What is meant by a sustainable city?

A sustainable city is defined as one that is designed to minimize environmental impact while providing a high quality of life for its residents. This concept encompasses various aspects of urban planning and development that prioritize environmental sustainability, social equity, and economic health. In a sustainable city, efforts are made to reduce carbon emissions, utilize renewable energy sources, promote green spaces, and ensure that public services are both accessible and effective.

Sustainable cities aim to create a balance between human activity and ecosystem preservation, fostering communities where people can live harmoniously with the environment. This involves integrating public transportation, walking and cycling infrastructure, and sustainable building practices to reduce reliance on automobiles and enhance residents' overall well-being.

In contrast, the other options do not align with the principles of sustainability. Prioritizing economic growth over environmental concerns neglects the long-term viability of resources and ecosystems. Encouraging suburban sprawl typically leads to increased resource use and inefficient land use, generating more environmental challenges. Lastly, eliminating all forms of transportation is impractical and counterproductive, as movement and accessibility are essential for urban life; instead, sustainable cities focus on improving transportation systems to be more efficient and environmentally friendly.
