The data obtained from respondents was then tabulated and processed using Smart PLS 4.0. This study used validity and reliability tests to ensure the quality of the research instruments, as well as hypothesis testing to analyze the effect between variables based on respondent data. Findings-This study proves that green practices have a positive effect on green brand attachment and consumer-based green brand equity. Green brand attachment has a positive effect on consumer-based green brand equity. In addition, green brand attachment has also been proved as a partial mediator in the relationship between green practices and consumer-based green brand equity.

The implementation of these two things can contribute positively to consumer loyalty and equity.
