This paper examines how marketing has been used as a tool to promote awareness among consumers about environmental issues and to encourage them to make sustainable choices. Marketing campaigns have been instrumental in the widespread adoption of sustainable practices such as recycling, second-hand shopping, and reducing personal waste. As consumers become more conscious of their choices, companies use green marketing to capitalize on these social trends. While many companies do have the intent to sell a truly sustainable product to fulfill customer needs, others simply use the label to profit, without putting forth a sustainable product. This practice is referred to as “greenwashing.” The Federal Trade Commission (FTC) has put forth regulatory guidelines to combat this issue, but does not seem to have the necessary resources to penalize companies who do not follow the regulations. In fact, there are many guidelines that are optional for companies to follow, but not mandatory, making it difficult to spot false claims. We conducted two surveys of over 300 college students to assess their perceptions of sustainability and how it influences their everyday choices. We asked questions about perceived sustainability of various brands, some of which with known sustainability campaigns, and others without. We found that many students hold similar perceptions of sustainability and saw interesting trends in how sustainability affects their day-to-day purchase habits.
