Did you know that cities, although they only occupy 3% of the earth's surface, are responsible for approximately 75% of greenhouse gas emissions worldwide, according to the United Nations ? Likewise, according to a report from the Polytechnic University of Zurich , in 2070, 77% of cities will have the climate that a city located a thousand kilometers further south has today. Without a doubt, these data show the need to take measures to make cities sustainable. However, what exactly makes a city sustainable? Below, we explain what its characteristics are and give you examples of some of the most sustainable cities in the world. CTA Post The basic pillars of a sustainable city According to the Sustainable Cities Index , an annual report prepared by Arcadis in collaboration with the United Nations Human Settlements Program (UN-HABITAT), to define a sustainable city, the following three pillars of sustainability must be taken into account: People, Planet and Profits . People: the quality of social infrastructure is measured, such as quality of life, and other aspects related to health, education, crime, transport infrastructure or broadband.
Planet: at this point the quality of the environmental factors of a city is taken into account to be more resilient to climate change, such as air pollution, green spaces, waste management, energy consumption, gas emissions greenhouse effect, renewable energy and sustainable transportation . Benefits: the quality of a city's economy , business environment and infrastructure, accessibility, economic development or employment is evaluated . The top 10 Europe Mobile Number List characteristics of a sustainable city According to these three pillars, it is possible to identify various characteristics that allow us to classify a city as sustainable . At the end of the day, it is about turning into a reality these aspects that represent an improvement in the quality of life of people, in the economy and, above all, in the fight against the climate crisis that we face in this time. moment. In this way, a sustainable city has the following characteristics: Lots of parks and gardens One of the characteristics that we can easily perceive in a sustainable city is its large number of green areas .
However, these are parks and gardens that go far beyond the aesthetic: they have become the main solution for the absorption of CO2 in cities, considerably improving air quality thanks to the increase in vegetation. Alternatives to reduce CO2 emissions Now, the most efficient formula to combat CO2 emissions into the atmosphere is to reduce them as much as possible. In this sense, every sustainable city is characterized by promoting travel by bicycle, on foot or by public transport ―through specific infrastructures that encourage it―, in addition to multiplying electric vehicle charging points. Construction of sustainable buildings Sustainable buildings collect on a small scale the vast majority of characteristics that a sustainable city presents, with the firm purpose of minimizing the environmental impact of construction . The implementation of green areas, the search for maximum energy efficiency or the comprehensive well-being of its inhabitants are some of the hallmarks of this type of housing. when depositing it, and in the subsequent treatment of it by institutions. public, separating and recycling everything possible.
