There technically is an incentive, though it might not be recognized as being enough to move the needle (mentioned later): if pollution is not taken care of in some way, the costs associated with supplying (producing) some thing (good or service) or things is likely increased as a result of the pollution.
The incentive to care about pollution, then, is the potential to save money when producing some thing or things by reducing the levels of pollution. That is, if it would cost less money to reduce pollution than the pollution causes the costs of production to increase, then you have an opportunity to save money by reducing pollution and possibly an opportunity to produce more (incentive to reduce pollution).
Problem is, the incentive might not be recognized as being enough to move the needle because the increase in costs of producing is likely distributed across many producers and its effect might be too minimal on a per-producer basis for them to either recognize that it exists or too costly to do anything at the level that they experience its effects.
