There is a fair amount of research on green consumption and some research specifically focused on green seals of approval (hereafter referred to as green seals). For example, there are studies on the general communication effects of green seals (D’Souza et al., 2006; D’Souza et al., 2007), their appropriateness for specific product categories (Montoro-Rios et al., 2006; Montoro-Rios et al., 2008) and their origin, standards and classification (Horne, 2009).
