A fully sustainable city is the goal that society must set for itself as an individual as well as a common goal that we must reach if we want to preserve our planet.
A fully sustainable city would be a place where a series of practices and systems have been implemented that minimise its environmental impact, promote social and economic equity, and enhance the quality of life of its inhabitants.
Some of the key features of a fully sustainable city are, for example, sustainable transport. Urban mobility would be based on efficient forms of public transport, such as trains, trams, electric buses and bike-sharing systems. Priority would be given to pedestrian and non-motorised mobility options. In addition, the use of private cars would be drastically reduced, and they would preferably be electric or powered by clean energy.
Renewable energy is another very important factor, as well as green spaces and bio-diversity. The city would be powered primarily by renewable energy sources, such as solar, wind, hydro and geothermal. Buildings would be designed to be energy efficient and self-sufficient, with solar panels, energy storage systems and conservation practices. The city would have a wide coverage of green areas, parks and natural spaces, promoting biodiversity and improving air quality and the health of residents.
Promoting access to local and sustainable food cannot be forgotten. Urban agriculture and the production of local, organic and sustainable food would be encouraged. It would promote the reduction of food waste and the adoption of healthier and more sustainable diets.
Of course, it would have to be a city that seeks social and economic equity, ensuring that all communities have access to affordable housing, quality employment and basic services. It would promote citizen participation in decision-making and address inequalities.
At this point in time, smart technology should be implemented to monitor and manage the city’s resources efficiently, such as traffic management, lighting and energy management systems. In addition, environmental education would be a fundamental part of the education system, and awareness of the importance of sustainability in society would be promoted.
The city would be prepared to meet the challenges of climate change, with resilience measures such as flood management, storm protection and long-term infrastructure planning.
Achieving a fully sustainable city is an ambitious goal that requires a joint effort by governments, communities, businesses and citizens. It is about creating an urban environment that promotes long-term economic prosperity, social equity and environmental health.
