Retailers can choose to sell products that are made from natural and renewable resources, are non-toxic and have a minimal impact on the environment. They can also choose to operate their stores in an environmentally friendly manner by using renewable energy sources, recycling and reducing waste, and promoting energy efficiency. By doing so, retailers can help reduce their environmental impact and promote a healthier indoor environment for their customers and employees.
