Despite the development of green products, convincing consumers to engage in green consumption is still a difficult task. This research attempts to help solve this problem from the perspective of brand logo design. Specifically, this research explores how circular and angular logo shapes influence green consumption. Three studies provide support for our basic prediction that a circular (vs. angular) logo is more effective in promoting green consumption. Self-construal plays a mediating role in this mechanism. However, the logo shape effect disappears when consumers are primed with high sense of power. When taken together, this research not only has theoretical contributions to green consumption and visual marketing, it also provides practical implications for firms manufacturing green products.
