COOntrol Z is principally designed as an environmentally friendly e-commerce application. The idea comes from the fact that carbon emission rates have become one of the most important agenda items to consider across the world. The first point that differentiates this application from other e-commerce applications is the new technology provided, which will highlight the companies that cause less carbon footprint. Customers will also be encouraged to collect Green Coins and use them for buying more environmentally friendly products afterward. COOntrol Z aims to accomplish sustainable shopping and all necessary features will be designed considering the ways that reduce the carbon emission and overall harm to nature. In other words, it aims to motivate the companies and customers to be more sensitive about sustainability.
