Going green can be as good for business as it is for the environment, especially if you spread the word about it. The key to successful green marketing campaigns is not to be too forceful; instead simply make potential customers aware of the tangible benefits of thinking environmentally, which they can do by frequenting your business. After all, the consumers your message will resonate with are the same ones who will want to buy from you because your beliefs mirror theirs. For the rest, your green marketing campaign will help them better understand the environmental issues at hand and how they apply to everybody.
