“Cause marketing campaigns,” or “commercial co-ventures” (i.e., advertising campaigns in which a company indicates that the purchase or use of its products will result in a charitable contribution) have long been a popular fundraising tool for charities. Some state charity authorities regulate cause marketing campaigns with a variety of requirements; some states do not regulate the practice. While such campaigns have grown into a billion-dollar-a-year industry, the perception is that they often fail to provide consumers with sufficient information to enable them to understand how their purchases will actually benefit charity. New York Attorney General Eric T. Schneiderman recently issued a set of best practices, entitled “Five Best Practices for Transparent Cause Marketing,” which are designed to promote transparency in cause marketing campaigns. These were developed in and for the state of New York but, as described below, we can expect other states to consider and possibly adopt these best practices as well.
