promoting sustainable consumption practices
