Climate change and sustainable city

Climate change is not just a problem of technology, society, economy, or governance. All of these actions must be significantly altered to address climate change. The huge decarbonization challenge is predicted to have a considerable impact on cities and metropolitan areas. The success or failure of the decarbonization transitions required to prevent severe effects from climate change will be determined by our choices and actions in respect to climate change mitigation and adaptation.

Elements of a sustainable city

Sustainable cities are knowledge-based cities that require efficiency in every aspect of their infrastructure. Energy efficiency is a key sustainability principle that must be embedded in a sustainable city in order to eliminate wasteful energy wastes. A sustainable city must also have a reliable, economical, emission-free, and affordable transportation system. Human and environmental health, traditional culture, social fairness, and social amenities are just a few of the numerous requirements that a sustainable building must meet. One of the main goals of sustainability is lowering the amount of energy used in buildings. Additional sustainability principles in sustainable cities include waste and food management, resource management using earth's rich resources, and finally, accommodating population expansion.

Resilience and sustainable city

The world has experienced many pandemics over the past century, not just the most recent COVID-19. There are chances for future pandemics, natural disasters (floods, earth quakes, hurricanes etc.), and human-caused disruptions. Disasters affect people more frequently in urban areas. For instance, metropolitan regions have been reported to have 95% of the COVID-19 cases . The pandemic has been a catalyst for ensuring resilience in sustainable cities . There is a need to create sustainable cities that are robust to natural calamities and problems caused by humans while still being economically and environmentally sound. Four interconnected sectors, including the economy, environment, governance, and society, are what make cities resilient. Co-creation and citizen engagement are also seen as crucial to creating resilience in cities. Persistence, modularity, redundancy, memory, robustness, resiliency, and transformability are qualities that are specific to resilient cities and help them adapt.

City climate action plan

The urgency and magnitude of the climate crisis should be reflected in the climate action plan. Local mitigation goals should support the overall national emission reduction aim in order to help prevent catastrophic levels of global warming. While some cities are creating independent, multi-sector plans that are especially geared towards combating climate change, others are integrating the issue into ongoing public planning procedures. Both methods of a city-level climate action plan are supported by the current guiding principles.
