Sustainable Cities: Creating livable and sustainable communities


A sustainable city meets the needs of the present while ensuring that future generations can meet their own needs. To remain sustainable, a city must have robust social, economic and environmental systems.

A livable city is safe and clean, and provides its residents with access to quality education, healthcare and other essential services. A sustainable city builds on these livable factors to create an overall more resilient community.

There are many ways to create more livable and sustainable communities. Some key strategies are:

  • Investments in green infrastructure
  • Promotion of sustainable mobility
  • Promotion of energy efficiency and use of renewable energies
  • Supporting local food production
  • Prevent urban sprawl and encourage densification
  • Investing in social cohesion and community engagement.

Each city is different in creating livable and sustainable communities and will have its unique challenges and opportunities.

Today we look at what makes a city sustainable, some of the most sustainable cities in the world right now and what we can learn from them. We will also look at how existing cities can create more resilience to mitigate the effects of climate change.

Characteristics of a sustainable city

Characteristics of sustainable cities

Although every city is different, sustainable cities share certain characteristics. One of the most important aspects of a sustainable city is its infrastructure.

Sustainable cities are designed for efficient transport, with a focus on public transport, walking and cycling. They also have systems for recycling and waste management.

In addition, sustainable cities typically have green spaces that provide residents with a place to relax and enjoy nature.

Finally, sustainable cities are often designed to be more energy efficient and use renewable resources to power homes and businesses. By implementing these practices, cities can become more sustainable and better equipped to meet the needs of their residents.

Notable Sustainable Cities

Certain sustainable cities stand out from the rest.

Curitiba, Brazil is often cited as a model for sustainable urban planning. The city has an extensive public transport network, including buses and trains, which has helped reduce traffic and air pollution.

Additionally, Curitiba has invested heavily in green space, with over 80% of the city covered in parks and forests. This has not only made the city more livable, but also helped to offset the CO2 emissions.

Another sustainable city is Freiburg, Germany, known for its commitment to renewable energy. The city gets over 70% of its electricity from renewable sources, including solar and wind. In addition, Freiburg has placed great value on energy efficiency, all new buildings must meet strict energy standards.

As a result of these efforts, Freiburg has become one of the most sustainable cities in the world.

Tokyo is another sustainable living model. Despite being one of the most densely populated cities in the world, it has an incredibly efficient public transport system that reduces traffic congestion and air pollution.

Another green city, Copenhagen is known for its commitment to renewable energy, with over 60% of the city’s electricity coming from wind turbines. These examples show many different ways to create a sustainable city, and each city is unique in its approach.

There are several reasons why sustainability is critical in urban planning and in creating livable urban communities.

First, cities are responsible for a large percentage of greenhouse gas emissions, so finding ways to reduce these emissions is important to slow climate change.

Urban areas are also home to many people, so finding ways to make them more efficient and livable is crucial. These include reducing traffic congestion, improving public transport and creating green spaces.

Finally, sustainable practices can help improve the health of residents by reducing air pollution and providing access to fresh food and clean water.

Creating healthy, sustainable and cohesive urban communities

Creating healthy, sustainable and cohesive urban communities requires a multi-faceted approach. First, it is important to create accessible green spaces in cities. This can be done by converting vacant lots, creating community gardens, and creating parks and cycle/hiking trails.

Additionally, promoting healthy eating and active lifestyles is key to creating sustainable communities. Cities can do this through education and awareness programs that focus on nutrition and physical activity.

In addition, it is important to create a sense of cohesion in cities by promoting social inclusion and community engagement. This can be done through events and programs that bring people together and foster a sense of belonging. By taking these steps, cities can become places that are not only healthy and sustainable, but also cohesive and supportive.


Sustainable cities are resilient, which means they can adapt to changing conditions such as population growth or climate change. As both situations become reality and more and more people are moving to urban areas, we need to rethink our urban planning to create sustainable and livable communities that promote healthy living and a sense of community.
