Climate change is currently identified as one of the most challenging global issues, which makes low-carbon development an increasingly popular topic that needs serious consideration. Therefore, the way cities are planned, managed, and use energy will play a vital role in mitigating climate change and its impact on the environment. Some simple city facilities such as pedestrian walkways, safe bikeways, and different modes of transportations, as well as sustainable policies and action programs, could reduce automobile dependency and greenhouse gas (GHG) emission in many cities. This project will explore such sufficient and practical rules and policies to redesign neighborhoods to create more sustainable, livable, and low-carbon cities, which will be accessible and attractive for all groups of people. This study reviews, compares, and analyzes different sustainable urbanism principles under three pillars of the sustainable development concept, including environmental, economical, and social. It also analyzes similar successful projects in Europe to find the appropriate and practical rules that are compatible with community requirements. The results show that all the sustainable principles should work together to create a sustainable community with reduced greenhouse gas emissions. Therefore, it is everyone’s responsibility to care about the future. It is necessary for urban planners, architects, and any related divisions of government to follow the proper rules to make cities a better place to live and also to increase residents’ awareness of both climate change issues and practical solutions. Urban planners are responsible for inviting people to be involved in making decisions and sharing their ideas to enrich communication, with the purpose of making a better city to live in.
