Okoupon is an application that tracks how sustainable your shopping behaviour is and rewards your good behaviour with money back against a future purchase. Tracking information from supermarket supply chain APIs, users can have a clearer idea on how much wasteful packaging, logistical emissions and carbon impact every product they buy can have. Consumers can scan their reciept for an itemised breakdown and have their last transactions track how green each item really is. Retailers will benefit from environmental tax incentives and some of these savings can be passed on directly to the conumers who are helping to drive twoards a more sustainable and less wasteful future.
