Informing and marketing to your consumers why your cause or product is benefiting the environment, while trying to educate them on the subject.
A lot of people have positive emotional and political connections with environmentalism, so if your product is in favour of what the consumer supports. People will want to support your company, because your company supports that good cause. Customers will pay more money for your product, if it's going towards saving the environment. Ex: A 4$ water bottle made from recyclable materials. More and more people are purchasing organic foods to eat healthier and to support their community. This food is better for the environment because it's being made at a farm or bakery, not a factory.
