Effects of brand knowledge on green trust and green brand equity: multigroup comparisons based on perceived brand greenness and age

Abstract

Purpose

The purpose of this study is to understand how consumers' green trust and green brand equity (GBE) vary by perceived brand greenness and age in the US market from the lens of brand knowledge (brand awareness and brand image).

Design/methodology/approach

Three multiple-group comparisons of structural equation modeling were used to analyze the data collected from a questionnaire. An experimental design was applied (high vs. low perceived brand greenness). A total of 440 usable responses were collected from an online consumer panel. With a higher percentage of participants older than 60 years, two groups were used, younger (under 55) and older (over 55), within each brand condition to conduct age comparisons.

Findings

Consumers' previous brand experience is important. The most promising indicators are brand image and green trust for GBE. A difference was observed between the group comparisons. For the less perceived green brand, existing brand image played a more important role in the process, and there is a need to enhance its green trust. For the higher perceived green brand, more factors should be included to explain their GBE, especially for consumers under 55.

Originality

This study identified two moderators, perceived brand greenness and age, in the formation of GBE, which has not been widely explored in the literature. The findings provide significant insights for generational cohorts, focusing for the first time on the joint catalyst effect of greenness and age regarding the influence of GBE on consumers' commitment to green brands. Additionally, the fact that a higher percentage of participants are Baby Boomers enables this study to add to the existing body of literature and bring unique perspectives to understand their and their younger counterparts' attitude toward green consumption.
