How to stimulate environmentally friendly consumption: Evidence from a nationwide social experiment in Japan to promote eco-friendly coffee

摘要

We investigate the effect of information provision about environmentally friendly coffee on consumers' purchasing behaviors. We use a dataset from a nationwide social experiment in Japan involving over 10,000 vending machines serving brewed coffee. We also provide empirical insights into the potential drivers affecting proenvironmental behavior of consumers through information provision. Our results demonstrate that informing consumers about the product's eco-friendliness significantly increases eco-friendly coffee sales (+7%) only in social spaces (e.g., office buildings) and not in non-social spaces (e.g., shopping malls). Consumers in social spaces might be motivated to purchase eco-friendly coffee to build a "green" reputation among community members after receiving such information.
