A fully sustainable city is the goal that society must set itself, both at an individual level and as a common goal that we must achieve 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 minimize its environmental impact, promote social and economic equity, and foster 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 bicycle-sharing systems. Priority would be given to pedestrians and non-motorised mobility options. In addition, the use of private cars would be drastically reduced, and these would preferably be electric or powered by clean energy.
Renewable energy is another very important factor, as well as green spaces and biodiversity. The city would be supplied primarily by renewable energy sources, such as solar, wind, hydroelectric 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 the inhabitants.
Promoting access to local and sustainable food cannot be forgotten. Urban agriculture and the production of local, organic and sustainable food would be encouraged. The reduction of food waste and the adoption of healthier and more sustainable diets would be promoted.
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. Citizen participation in decision-making would be promoted and inequalities would be addressed.
In the current situation, smart technology would need to be implemented to monitor and manage city resources efficiently, such as traffic management systems, lighting and energy management. 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 economic prosperity, social equity and environmental health in the long term.
