Eco-labeling can foster environmentally friendly consumer behavior and, in the aggregate, influenceand reduce environmental harm. In light of consumer interest and perceived economics gains for producers and retailers for making and selling a value-added product, eco-labels have proliferated. Despite the increase in green labels, there are concerns about consumer confusion and best practices, and there is limited information on the best process in creating an eco-label, what types of eco-labels are effective in changing consumer behavior, and how they should be designed. Our approach to eco-labeling is that a successful labeling should be rooted in the basic evolutionary psychological mechanisms underlying human decisions and behavior. Thus, development of eco-labeling strategies may benefit from exploration of evolutionary theories on human behavior. Based on this premise we analyse various aspects of eco-labeling and discuss what eco-label strategies anddesigns are expected to be successful and which may not be so.
