3d Model of a Sustainable City.

Welcome to the future of urban living – a world where green cities have transformed concrete jungles into eco-friendly and sustainable communities.

It's a world where technology and nature have found the perfect balance, and humans and the environment coexist in harmony.

But what exactly are green cities? How do they function? And what makes them so important? Let's explore this idea further!

What is a Green City?

Green cities are urban areas designed with sustainability and green technology in mind, with the goal of minimizing their environmental impact while maximizing benefits for their communities.

Green cities prioritize reducing pollution, promoting energy efficiency, and increasing the use of renewable resources to create a healthier and more livable environment for their residents. The goal is to create a greener world through urban transformations.

This is achieved by incorporating sustainable transportation systems, green spaces, green technology and clean energy sources, social equity and affordable housing, as well as public health considerations into their design.

The design of a green city considers various living means, ensuring that the community thrives in harmony with nature. This involves making lifestyle and policy changes to enhance environmental health and the quality of life for their residents.

Now that you have a general understanding of what a green city is, let's take a closer look at the specific concepts and strategies involved in building these sustainable urban areas.

Key Concepts and Strategies for Sustainable Urban Living

Green cities function by incorporating a range of sustainable urban design principles and green infrastructure projects. To build a green city, several strategies need to be implemented.

These strategies focus on ensuring that the city is environmentally friendly and sustainable. Below are some of the key concepts and strategies that are used as well as some of the barriers we still face today that keep these from being implemented in cities across the world:

Sustainable Transportation

One of the most critical components of a green city is the implementation of >sustainable transportation. According to the Environmental Protection Agency (EPA), in the United States, 28% of the total greenhouse gas emissions are generated by transportation, making it the largest contributor to emissions in the country.

Green cities work towards implementing green transportation options that are more efficient and sustainable, aiming to reduce reliance on fossil fuels. These systems can include:

  • Extensive public transportation networks such as buses, trains, light rails, and subways.
  • Cycling infrastructure, such as bike lanes, bike-sharing programs, and secure bike parking facilities.
  • Eco-friendly transportation options such as electric buses, solar-powered trains, or hydrogen-powered taxis.
  • Greenways and park networks, which provide pedestrian and bicycle paths that connect parks, natural areas, and neighborhoods encouraging exercise.
  • Pedestrian-friendly streets designed with features such as wider sidewalks, crosswalks, and pedestrian-only areas.

These systems help to reduce traffic congestion, air pollution, and greenhouse gas emissions, while also promoting physical activity and more affordable transportation options for individuals and low-income families. A study by the American Public Transportation Association (APTA) found that individuals who use public transportation instead of driving can save an average of $10,000 per year.

Despite the benefits of sustainable transportation, it also comes with its challenges. One major issue is the high cost of installing and maintaining sustainable transportation infrastructure, which can be a significant barrier for low-income communities and small cities with limited resources.

Another challenge is that sustainable transportation often requires significant behavior changes from individuals, like using public transit, walking, or biking instead of driving.

In cities where cars have been the main focus for a long time, it can be hard to get people to use more environmentally friendly ways of getting around. This is even tougher in the suburbs or countryside, where these green options might not be available. That's why it's so important to make sure that there are choices for everyone accross all city zones to travel in a way that's good for the planet.

Renewable Energy

In addition to sustainable transportation, another critical component of building green cities is implementing renewable energy sources. According to the International Energy Agency (IEA), 19% of global energy-related and process-related CO2 emissions in 2021 came from the generation of electricity and heat used in buildings. This stat underlines the importance of transitioning to clean and sustainable energy sources to reduce the environmental impact of cities, combat climate change, and promote a healthier living environment for everyone.

Renewable energy sources such as solar, wind, geothermal and biomass energy as well as hydroelectric power, have the potential to provide clean and sustainable energy for cities. For example, the National Renewable Energy Laboratory (NREL) reports that just one hour of sunlight can provide enough energy to power the world's electricity needs for an entire year.

Let’s take a look at how these renewable energy sources can be implemented into cities.

  • Solar Energy: Solar energy can be harnessed in cities through photovoltaic (PV) panels installed on rooftops or open spaces such as parking lots, parks, and unused land. The panels can convert sunlight into electricity, which can be used directly or stored in batteries. Concentrated Solar Power (CSP) systems, which use mirrors or lenses to concentrate sunlight onto a small area, can also be used in cities to generate electricity. These systems are often installed in large-scale power plants located outside of the city, but the energy generated can be transmitted to urban areas.
  • Wind Energy: Wind turbines can be installed in urban areas, such as on rooftops, in parks, or on the outskirts of cities, to generate electricity from the wind. These turbines are often small and designed to operate quietly to minimize any potential noise pollution. Cities can also utilize large-scale wind farms, located outside of the city, to generate energy for urban areas.
  • Geothermal Energy: Geothermal energy can be utilized in cities through the use of underground hot water reservoirs or hot rock formations. Geothermal heat pumps can extract heat from the ground or water and transfer it to buildings for heating or cooling. This system can be used in homes, commercial buildings, and even large-scale district heating and cooling systems in cities.
  • Biomass Energy: Biomass energy can be utilized in cities through the use of waste-to-energy facilities that convert organic waste, such as food waste, yard waste, and paper, into energy. Biomass energy can also be produced from crops such as corn and sugarcane or from forest residue, which can be used to generate electricity or produce biofuels.
  • Hydroelectric Power: Hydroelectric power can be generated in cities through the use of small-scale hydroelectric power plants located in rivers, streams, or even in municipal water supply networks. In addition, tidal barrages and ocean energy converters can be installed in coastal cities to generate electricity from the motion of tides or waves.

Nature and renewable technology coexist in harmony with a hydroelectric power plant nestled in the heart of a lush forest, demonstrating the potential to accommodate sustainable infrastructure.

It's true that using renewable energy sources in cities isn't always easy. It can be expensive to build and keep up the infrastructure needed for renewable energy. Plus, renewable sources like wind and solar power can be less dependable than traditional sources like fossil fuels. But, even with these challenges, prioritizing renewable energy can help cities reduce the effects of climate change and move towards a more sustainable future.

Green Spaces

Green spaces like parks and gardens are crucial in creating livable and sustainable cities. They not only add beauty to the concrete jungle but also benefit the people and the environment.

According to the World Health Organization, access to green spaces can improve mental health and reduce stress, leading to better overall well-being.

In addition to these health benefits, green spaces also help to reduce the urban heat island effect, improve air quality, and provide habitat for wildlife.

Reducing the Urban Heat Island Effect

The urban heat island effect is when cities are hotter than nearby countryside because of things people do in cities, like building roads and using energy. The surfaces of buildings and roads absorb and release heat, which makes the air around them warmer. This makes cities hotter than the countryside.

Green areas such as vertical gardens, tree-filled parks, and rooftop gardens have the ability to absorb and reflect less heat compared to hard and reflective surfaces. Incorporating these spaces within urban areas can help lower temperatures, making the cities more comfortable for people and reducing the need for air conditioning.

For example, Central Park in New York City, home to over 18,000 trees helps to reduce the temperature in the city by providing shade and absorbing water that evaporates in the heat which cools air temperatures around them.

Improving Air Quality

Green spaces are not just great at absorbing heat. They can also absorb pollutants such as carbon dioxide, nitrogen dioxide, and particulate matter from the air, helping to improve air quality. On top of that, since most green spaces are covered with trees and plants, they release oxygen which is crucial for the health of humans and animals.

For example, in the United States, a study from Nowak, D.J. and Greenfield, E.J., US Urban Forest Statistics, Values and Projections. (2018), found that urban trees remove an estimated 822,000 tons of pollution each year, which is estimated at a value of $4.7 billion in savings from typical emission removal processes.

Providing Habitat for Wildlife

Green spaces can provide vital habitats for a variety of wildlife species, including birds, insects, and mammals. They can also act as stepping stones between larger natural areas, helping to support biodiversity.

Stanley Park in Vancouver, Canada is a 1,000-acre park that is a haven for wildlife. The park has a large lagoon that is home to many species of reptiles and fish, and the forested areas provide habitats for birds, mammals, and insects.

The Challenges of Creating Green Spaces

  • Urbanization and Development: One of the most significant challenges is urbanization and development, which can lead to the loss of natural spaces and green areas. As cities continue to expand and develop, there is often pressure to use available land for building structures, which can result in the reduction or elimination of green spaces. This problem is expected to worsen in the future, as the United Nations predicts that urban areas will grow by 2.5 billion people by 2050. This growth will put further strain on green spaces and make it even more challenging to create and maintain them.
  • Maintenance: Green spaces require regular maintenance, including watering, mowing, and pruning, to ensure that they remain healthy and attractive. These maintenance activities can require significant resources, including labor, equipment, and water. As a result, cities must balance the benefits of green spaces with the costs of maintaining them.
  • Public Resistance: There can also be public resistance to changes in land use, particularly if it involves the removal of existing structures or the use of public funds. This resistance can be challenging for city planners and policymakers who are trying to create new green spaces or expand existing ones. It may require engaging with the public to build support and address concerns, which can be time-consuming and costly.

Despite the challenges, prioritizing green spaces in urban planning and development can improve the quality of life for residents and promote sustainability. They can also add economic value to cities according to a study by the Trust for Public Land. The study finds that for every $1 invested in urban parks, there is a $10 return in economic benefits, including increased property values and reduced healthcare costs. Moreover, these green spaces contribute to economic growth by attracting investments and enhancing the city's appeal.

Greer City Park - A Shining Example of a Green Town with Urban Green Spaces

Greer City Park, a 12-acre park located in Historic Downtown Greer, South Carolina, is a prime example of a green space contributing to the sustainability and livability of a city. Built in 2008, the park has since become a beloved destination for both residents and visitors, open year-round and offering a variety of features and amenities for people of all ages to enjoy.

One of the park's notable features is a large meadow, providing a spacious and scenic area for recreational activities. This green space not only adds beauty to the city but also serves as a place for community engagement and physical activity. The park also includes a playground where children can engage in outdoor play, promoting their physical health and well-being.

Greer City Park also serves as a habitat for various wildlife species, supporting local biodiversity. It acts as a green oasis in the urban environment, providing a refuge for birds, insects, and other small animals.

Greer City Park shows how green spaces can be part of urban planning. Even with the challenges of development and maintenance, they are helping to create more green job opportunities for individuals. These spaces are key to promoting environmental sustainability, improving residents' quality of life, and adding economic value to the city.

Social Equity and Affordable Housing

Social equity and affordable housing are essential components in the development of sustainable and inclusive cities that prioritize green initiatives. According to the United Nations (UN) over a billion people worldwide live in slums or informal settlements without basic amenities such as clean water and sanitation.

Social equity means that everyone, regardless of their income or background, should have access to the same opportunities and resources. In a green city, this translates to providing affordable housing options in neighborhoods that have access to public transportation and other amenities.

One great example of a successful affordable housing program comes from Portland, Oregon. In 2016, city officials introduced an affordable housing program that obligated developers to allocate a portion of new units for low-income residents. As of 2022, the city's Housing Bureau confirmed that they have fully expended the funds allocated to the program and at its conclusion, the program will have created over 1,800 affordable housing units, which will benefit more than 4,000 city residents.

Programs like these help to ensure that everyone has a place to call home and can live in a neighborhood that meets their needs.

This also leads to healthier and more diverse communities. When people from different backgrounds and income levels live in the same neighborhood, they are more likely to interact with each other, share resources, and form connections. This can create a sense of community and help to reduce social isolation and loneliness.

Nevertheless, incorporating social equity and affordable housing into green cities presents various challenges. One of the biggest obstacles is the cost. Developing affordable housing in desirable areas can be expensive, and developers may be hesitant to invest in projects that may not be profitable. Another challenge is resistance from existing residents who may not want low-income housing in their neighborhood.

Despite these challenges, many cities are finding ways to implement social equity and affordable housing in green cities. By prioritizing these initiatives in urban planning and development, cities can ensure that all residents have access to the benefits of green cities. This not only promotes a more equitable and just society but it also creates diversified cities where various social and economic groups coexist and thrive.

Green Infrastructure

As our cities continue to expand, it is crucial to find ways to make them sustainable and eco-friendly. A promising solution is to integrate green infrastructure into urban design.

This refers to a range of natural or engineered features that can help manage stormwater, enhance air quality, and provide habitats for wildlife, among other advantages.

Let's take a closer look at some of the most effective ways to bring green infrastructure to our urban areas.

Green Roofs

These are roofs that are covered in vegetation and can absorb rainwater, help regulate building temperatures, and provide habitat for wildlife. Green roofs also reduce the urban heat island effect, which is when cities are significantly warmer than their surrounding rural areas due to human activities.

Green Roof System

An example of this would be the Chicago City Hall Green Roof. It is an award-winning example of green infrastructure. It covers over 20,000 square feet and includes more than 150 plant species. The green roof has reduced the building's energy consumption by 10-15%, improved air quality, and it can retain 75% of a 1 inch rainfall which helps to reduce stormwater runoff.

Rain Gardens

These are shallow depressions filled with plants that can absorb rainwater and filter out pollutants. Rain gardens provide many benefits. They help to reduce stormwater runoff from impervious surfaces like sidewalks, roads, driveways and roofs which can cause flooding and erosion.

They also improve the quality of water that enters the groundwater system through natural filtration. These can be created in anyone’s yard but you will also see these types of systems in cities and surrounding urban areas.

The RainWise program in Seattle incentivizes homeowners to install rain gardens and other green infrastructure to reduce stormwater runoff. One homeowner in the program transformed their front yard into a rain garden that can capture up to 1,700 gallons of rainwater per year, reducing their runoff by 95%.

Permeable Surfaces

Permeable surfaces, including pervious concrete, porous asphalt, and pavers, are designed to allow rainwater to infiltrate into the ground below. These materials create gaps or pores between them, enabling rainwater to seep through and be absorbed by the underlying soil.

Unlike traditional impervious surfaces like standard concrete and asphalt, which prevent water from infiltrating the ground, permeable surfaces play a vital role in protecting the environment.

They provide many benefits for managing stormwater runoff, such as recharging groundwater aquifers and reducing the amount of runoff that enters nearby waterways. This helps in maintaining the natural water balance and contributes to a cleaner and more sustainable urban environment.

Permeable Pavement Design Diagram

Stormwater runoff can carry pollutants like oil, fertilizer, and other chemicals into rivers and streams, harming wildlife and compromising drinking water supplies. By allowing rainwater to infiltrate the ground, permeable surfaces help prevent this, improving the quality of groundwater and reducing the need for costly water treatment processes.

Additionally, permeable materials trap pollutants and allow them to be broken down by natural processes, such as bacterial digestion and adsorption. This further contributes to protecting the environment by filtering pollutants from the water before it enters the groundwater system.

In Minneapolis, Minnesota, the city has installed permeable surfaces in several locations, including permeable pavers in parking lots at the University of Minnesota. The project reduced runoff by 86% and helped to improve water quality in nearby wetlands, showcasing a practical application of this environmentally friendly technology.

Living Walls or Vertical Gardens

Living Walls, also called vertical gardens, are walls covered in plants that grow vertically. They are very popular in cities because they add greenery to buildings and public spaces and have many benefits.

A significant benefit of living walls is their ability to purify the air by capturing and removing harmful pollutants. This is particularly crucial in urban areas where the air quality can be poor.

Living walls can also help buildings save energy by providing insulation. The plants act like a natural shield, keeping the building cool in the summer and warm in the winter.

Not only are they good for the environment, they also create homes for animals like birds and insects. Plus, being around plants and nature can make people feel happy and calm.

Living walls or vertical gardens come in all shapes and sizes and can be placed indoors or outdoors. You can find them in parks, plazas, and buildings like stores and homes.

The Living Wall at the Athenaeum Hotel in London is a stunning example of green infrastructure. The wall is made up of over 9,000 plants and provides insulation for the building. The living wall has helped to improve the air quality around the hotel and provides habitat for birds and insects.

Community Gardens

Community gardens are patches of land in cities where people can grow fresh fruits, vegetables, and herbs. These gardens represent a form of urban agriculture and help people in areas where healthy food is hard to find.

Besides providing fresh produce, community gardens also offer other benefits to cities. They can make the air cleaner by adding more green space and lowering the temperature. Additionally, community gardens can make people feel like they belong and help them make new friends, especially those who might feel left out.

Community gardens can also help cities be more eco-friendly by showing people how to compost and reduce their carbon footprint. Plus, they can be places where people learn about how to grow food in ways that are good for the environment and healthy for people.

All in all, community gardens are an essential aspect of urban agriculture and are important for cities because they help people get fresh food, make the air cleaner, bring people together, and teach about eco-friendly practices.

The GreenThumb Community Gardens in New York City is the largest community gardening program in the country. The program manages over 500 community gardens throughout the city, providing fresh produce for local residents and bringing together diverse communities. It also provides support, resources, and training to community members who want to start and maintain gardens in their neighborhoods.

This program helps people in New York City transform empty lots or abandoned spaces into vibrant, productive gardens where people can grow fruits, vegetables, and flowers. The program offers free gardening workshops, provides materials like seeds, tools, and soil, and connects gardeners with community resources and volunteers to help them maintain their gardens.

The program also hosts events like plant swaps and harvest festivals, where gardeners can share their produce and learn from each other. GreenThumb encourages people of all ages and backgrounds to get involved in community gardening, to promote healthy eating, environmental sustainability, and social connections within their neighborhoods.

Incorporating green infrastructure into urban design is a smart and sustainable way to create even more green cities in the future. By implementing features such as green roofs, rain gardens, permeable surfaces, living walls or vertical gardens and community gardens, cities can become more environmentally friendly, socially vibrant, and sustainable places to live.
