The Internet of Things (IoT) revolution drives innovation in numerous fields of research and daily life by enabling anytime, everywhere access to data in fresh contexts. Through this innovation, there have been previously unheard-of connections between people, objects, places, organisations, and facilities. Despite the many advantages of IoT products and systems, creating, distributing, and using them requires a lot of energy and resources and is accompanied by rising amounts of solid and toxic waste. It is essential to effectively address issues like rising energy consumption, waste, and greenhouse gas emissions if we are to ensure that the potential adverse impacts of technological growth are kept to a minimum. For this reason, we are heading towards a more environmentally friendly future in which green technology, green IoT, and green economies will, respectively, replace current technology, IoT, and economies. This implies that there will be a vast array of potential enhancements to human welfare, which contribute to the development of a sustainable, intelligent world. This study examines the principles and functions of G-IoT in the advancement of society by examining its potential to enhance quality of life, the environment, economic growth, and green global modernization. It also analyses the significance of greening technologies processes in sustainable development. It has been demonstrated that the G-IoT has the ability to revolutionize and bring about a variety of benefits in various industries using the most recent technological approaches and solutions, while also eradicating or greatly reducing the detrimental effects on the well-being of humans and the environment.
