The next big thing in sustainable product design is as sustainable alternatives become increasingly cheaper, new challenges and markets will arise as these products become a more significant part of people's lives. Rather than switching to a sustainable alternative, the situation for consumers will most likely become a question of which sustainable product to choose out of many other sustainable alternatives. How will large suppliers and department stores change their catalogs and physical stores in response? How does a rising strong sustainable competitive market act with e-commerce and customer behavior (logistics, sustainable transportation)?
