A Review on Blockchain Based Reward System for Sustainability (Greenstride)

Innovation by smart cities is supposed to adopt novel technologies and strategies in order to accelerate already existing sustainability solutions targeted for the fight against greenhouse gas emissions and climate change. We therefore overview the existing work concerning blockchain technologies and other digital technologies, including IoT with the purpose of incentivizing individuals and organizations towards more sustainable behaviors. Our attention is directed towards three principal domains in which digital technologies could catalyze initiatives aimed at reducing environmental repercussions: specif- ically, low-carbon transportation, energy efficiency, and waste diversion. Notable instances of such initiatives comprise The Plastic Bank, ECO-Coin, and SolarCoin. An examination of these case studies, wherein both financial and non-financial incentives have effectively facilitated changes in behavior, enables us to identify essential components necessary for the execution of blockchain-based solutions. We further outline critical pathways for further investigation in this area.
