Sustainable companies exist in every market segment: whether food or textile, household goods or building materials, financial service providers or energy providers. Sustainable companies stand for ecologically and socially just products and thus make a valuable contribution to the sustainable consumption every single one. The fact that sustainable companies are becoming increasingly popular is also shown by various market surveys. More and more pioneers and start-ups are focusing on sustainability, because demand is constantly increasing and so is the supply. And the products of sustainable companies are no longer a niche. They have become mass suitable and can be found in the supermarket as well as in drugstores and the like. Who buys consciously, knows that the variety of sustainable enterprises is great.
