Although sustainability is not something that is only important in online retail, it is something that companies can show more easily online than you would in a traditional brick and mortar store. If your company has sustainability practices, call them out online! Work it into your copy, make sure it’s in your key features, and create infographics or videos to educate customers on what you are doing. Sustainability is important to consumers, and they will remember it forever. Also, if you are selling on Walmart or Amazon, there are places where sustainable brands can be featured. If you can get your items approved for sustainability, your items will get free placement onsite and in stores where people are actively looking for sustainable brands to support.
