Although marketers are increasingly developing strategies to promote environmentally-friendly images for their brands, little is known about green brand architecture strategies. The current study examines two sub-branding strategies and finds that when green products are dispersed across several sub-brands (vs. concentrated within one sub-brand), consumers are more likely to infer that the overall parent brand is environmentally friendly. The sincerity of the company’s sustainability efforts is found to mediate the effects of the sub-branding strategy on consumers’ eco-friendly beliefs of the parent brand. Specifically, consumers associate dispersed strategy (vs. concentrated strategy) with intrinsic motive (vs. extrinsic motive) of the company’s sustainability policy. As a result, dispersed strategy instead of concentrated strategy promotes spillover effects of sustainability to the parent brand, demonstrating the impact of brand structure on spillover to the parent brand equity. Managerial implications are discussed related to the automobile company’s sub-branding strategy.
