The main aim of this conference proceedings book is to provide a platform for researchers, and academics from around the world to engage in discussions and share their research findings and insights regarding sustainability, net-zero initiatives, circular economy solutions, and strategies for building resilient cities and communities. The primary focus is to explore the potential of transitioning to a circular economy while simultaneously working towards net-zero emissions and enhancing the resilience of urban areas. In the context of this conference, the circular economy is regarded as a crucial mechanism for reducing emissions. It accomplishes this by promoting the use of renewable resources, minimizing waste and pollution, and cultivating sustainable consumption and production practices. On the other hand, net-zero solutions play a vital role in expediting the shift to a circular economy by facilitating the adoption of clean and cost-effective energy sources, decreasing the carbon footprint of various production processes, enabling the utilization of carbon capture and storage technologies, and ultimately fostering the development of resilient cities where people can live and work in an environmentally friendly manner
