We study how the supply of environmentalism, which is defi…ned by psychic benefi…ts (costs) associated with the purchase of high-environmental (low-environmental) qualities, affects the way …firms choose their products and the ensuing consequences for the global level of pollution. Contrary to general belief, a high supply of environmentalism does not give rise to a better environmental outcome because it endows fi…rms with more market power which they use to maximize profi…ts. By contrast, standard policy instruments such as a minimum quality standard or the use of greener technologies leads to a better ecological footprint.
